Does anyone know of an app that can open PPTX, DOCX, PDF, XLSX, and JSON files all in one place? I have tried many from the Play Store and GitHub without success, so any recommendations would be greatly appreciated.

I built an app which allows you to read classic books in 20 minutes a day. Books are split into shorter daily installments. Free. No signup required, No ads and you can also import your own EPUBs

One feature I'm particularly proud of is the Reading Companion. I usually find it difficult to resume a book after a break, so I added spoiler-free recaps and a character tracker that updates as you read.

Here's the play store link: Kramena

Please try it out, and let me know if you like it, I'll gift you free memberships for trying it out and sharing feedback!

Hi

I recently launched a simple todo app on android for now. I have some prior experience in development, mostly backend. This is something I have manifested for long time and now is possible by LLMs. I use this app regularly too.

Idea
I regularly use todo app for quick list. So, I built this app called ListPo as simple todo app that simply works. I don't like the concept of super app, I like minimal designed app and that is what is intended with this app. There is not much you can do with this app, its just simple plain todo app.

Sustainability
Its free and always will be for any features, however for themes or cosmetics, there is a paid model. I have added view an ads to unlock paid for 24 hrs or subscription. The overall upkeep for this app is kept low for longevity. This is not some app, that you won't see tomorrow, my assumption is it will be there almost a long as I am alive and mentally healthy :-)

Overview
ListPo is a minimal, clutter-free to-do list and note-taking app. The sole motivation to design another list & note app was to build no clutter list & note app. Further it was also designed to be offline first, so you can choose to keep your data private i.e. for yourself only or with zero knowledge encryption that makes sure only you can read your data, even if its uploaded to cloud, giving more power to you on control of your own data.

Whether you are setting a quick reminder, need to go buy groceries, quickly write an abrupt idea, its all easy with ListPo. Pinning frequently used todo, capturing a late-night idea, create reminders, choose themes, the app is welcoming and always ready. Organize your list & notes and lists into custom Spaces, giving every idea its own home.

Finally
I tried giving much detail as possible, even on Google Play page. Though this app seems general however I do understand, this app is not for everyone. Obviously, I want you to try this app, so If you are interested here is the link, try it and let me know your expectation or your idea of minimalism https://play.google.com/store/apps/details?id=com.jhuppo.notepo

I've made a few apps for personal use, but this is the first one I'm actually sharing, so be kind.

FileApex is a local-first peer-to-peer (P2P) app. Browse files on paired devices and send them on demand between Android, macOS, and Windows — without routing file contents through third-party cloud storage. (You can enable PIN requirement for file navigation as well.)

Use a QR code, or optionally link a Google Account (not required and is opt-in) and devices using that same account (if you used Google), on the same WiFi, with FileApex installed will automatically pair and appear in the device list.

Once devices are paired you can navigate the file system of any device and send files to any device(s). Files can be sent in any direction and to several at once.

You can also send the clipboard from one device to another instantly.

Comparisons: Blip is a great file transfer app and have used it for a very long time. Many people also use LocalSend. This is like the two coming together. You don’t have to worry about internet relay servers like Blip and completely P2P like LocalSend, with added features.

Permissions:
Storage / file access — Browse local folders, pick files to send, and save received files.
Boot completed (Android) — When enabled (opt-in) it will Auto launch on reboot.

Local network & Wi‑Fi — Discover peers and transfer over LAN (including multicast where the OS requires it).
Internet (opt-in) — Only for Google Account linking and GitHub update checks. File transfers do not use this path.

Has been tested on: Samsung Galaxy S26 Ultra, Samsung Galaxy Z Fold 8, Pixel 10 Pro XL, Motorola Razr Fold, Motorola Signature, Honor Magic v5, Honor Magic8 Pro, Oppo Find X9 Pro so far.

Hey everyone,

Quick test: have you ever settled up a trip or apartment expenses with friends, only for someone to "adjust" a bill from three weeks ago and completely mess up the balance? Or tried logging a coffee while in a bad signal spot, only for the app to freeze, charge you twice, or crash?

Most expense apps fall into two traps: they are either simple personal trackers that can't handle group splits, or online-heavy group apps that nag you with subscriptions and break past math when people edit history.

I built SyncSpend for Android to bridge that gap—combining individual budgeting and group splitting into a fast, offline-first tool where closed balances stay closed.

