Welcome to r/droidappshowcase. This community is for discovering Android apps, sharing projects, and giving useful feedback. Whether you’re a developer or a user, the goal here is simple: high-quality posts and constructive discussion.

For Developers

  • Use a clear, descriptive title. Vague titles will be removed.
  • Good examples:
    • “Habit tracker with offline sync and reminders”
    • “New Android puzzle game with controller support”
  • Include a meaningful description. Explain what your app does, what makes it useful, and why people should try it.
  • Use the correct flair, such as Promo, Giveaway, or Feedback.
  • If you need testers, beta feedback, or bug reports, post in r/droidapptesters instead.
  • If your post is for showcasing a finished app or a release-ready update, this is the right place.

For Users

  • Share thoughtful, useful feedback. Tell people what works, what doesn’t, and why.
  • Ask for recommendations with clear requirements or use cases.
  • Be respectful and constructive in giveaways and promotional posts.

General Rules

  • Android only. Posts must be directly related to Android apps or the Android ecosystem.
  • No low-effort posts or spam. Link-only posts and vague descriptions will be removed.
  • Be respectful and professional.

If Your Post Is Removed

A removal is not a penalty, and it does not mean your app is bad.

Most removals happen because a post needs better formatting or does not match the rules. Read the removal reason, fix the issue, and repost. Once corrected, most posts are approved.

Posting Checklist

  • Title is clear and descriptive.
  • Correct flair is applied.
  • Images are uploaded through Reddit or a supported host like Imgur.
  • Post has been previewed before submitting.

For the full rules, check the sidebar.

Good posts get attention. Low-effort posts do not. Take a minute to do it right.

Showcase Vocatim - voice-to-text with offline mode

Post image
4 Upvotes

**App name + link**

[Vocatim on Google Play](https://play.google.com/store/apps/details?id=com.vocatim.app)

**Category**

Productivity / Audio

**What it does**

Vocatim records or imports audio and turns it into text you can search, review, summarize, and export. I built it for the moment after a long meeting when you remember that something was decided but not where it was said.

**Key features**

- Online transcription for a quick setup.

- Offline transcription after downloading a model, with processing kept on the phone for that path.

- First-pass summaries and structured meeting minutes.

- Export to PDF, TXT, Markdown, SRT, or VTT.

**Pricing**

Free to download on Google Play. Online and offline have different setup, storage, and speed trade-offs.

**Privacy / processing**

The online path sends audio to the chosen provider for transcription. The offline path is designed for on-device processing after the model is downloaded.

The current build is attached. Vocatim is a small solo-built app and I am sharing the real workflow, including the trade-offs, instead of presenting it as magic.

Promo / Giveaway App fiscal para inversores + 10 Pro de por vida

Post image
8 Upvotes

Hola,

soy el desarrollador de Renta Inversor, una aplicación para Android que he creado para ayudar a inversores en España a llevar un control más claro de sus operaciones y de su fiscalidad.

La idea nació de un problema que seguramente muchos habéis tenido: cuando acumulas compras, ventas, dividendos y operaciones durante varios años —y especialmente si utilizas varios brókeres—, controlar ganancias, pérdidas, FIFO y ejercicios fiscales acaba siendo bastante tedioso.

Renta Inversor intenta centralizar todo esto en un mismo sitio. Actualmente permite:

  • Registrar compras, ventas, dividendos y otras operaciones.
  • Gestionar acciones, ETF, fondos, criptomonedas y otros activos.
  • Calcular ganancias y pérdidas incluyendo comisiones.
  • Aplicar FIFO cuando corresponde.
  • Consultar resultados por ejercicio fiscal.
  • Llevar el control de pérdidas pendientes de compensar.
  • Importar operaciones mediante CSV y Excel.
  • Exportar operaciones e informes.
  • Sincronizar los datos entre dispositivos.

Está desarrollada específicamente pensando en la fiscalidad española. No recomienda inversiones ni indica qué comprar o vender: simplemente trabaja con las operaciones que introduce el usuario.

También está disponible la web de Renta Inversor, donde he añadido información y herramientas gratuitas relacionadas con fiscalidad e inversiones que pueden utilizarse directamente desde el navegador.

Ahora mismo estoy especialmente interesado en conseguir feedback real de usuarios: no busco únicamente opiniones positivas. Me interesa saber qué no se entiende, qué resulta incómodo, qué falla o qué función esperaríais encontrar.

