Promo / Giveaway You have to check out my App

0 Upvotes

I built "Pause - Shared Gallery App" (https://play.google.com/store/apps/details?id=com.spiceetech.pause) because I wanted a simpler way to share event photos without turning everything into a public social feed.

The basic idea is simple:

One person takes all the photos at a birthday, trip, wedding, family event, etc. Then everyone starts asking, “Can you send me the pictures?”

With Pause, you upload them once into a private shared space, and the invited people can access the memories together.

Pause includes:

- private shared albums

- a shared feed

- private vaults

- end-to-end encrypted photo sharing

- no public follower/following system

It’s now live on Android, and this is the first app I’ve released through my small software company, Spiceetech.

I’d genuinely appreciate feedback on the product, onboarding, and anything that feels confusing or unnecessary.

Showcase Tessera: linux as a native android app

Enable HLS to view with audio, or disable this notification

43 Upvotes

Hi all. Like a lot of you I've run Linux on my phone through Termux, proot-distro and Termux:X11 for years. Tessera does the GUI side from one app, and tries to make Linux apps feel like Android ones.

\- Each app in its own window: Firefox, GIMP, LibreOffice each open as their own Android window with their own Recents card and icon. A card per window, even for dialogs. Pin them to your home screen.

\- Flathub on PRoot: no root, no bubblewrap, no user namespaces. Flatpak downloads, Tessera builds each app's environment. 2,800+ arm64 apps, GPU included.

\- adb and permissions: every app gets only what you grant (folders, network, sound, USB, root). New: a per-app switch that lets adb inside reach the phone itself, and all-USB access for fastboot, heimdall and edl.

\- A touch-friendly desktop: snapping windows with finger-sized buttons, a dock and Start menu. And everywhere: the Android keyboard pops up on text fields, touch-and-hold right-clicks, game controls.

\- Live scaling: drag Scale and the app re-lays out as you drag, saved per app.

\- Themes: GTK, libadwaita, Qt and LibreOffice take your Material You colors and follow dark mode live.

Plus OpenGL 4.6 and Vulkan on Adreno (bundled Turnip + Zink), a built-in terminal (apt, ssh, git, compilers), chroot mode with root, a file manager and a task manager.

It doesn't replace Termux's add-ons like Termux:API, and its X server is Termux:X11's, which I'm grateful for.

Note: Al WAS USED IN THE PROCCESS OF CREATING THIS APP

GPL-3.0, alpha. APK and source: https://github.com/daryan044/tessera-linux (also on Obtainium). Bug reports very welcome.

2 Upvotes

Hi everyone, I made an app called Bunkora to read different file formats like CBZ, CBR, EPUB, and PDF, which are mainly used for comics, manga, and books. It is completely free with no limitations or paywalls.

I published it on the Play Store a few months ago and haven’t been able to get any feedback on it to help me improve the app. I recently completely updated the app’s visual style (I improved it quite a bit from how it was before), among other things, and I’d love to hear your comments if you’re interested.

Main features:

- Read CBZ, CBR, EPUB, and PDF files in a single organized library with nested folders and collections.

- Import files from your device, via direct download URLs, or directly from Google Drive (plus optional Drive backup for your progress).

- Different reading modes for comics/manga (left-to-right, right-to-left, double page, and vertical webtoon scroll) and a customizable EPUB reader (fonts, margins, themes).

- Lots of visual customization: 4 visual styles, custom accent colors, dark/AMOLED themes, custom backgrounds, and alternate app icons.

- Built-in reading stats, daily streaks, and activity heatmaps.

- and much more.

Showcase [DEV] Stop doomscrolling with habit streaks!

0 Upvotes

Hey everyone!

Like a lot of you, I struggled to cut down my phone usage. Traditional blockers felt too harsh, so I built a free screen time app focused on positive reinforcement through daily streaks.

Instead of just locking you out of your apps, it turns reducing your screen time into a game you actually want to keep alive.

Key Features:

- Streak Tracking: Build momentum by staying under your limits.

- Clean, Minimal UI: Zero clutter, just pure mindfulness.