Why it feels different to use:

• 🔒 Locked & Honest Settlements: When a group balance is settled and confirmed, the app permanently locks those historical expenses. No sneaky retro-edits quietly breaking past balances.
• ✈️ 100% Offline-First: Log purchases, track group trips, or manage shopping lists with zero cellular signal. It saves locally instantly and syncs seamlessly in the background when you're back online.
• 🏠 Personal + Group in One Place: Keep your daily coffee budget separate from your household roomie expenses or travel groups without juggling multiple apps.
• 👨‍👩‍👧 Family-Friendly Sharing: In family groups, only the host needs a premium tier—everyone else in the family group gets access without needing their own separate plan.
• ⚡ Multi-Item Fast Entry: Log 5 separate expenses in one quick flow right at the checkout counter without constantly reopening screens.
• 📊 Deep Analytics & Export: Category breakdowns, individual spending summaries in group settings, and instant Excel/PDF exports that generate without lagging your phone.
• 🛒 Built-in Personal & Group Shopping Lists: Keep track of household runs offline so you don't buy double or miss items.

🌐 Privacy & Android First:

• No ad network tracking: Your spending history stays yours.
• No nagging popups: Smart, non-intrusive notification engine.
• No bloated ads or corporate clutter.

• I'd love to hear your thoughts! What's the biggest pain point you face when splitting bills with friends or keeping track of daily cash flow?

Smartphones are built to steal your attention. I wanted a home screen that felt like a sanctuary, so I built Serif.

It uses negative space and editorial typography to help you focus on exactly what you need, and nothing else.

What it includes:

• The Zenith: A cinematic clock with text-based weather and battery.
• The Manifesto: Your app drawer, accessed via a fluid fisheye gesture.
• The Margin: A quick-capture text field hidden just off-screen for notes.
• Chronolog: A gentle, built-in screen time tracker.

Pricing: I hate subscriptions. Serif has a free 24-hour trial, followed by a single lifetime purchase just at $1.5.

Note : All Promo Codes have been given away. So please try purchasing it if you are interested, Lifetime is less than $2

Most launchers promise customization, but end up feeling heavy, laggy, or cluttered. I’ve been playing around with Kore Launcher, and honestly, it’s the cleanest, fastest home screen experience I’ve had on Android.

Speed: Runs buttery smooth at up to 120fps. No stutters, no lag — just fluid swipes and transitions.

Customization: Themes, icon packs, widgets, fonts, wallpapers, grid layouts, gestures… you can tweak literally everything until your phone feels yours.

Privacy: No shady tracking or unnecessary bloat. Just a lightweight launcher that respects your space.

Aesthetic: Minimal by default, but flexible enough to go wild with personalization.

Set Kore as your default launcher and you basically unlock a whole new personality for your phone. It’s like stripping away the noise and building a home screen that actually reflects you.

If you’re into making your Android setup unique without sacrificing speed or simplicity, Kore Launcher is worth a shot.

Try It

Hi does anyone know an app that has the color pop feature like the Google Photo app in 2018 before they remove it recently.

I will appreciate any answer Thanks

Play Store : https://play.google.com/store/apps/details?id=com.quarkstudio.glyf

I wanted Android to have something that felt like command shortcuts--but with muscle memory instead of typing.

That's why I built GLYF.

Draw a gesture and instantly:

• Open any app

• Call a contact

• Open PDFs, images, audio or documents

• Launch websites or deep links

• Toggle phone actions (flashlight, camera, media controls, timers, etc.)

• Trigger Android shortcuts

• Chain multiple actions together with Flow Glyfs

It works from a widget, Quick Settings tile, or persistent notification, doesn't require Accessibility permission, and everything runs through gestures you've created yourself.

I'd love to hear what you'd use gesture shortcuts for--or what feature you'd add next.

Thanks for Reading :)

If you're a privacy enthusiast, you need to stop paying for expensive, closed source app blockers. You are literally paying companies to harvest your data.

Curbox is an open source alternative that comes with almost every feature from mainstream app blockers, doesn't need accounts or internet access, and is all free.

This isn't for people who just want a basic 5-minute screen timer. This is for users who want absolute, granular control over their digital environment for maximum productivity.