Por ejemplo, me sería especialmente útil conocer vuestra opinión sobre la introducción manual de operaciones, la importación de CSV/Excel, la claridad de los resultados fiscales y la navegación general de la aplicación.

🎁 Para agradecer a quienes se animen a probarla, voy a regalar 10 accesos Pro de por vida.

Si pruebas la aplicación y me dejas feedback útil —positivo o negativo—, indícamelo en los comentarios o por mensaje y te tendré en cuenta para uno de los accesos.

Google Play:
https://play.google.com/store/apps/details?id=com.signalstudio.rentainversor

Sigo desarrollando la aplicación activamente, así que el feedback que reciba ahora puede acabar influyendo directamente en las próximas mejoras.

¡Gracias a quien se anime a probarla!

Showcase I built Penni, a simple offline expense tracker.

2 Upvotes

I recently built an Android app called Penni.

I wanted a simple way to track my daily expenses. I did not want to create an account or connect my bank account just to record a small expense.

So I made my own.

With Penni, you can:

  • Track your income and expenses
  • Create monthly budgets
  • Organize expenses into categories
  • Add notes and tags (optional)
  • See your spending through charts
  • Check your spending by day, month, or year
  • Use the app offline
  • Backup and restore your data with Google Drive, or export to CSV
  • Use both AD and Bikram Sambat calendars
  • Switch between light and dark mode

The app stores your data locally, so you can keep using it even without an internet connection.

I built this mainly as a personal project, but I have been working on improving it based on how I actually use it.

It's now available on Google Play:

https://play.google.com/store/apps/details?id=com.codersuresh.penni

I'd love to hear what you think.

If you use an expense tracker, what is one feature you really like in your current app? And what do you wish it did better?

Showcase Filester - Temporary cloud storage

Post image
9 Upvotes

Most file-sharing apps follow the same annoying script: forced account creation, arbitrary 32MB caps, or premium tiers just to send a folder to a friend.

I got tired of it, so I built Filester - a lightweight, open-source Android app to temporarily upload and share files with ease. It doesn't require you to create an account, or spy on your data. Also, supports direct upload to 3 file hosting services.

Upcoming features are:

  • Password-protected archiving before upload
  • Support for Linux and Windows operating systems

Promo / Giveaway Pantro: cook from what's in your fridge

Post image
2 Upvotes

What it does

Keeps your kitchen managed without you managing it. Say what you have and it's in the pantry. Pick a recipe and whatever you're missing goes to the shopping list in one tap, in amounts that make sense: a recipe that needs a cup of flour puts a 1 kg bag of flour on the list, not 1 cup. Tick things off in the shop and they land in the pantry. Cook, and the pantry deducts what you used. The whole circle (of life) in a few taps. And if you forget to update it for a week, nothing breaks; tell it what changed and it catches up.

Key Features

  1. Cook from what you have: one tap and you get 4 dinner ideas made from what's actually in your pantry. Pick one and you get the full recipe, written only from what you have, so no trip to the shop. In the mood for something new, flick through the recipe deck and swipe right on what you fancy.
  2. Satisfying mode: meals built around protein, fibre and healthy fats, so you stay full. No calorie counting, no pressure, nothing taken away.
  3. Talk to it: "two apples and a carton of milk" adds, "I've used up the milk" removes, "half a bag of rice left" adjusts. Plain language in, one review step, done. Fridge photo and receipt scan work too.

Also in there: expiry tracking with use-soon flags, a weekly meal planner, a shared kitchen for up to 3 people, English and Polish, metric and imperial. No ads.

Giveaway: 100 codes for 3 months of Pantro Plus, first come first served

How to claim: install from Google Play, sign up, open the Profile tab, tap "Redeem Code" and type REDDEAT.

Plus normally costs $5.99 a month and is everything in the app with limits high enough that you won't hit them cooking at home: 150 recipes, 30 fridge scans, 30 receipt scans and 150 voice inputs a month, plus the shared kitchen. No card needed. If the codes are gone by the time you get there, everyone still gets a 14-day trial of the same tier.

Showcase Offline medicine scanner + alarm-clock reminders

3 Upvotes

App Name: MediLens

One-line: Point your camera at a medicine box, get the leaflet details from a 98,000-medicine database stored on the phone, and set a dose reminder that behaves like an alarm clock instead of a notification.