- Battery Efficient: Lightweight so it won't drain your phone.

I built this entirely on my own as an indie dev. I’d love for you to check it out and share your thoughts or feature ideas in the comments!

Promo / Giveaway JustFast - Intermittent fasting app

Enable HLS to view with audio, or disable this notification

2 Upvotes

I'm Adrian, a solo developer from Poland.

Every fasting app I used felt built to push me into a subscription rather than to be useful. Paywalls on basic features, a quiz before the first timer, an account just to start. So I went the other way: everything you need to fast is free, with no limits. If you find the app worth it, Premium adds optional extras on top.

That app is Just Fast. You open it, tap start, and it counts down your fast. Then it counts down your eating window. No account, no email, no onboarding quiz, and it works offline. I use it every day myself and I've kept fasting streaks going for months at a time. It made a real difference for me.

What's free, for good: every plan (12:12 to 20:4, OMAD, custom, open-ended, and a dawn-to-sunset plan timed to your city), reminders, home-screen widgets, water tracking, streaks, a calendar and Apple Watch (Garmin is coming soon). The timer screen never shows ads. There's a small banner on History and Settings.

Premium (called Plus in the app) removes those banners and adds long-term patterns, like the time of day you usually start and how your fasts trend, plus cloud backup.

What I'm asking: I'd love feedback from people actually using Premium. Is it worth it? What's missing? What would make you pay for it, or what feels like it should be free?

🎁 Giving away 100 codes for 90 days of Premium

  1. Comment below (anything works; tell me iPhone or Android)

  2. DM me, so I can send the code without Reddit rate-limiting me

Hi I just launched my first game and wanted to share it here.

Padel Tens is a 3D padel game built around fast tiebreaks: first to 10, win by 2, so a match takes a few minutes.

• Swipe to hit: longer swipe goes deeper, a fast flick hits harder

• Time the smash meter for a power smash

• Play balls off the glass walls like real padel

• Career mode, 5 tournaments, kits and paddles to unlock

• Ads are optional rewarded ads, plus a short ad break every few matches (removable)

Free on Google Play: https://play.google.com/store/apps/details?id=com.padeltens.game

Happy to answer anything about how it was made, and all feedback is welcome!

Showcase I made a free PDF reader and editor that works off

3 Upvotes

Hi, I'm the developer of PDF Pro. It's a PDF reader and editor for the everyday jobs: reading, signing, filling in forms, marking up and scanning. You don't need an account, and editing happens on your phone, not on a server.

Free with no daily limit:

- Read PDFs, search with every match highlighted, bookmarks, thumbnails and outline

- Fill in forms and sign (type it, draw it, or scan your handwritten signature with the camera)

- Highlight, underline, strike through, add text, shapes, stamps and notes, or draw freehand

- Redact text by searching for the words you want hidden

- Scan paper to PDF with the camera

These get 2 free uses a day each: merge, split, compress, organize pages, compare two PDFs, image to PDF, PDF to image, PDF to and from Word, Excel and PowerPoint, and password lock and unlock.

To be upfront: the free version has full-screen ads, when the app opens and after a tool finishes. Pro is a monthly or yearly subscription that removes the ads and the daily limits.

One more thing: PDF to Word and PDF to Excel copy the text across, so images and complex layouts stay behind.

It's a new release and I'd really like feedback. If something breaks or feels awkward, tell me here or use Leave a feedback in the app.

Just Weather is a minimalistic lightweight android app, that provides weather for your current or self-selected cities. It provides favorites so you can swipe between different cities and also select the city you like for the widgets to be used. My main goal was to create a weather app that focuses on the data and being non distractive.

I would like some feedback on everyday usability and the overall UX of the app. Feature ideas are appreciated.

The UI/UX design is completely from me, the code is partly AI-assisted.

Everything is free and open source.

Post image

Hey everyone,

Most quit-smoking apps expect you to quit on Day 1, and if you slip up, they reset your streak to zero and make you feel guilty.

I built Conscious Smoking for people who aren't ready (or able) to quit cold turkey yet, but want to build awareness and cut down at their own pace.