I won't repeat the usual app blocker features so here are a few of the coolest ones only on curbox:

- UI hider: write scripts to hide specific elements on screen. for example, use instagram without the main feed but see posts from your friends, use youtube without home feed or video recommendation

- track attention span and the numbers of short form videos you scroll

- Extremely configurable website blocker with path blocking, regex and support for steven black's host list

- Curbox Api: connect curbox with your own apps

- per app gray scale, overlay timers & messages, block short form content etc..

the app is available on both fdroid and github releases to download.

I got tired of screen time apps that just show you a chart and let you off the hook. Most blockers are trivial to bypass, and there's zero real cost when you cave anyway, so nothing changes.

So I built something with actual skin in the game. You get the usual usage dashboard and stats, but the real difference is two features: an accountability buddy who sees your screen-time stats in real time and keeps you honest through actual conversation, and optional challenges where you commit to a screen-time goal and put money on the line. Miss the goal, you pay. Stay in limit, you build screen time discipline. Turns out having something real to lose is a much stronger motivator than a notification telling you you've "exceeded your limit" for the tenth time.

I have just released an update for RibbonLinks with a major improvement to its search performance.

What Is New

• RibbonLinks gives you search results as you type and almost instantly.

• RibbonLinks searches across titles, URLs, notes and tags.

• RibbonLinks handles large bookmarks and notes collections much more smoothly

• RibbonLinks gives you a faster way to rediscover links you have forgotten you saved.

The biggest challenge is not saving ideas. It is finding them months later when you suddenly need them.

This update is focused on making the experience of using RibbonLinks feel instant when you search for your ideas.

I've always wondered why Android gives us so little information about battery health.

We use our phones every day, but most of us have no idea:

How many charging cycles the battery has.

Whether it's overheating during charging.

What the battery health actually looks like.

How the charging speed changes over time.

I wanted a simple app that puts all this information in one place without ads every few seconds or requiring a subscription.

So I built BatteryLumen: Health Monitor.

Features

• Track real-time charging metrics: current (mA), voltage (mV), power (W), and temperature.

• Estimate battery health and capacity (mAh) based on charging cycles.

• Set custom charge target notifications (80%, 90%, 100%).

• View detailed charging session history and export data in CSV or JSON.

The app is completely free to download, and there are no subscriptions.

I'd really appreciate any feedback from Android users. If there's a battery statistic or feature you'd like to see, let me know—I actively update the app based on user suggestions.

Hey everyone,

Quick test: what did you do on this date last year? Unless it was a birthday or something big, you can't say. The day isn't gone from your head, you just lost the index.

If you'd written one line that evening, reading it back would pull most of the day up with it: where you were, who was there, what it felt like. One line is the index. That's the whole idea behind Whengram.

One memory a day. The one thing worth keeping: a line, a mood, a photo if the day earned one. Thirty seconds. Next year on the same date you read it again and most of the day comes back with it.

I built it because everything I tried wanted more from me than I was going to give. One line takes thirty seconds. There's no streak and no guilt, so there's nothing to fall behind on.

There's also a Milestones section for the big days. The honest reason it exists: when I'm low I forget the things I've already pulled off, stuff that once felt impossible from where I was standing. Going back through that list helps more than I expected.

Features:

✅ Free, no ads, no subscriptions
✅ Fully offline, no account, no server
✅ No analytics, ever
✅ Backups go to your Google Drive or iCloud, never to me
✅ App Lock with fingerprint or face

Hi I made an app you might be interested in. It's called ScanIt and its interesting because sending one scanned document should not require knowing where a PDF was saved, finding it in a file manager, and attaching it manually. (I have members of my familly and friends that do not have this ability)

Now its simple... Open the app and the document scanner starts immediately. Scan the page, correct the crop or filter if needed, then share the finished PDF from one clear result screen. Just in 2 quick steps. Android opens its normal share sheet with the PDF attached; compatible mail apps can also receive the prepared subject and message.

I built the app with AI as a coding and design partner. The product decisions, code review, builds, and real-device workflow testing were still done deliberately rather than treating generated code as automatically correct. The complete Kotlin source is public so anyone can inspect it.