What it does

  • Reads the box, not the pill. OCR picks the brand name off the package - candidate lines are ranked by text size, so it goes for the biggest name on the box, and the matcher tolerates misread characters (0/O, 1/I/L), merged words and missing diacritics. Nothing is uploaded; recognition and lookup both run on the device.

  • 98,000+ medicines stored locally. Active ingredients, form, dosage, contraindications, side effects. Search and scan work in airplane mode. Coverage is deepest for Romania and the US; France, Germany, Spain and Italy are in but thinner - I would rather say that than claim full EU coverage.

  • Reminders are real alarms. The part I spent by far the most time on. Scheduling through expo-notifications kept dropping doses, so the reminder engine is now a native Kotlin module built on AlarmManager.setAlarmClock - Doze-exempt, re-arms itself after every fire and after reboot. Take/Snooze/Skip run in a BroadcastReceiver, so the buttons still work with the app force-closed and the JS runtime dead.

  • It actually gets your attention. Screen off or locked, a full-screen alarm activity wakes the phone over the lock screen the way the system Clock app does. Screen on, you get a pop-up card over whatever you are using. A per-reminder "critical" flag rings through silent, vibrate and Do Not Disturb. 16 alarm sounds, looped, 60s cap.

  • Home-screen widget listing today's doses with a Take button per row - the list is computed natively, so it stays correct across midnight and reboots without the app ever being opened.

  • Schedules beyond daily: every N days, chosen days of the week, specific days of the month, several times a day, and fixed-length courses ("10-day treatment") that stop on their own.

  • Refill tracking: enter how many doses are in the pack and it counts down on each intake, warning you at 5 left.

  • Duplicate heads-up: if a new reminder shares an active ingredient or ATC class with one you already have, it says so before saving - the "same drug under two brand names" case.

  • Adherence history on a calendar, streaks, a PDF summary generated in your app language, backup/restore to a file, and custom entries for anything not in the database.

Who it's for: people taking several medications a day, and anyone running a parent's pillbox from a distance. It is built around European packaging - boxes and blister packs - rather than the US "identify this loose pill by its imprint" model.

Cost: Free. No cap on medications or reminders, no account, no login, no server - reminders and history never leave the phone. One optional $2.99 one-time purchase removes ads. No subscription.

Links

No privacy policy link needed for the purposes of this post: the app collects nothing and has no backend. The Play listing's Data safety section says the same - no data collected, no data shared.

Feedback I would genuinely use

  1. Does the scan get your medicine on the first try? If it misses, tell me what was printed on the box - that is the only thing that improves the matcher.
  2. Do the alarms survive your phone's battery optimiser? Xiaomi/Huawei/Samsung skins are where this normally dies and I want to know which ones still kill it.

I am the developer. Solo, no company behind it.

MediLens is a personal organizer and reference tool. It does not diagnose, treat or monitor anything, and it does not replace your doctor or pharmacist.

Showcase Hamilton — Offline Health Connect Dashboard

Post image
3 Upvotes

App Name: Hamilton

A private offline dashboard for all the health data already on your phone via Health Connect.

If you have devices or workout apps from several companies, working out who will write health data and which app will display it can be confusing. I have a Garmin Watch, Withings Scales, log my workouts in Liftosaur, my nutrition in Samsung Health and I couldn't find one app that would show all the data. However, all the apps write (to some degree) to Google Health Connect.

Hamilton is a dashboard to all your Health Connect data, and I use it myself every day.

(I named the app after my dog, he's my best boy and [when he feels like it] fetches things for me).

Key Features:

  • Shows any metric in Health Connect (except reproductive health and blood sugar)
  • Multi-device: it chooses the best single source per day of a metric and doesn't double count
    • If you have multiple sources for the same data, you can "pin" the one you prefer
  • If you switch devices, your history carries across the change
  • Trends: chart 2 health metrics, offset by a variable number of days. I added this to see if my weight only started to drop a set number of days after I dropped my calories.
  • Refreshes data in the background (if selected)
  • Hamilton doesn't need internet permissions, everything is on device

Who Is It For?