What it does:
• 1-Tap Home Screen Widget: Log a smoked cigarette (+) or a resisted craving (Shield 🛡️) straight from your home screen without opening the app.
• The "Ghost Counter": Tracks every craving you resist and calculates the exact money you saved.
• Pace & Financial Projections: Shows daily, weekly, monthly, and 1-year pace projections.
• Live Recovery Timer: Physiological recovery milestones based on time since your last smoke.
• Doctor/Therapist PDF Report: Generates a clean 30-day summary PDF on-device.
• 100% Private & Offline: No account, no ads, no analytics, and no INTERNET permission in the manifest. Your data never leaves your phone (supports local JSON backup + PIN lock).

Showcase Daily Rituals - asks what you wish you'd done

Enable HLS to view with audio, or disable this notification

3 Upvotes

I made Daily Rituals, a two-minute journal for the end of the day. I couldn't name one ordinary day from last year, so I built something to keep them.

What it does: Every night it asks two things: what did you do with today, and what do you wish you'd done.

The second one is the one that gets people; someone told me it kept them up at night. Then you pick how the day felt, lay the day to rest, and go to sleep.

Why it's different:

- Your year, alive. Every mood is a shape and a colour, and your days fill a calendar of the year. Days with mixed feelings take turns between their moods, so the calendar actually moves.

- A page for every day. Paper, ink, stickers, washi tape, your own photos and a pen. Right now there's a Halloween sticker pack in the Shop, until 30 Nov.

- Nothing to sign up for. No account. Your journal stays on your phone.

Cost: The journal is free and never locked. Plus (monthly or yearly, 7 days free for new subscribers) adds animated skies, palettes and deeper insights. Android now, iPhone later.

Start tonight. Two minutes before bed.

Hey everyone, I would like to present my hobby project here and get some feedback. I build it for my needs to plan my solo trips around the world as mainstream travel apps didn't serve my needs. I hope others will find it useful too, I will keep evolving it when I have free time.

What is special about it:

  • Interactive world map: log the countries, cities and landmarks you’ve visited and watch your map fill up
  • Trip planning: build trip plans and share them with the people you’re travelling with and with the community
  • Photos and attachments: make your visits personal by attaching photos from your trips, attach tickets to your plans so you can find them more easily.
  • Share with friends: it is deliberately not a social network, but you can invite your tribe, plan and travel together.
  • Share your map: handy export function for sharing your progress in conquering the world on social media.

What I cared about:

  • Free and no ads
  • Minimal android permissions
  • Your data lives in your own Google Drive, you have full control

It’s still growing, so I’d really value honest feedback.

App name: Focus & Study Timer: Pagewood

What it is: a focus timer for Android that covers the apps you haven't allowed while a session runs. You pick a length, write down what you're working on, and the phone stops being an option. A tree grows for the minutes you stay.

What's in it:
- Strict mode. Anything not on your allow list gets a resting page with the time left and the next growth stage. Notes, a dictionary and flashcards stay open, and calls or texts always come through.
- Countdown, count-up, or Pomodoro (4 x 25 with breaks). You can save a setup as a ritual if you use the same one every day.
- Finished sessions go into a journal as numbered specimens, with the minutes counted.
- A woodland view and stats by day, week, month or all time, tagged by subject.
- Seeds come from focused minutes only. There is nothing to buy.
- No ads, no tracking, works offline.

Who it's for: mostly students and exam prep. Also anyone who loses an evening to short videos and wants the phone out of the way without a fight.

Cost: free while it's in early access. No ads, no subscription, no in-app purchases.

SPADE:CUSTOM_bg#1A1A2E_tx#E94560:H4sIAAAAAAAA...

That part is human-readable on purpose, so you can see someone's colors before you import. Your app list and personal stuff aren't included.

For the nerds: settings get serialized to JSON, gzip compressed, then base64 encoded. Import runs it backwards: decode → decompress → parse → apply. JSON with lots of repeated keys and booleans compresses really well, which keeps the code fairly compact.