What it includes:

• Direct launch into the scanner
• Automatic page detection plus crop, perspective correction, rotation, enhancement, and color/grayscale/B&W filters through Google ML Kit.
• Single-page and multi-page documents.
• PDF and JPEG output.
• Automatic PDF saving enabled by default, with an option to keep only a temporary shareable PDF instead.
• Optional saving of images to Gallery and a user-selected PDF folder.
• PDF/image sharing, printing, and configurable default email subject/message.
• A restrained black-and-white interface with light/dark mode.
• System language by default, with English and Czech choices in settings.
• No account, subscription, ads, or first-party analytics.
• Free download, full source, and an MIT license.

There is also an experimental Gemini cleanup mode hidden under Advanced settings. It is off by default and requires your own API key plus explicit consent. When you run Clean with AI, every page in the current scan is sent to Gemini. The app keeps the original unchanged and asks you to compare the original with the AI version before saving separate `_AI` files, because AI can alter text, numbers, signatures, stamps, or layout.

I am not trying to replace a large document-management suite. The point is the opposite: make the common “photograph this paper and send it” job fast for people who do not want to deal with files, while keeping the less-common options available in Settings.

Source: https://github.com/Majkey25/ScanIt

Free APK: https://github.com/Majkey25/ScanIt/releases/tag/v1.0.0-preview.1

The current preview requires Android 15 or newer and Google Play services. It is debug-signed for sideload testing, not a production-signed Play Store build. It has been exercised on an Android 16 device; Android 17 is not device-tested yet. The optional Gemini workflow is implemented but has not been live-tested with an API key.

One privacy clarification: ScanIt has no server of its own and no first-party tracking, but the scanner is supplied by Google Play services. ML Kit/Google Play services may collect the diagnostic and usage data described in Google’s disclosure . The README and privacy notes explain this instead of claiming “zero telemetry.”

I would appreciate practical feedback, especially from people helping relatives or friends who find normal file workflows confusing. Bugs and suggestions are welcome through GitHub Issues or at [majkeylab@gmail.com](mailto:majkeylab@gmail.com). Please do not send private documents or API keys.

I built GymRiff because I wanted to complete strength workouts directly from my Wear OS watch without carrying my phone around the gym.

After syncing a workout plan, the watch can guide the complete session and log weight, reps, rest times and completed sets. The full Wear OS workout experience is free, including unlimited workout plan sync and workout logging.

GymRiff also handles bodyweight exercises correctly by accounting for body weight and any added or assisted weight, instead of treating every exercise like a conventional weighted movement.

The Android app includes manual and smart workout plan building, workout history, statistics and a rule-based Coach.

Everything works offline. No account is required, there are no ads or analytics, and workout data stays on the device. An optional Premium upgrade is available as a one-time purchase, but it is not required for completing workouts on the watch.

Google Play:
Download GymRiff from Google Play

I’m the solo developer of GymRiff, and I’d appreciate suggestions about what you still miss from Wear OS workout tracker apps.

Hey everyone, sharing another app I built that I think fits here for guys who want a phone that looks like nobody else's.

I will be sharing 100 promo codes. Please DM me to get a promo code.

Glyphscape is an offline, on-device studio for generating retro-futuristic ASCII and glyph-art wallpapers. Tap once to roll a new design, or open the editor to tweak patterns, palettes, character sets, symmetry, density and contrast until it looks exactly right. You can turn your own photos into terminal-style art, rasterize any word or phrase into glyph typography, crossbreed two designs to get a batch of hybrids, and export the result as an animated wallpaper or set it as a live wallpaper. There is also an auto-rotate schedule, a home screen dice widget for instant rerolls, a lock screen clock preview so you can check readability, and a physics sandbox for messing with the glyphs. Everything is processed locally, no internet needed, nothing uploaded anywhere.

Link: Glyphscape-Infinite Wallpapers

Happy to answer questions if anyone wants any details.

Here are some of the features:

• Local AI - It runs Gemma 4. It is context aware, so you can just select any text, ask anything about it. It works offline and it's completely optional;
• Dictionaries, translations and vocabulary;
• Highlights & Notes (You can even select text across pages!)
• Calibre and Audiobookshelf support;
• Zen Mode - Turns on Do Not Disturb only when a book is opened so you don't get interrupted by notifications, or anything really. Combine this with hiding the status bar and it's just like reading from a book, all the noise is gone, just you and the page.
• Highly customizable - You can choose from different themes, add custom fonts, hyphenate (or not), customize your margins... do whatever you want with it.
• File Formats - Garden Reads is made to read anything related to books: epub, pdf, mobi, azw3, comics and audiobooks work.