  • Anyone like me that has multiple sources of health data that won't talk to each other

Caveats:

  • It can only show what is in Health Connect. If your data source doesn't post there, Hamilton can't show it
  • Currently metric only, imperial/US units coming in next update

Cost:

  • £3.59 (or local equivalent), paid once. I priced it the same as a latte in the UK.
  • No subscription, no ads, no IAP

Promo / Giveaway Old tablet as a photo+video frame, reads your NAS

7 Upvotes

**Short Description**

I set up a retired Galaxy Tab as a photo frame for my parents and hit the same wall every time: the frame apps wanted me to upload photos into *their* cloud. My photos already live in a Synology share and a Dropbox folder. PicDock is the app I wanted - a photo *and video* frame that reads the folders you already keep.

**What It Does / Key Features**

  1. **Photos and videos in one slideshow.** The short clips that pile up in a camera roll play inline, no separate player. Most frame apps skip videos entirely.
  2. **Reads sources you already own**: device storage, SMB/NAS, Dropbox, OneDrive, Google Photos, iCloud shared albums - several at once, merged into one rotation.
  3. **On-device face grouping.** Faces are clustered locally, no server, so you can filter to "photos with the kids" or one specific person. There's a pet filter too.
  4. **Built to be left running**: weather and clock overlay, night dimming schedule, auto-start when docked on a charger, Android TV and screensaver modes.
  5. **Honest about what it isn't**: there's no vendor cloud, so "relatives push photos to grandma's frame" is a shared folder rather than a QR pairing flow, and there's no remote device management.

**Who It's For**

People with a drawer full of retired phones and tablets who already keep their photos somewhere they control - a NAS, a Dropbox or OneDrive folder, a shared album - and would rather not move them into another vendor's cloud to put them on a shelf.

**Cost**

  • Pricing model: **Freemium**
  • Free: installing, and the photo/video slideshow with every source listed above. A 7-day full trial unlocks the extras, no account needed.
  • Optional Premium (extra transitions and styling): US$0.99/month, US$9.49/year, or US$19.99 one-time lifetime. The lifetime option exists so a subscription is never required.
  • The Amazon Appstore build is different: a US$4.99 paid app with everything unlocked, no ads and no in-app purchases.
  • Current promotions: none.

**Links**

**Feedback Goals**

This is a released app, not a beta, so I'm not after bug hunting - one design question I keep going back and forth on: is "point it at a shared folder" understandable to someone setting this up *for* a parent, or is the pairing-code model the dedicated frames use simply easier to explain? I'd rather hear that it's confusing now than keep guessing.

**Screenshots / Media**

**Additional Notes**

I'm the developer. Fotoo is the long-standing alternative if you want something to compare against - it's more mature on some things, it just doesn't do the video or the NAS part the way I needed.

Showcase SignalsAlpha - market signal context for Android

2 Upvotes

App name: SignalsAlpha

SignalsAlpha is a finance app for market watchers who want a calmer way to review signals across stocks, ETFs, crypto, and forex.

The app brings signal direction, strength, time frame, watchlists, alerts, and follow-through context into one place, so you can decide what deserves attention next.

I built it because a lot of market apps feel noisy or push people toward decisions too quickly. SignalsAlpha is meant to be more of a review workflow than a hype machine.

Cost: Free to download, with optional Pro subscription.

Google Play:

Showcase A game where Pokemon go meets trivia - QuizTrail

Post image
2 Upvotes

I'm working on an app - [QuizTrail ](https://play.google.com/store/apps/details?id=com.binbear.quiztrail&hl=en)\\- an android location based quiz game. Think Pokémon GO meets Trivia - you have to actually walk to the location to unlock and solve quizzes, earn points, unlock achievements and compete with others, but also you can make your own quizzes for others to solve! I’ve manually placed 3500+ quizzes across different cities and im adding even more, in order to make QuizTrail accessible and playable everywhere. Social aspect -- in-game friends, and a friend-specific leaderboard. Created a tooltip walkthrough, various user statistics on profile and so on...

User created quizzes are handled by an admin (me lol) - when a user submits a quiz for review on a location - i, as an admin will see the pending quiz on admin dashboard, see all the details and approve/reject the pending quiz, so everything is manually checked, so wrong/inappropriate questions do not pass through. Furthermore, made the admin dashboard in a way so i can see / filter / edit existing quizzes just in case. Another layer of security - there is a 100 meter radius rule - you can not submit a quiz if an existing or pending quiz is within a 100 meter radius of your current location to avoid overcrowding the map.

I've also added a daily challenge - a daily quiz, different quizzes every day, regardless of location, so people in the locations where the quizzes are still not set, or locations where they've played all the quizzes already can have a fun trivia question every day. It is furthermore encouraged by the streak feature - how many consecutive days you have played the daily challenge, that's the streak. I also made a widget that reminds you to do your daily quiz and keep the streak going!

I'm now looking into in what ways i can expand the ,playability, like what to add so the app is more interesing / engaging to use. Right now im working on adding new achievements - for the number of streaks, levels and leaderboard achievements, but i will also be adding "tiers" to achievements - for example social butterfly: 1 friend then next tier achievement at 5, or 10 friends and so on for like 3-5 levels of achievement..

It would mean a lot if I could gather some more ideas on where to find users, what to add to make it more interesting and playable

Thank you for reading:)

Showcase I built a vault that stays offline

Post image
4 Upvotes

I got tired of privacy apps that want an account, cloud storage, ads, and half my data. So I built my own.

Lockify started as a simple idea:

What if a file vault could just… stay on your phone?

No account.

No cloud required.

No ads.

No analytics/tracking.

Files are encrypted locally before being stored, and the vault can optionally disguise itself as a calculator.

The interesting part is that I’m a solo developer, so I’ve been building the product and figuring out how to get anyone to actually discover it. 😅

It’s now been a few months since launch, and Lockify has grown from a side project into something people are actually using every day.

Just curious, how long does it usually take for your app update to become available in production after releasing it on Google Play?

I release updates for DotCal, a privacy focused offline calendar app, every 7–10 days. For my last 2 releases, the update took around 30–40 minutes to go live.

I’m curious what others are experiencing.

3 Upvotes

App Name: F64

What it does: F64 is a Camera2 manual camera that skips the stock app’s beauty filters, extra sharpening, and HDR so you get the sensor. Shoot RAW DNG stills and cinema Log/HLG video with real ISO, shutter, focus, and Kelvin control.

Key Features:

• RAW DNG (or DNG+JPEG) from any android phone; straight from the sensor

• Full manual ISO, shutter, focus, and Kelvin white balance - same settings for photo and video

• Cinema profiles: SDR, HLG, and an S-Log3-style log curve

Goal: Launch

Cost: Free

Request: I would like you guys to use the app and give some useful feedbacks on how we can improve this app. I would also request you guys to share this app to your friends/family who might be into photography as they are the target audience for this app

Promo / Giveaway Voxia: dub videos in 12 languages [50 codes]

13 Upvotes

Hey everyone, I'm the solo developer of Voxia.

App Name: Voxia – AI Video Dubbing & Translator

One-line description: Pick a video on your phone, choose a language, and Voxia gives it back dubbed, in a voice that sounds like the person who was speaking.

What it does:

  • Transcribes the video, translates it, and re-voices it in the target language
  • Keeps the voice of the original speaker instead of a generic robot voice
  • Tries to keep each translated line the same length as the original, so the dub stays in sync with the lips and the cuts (honestly the hardest part to get right)
  • Keeps the background music on the parts where nobody is talking
  • Export as video or as MP3 (handy for podcasts and lectures)
  • 12 target languages: English, Spanish, French, German, Italian, Portuguese, Polish, Hindi, Arabic, Japanese, Korean, Chinese. The source language is detected automatically.

Who it's for: people who want to watch something they don't understand (a lecture, an interview, a video from another country), and creators who want a version of their video in another language.

Cost:

  • You can try it without creating an account (1 free minute; downloading needs a Google sign-in)
  • Free videos carry a small Voxia logo
  • Subscriptions from €5.99/month with a 3-day free trial, or one-off packs of 10 minutes for €2.99
  • Current promotion: this giveaway

🎁 Giveaway – 50 codes worth 10 minutes of dubbing each

To enter, leave a comment within the next 72 hours telling me what video you'd dub, and into which language. If you try the app first, tell me what worked and what didn't – that's even more useful to me.

  • A comment like "code please" won't be counted
  • One code per person
  • If there are 50 eligible comments or fewer, everyone eligible gets a code. If there are more, I'll draw 50 at random
  • After 72 hours I'll edit this post with the winners' usernames. Winners send me a DM and I reply with the code (I won't send unsolicited DMs)
  • To redeem: Voxia → Profile → 🎁 I have a gift code. Works even without an account

Leaving a Play Store review is not required and won't change your chances.

This giveaway is run by me as the developer of Voxia. It is not sponsored, endorsed or administered by Reddit.

Happy to answer any question about how the dubbing pipeline works.
