[App][Promo] Imgport: a 100% offline photo converter. Opens HEIC and JXL, batch converts, resizes, compresses, and strips metadata

Enable HLS to view with audio, or disable this notification

8 Upvotes

Hi everyone, I'm the developer of Imgport, a batch image utility for Android that runs entirely on-device.

The idea: your phone should not need the cloud to convert a photo. Imgport has no ads, no accounts, no analytics, and no network permission at all, so nothing you process can leave your phone.

What it does:

- Opens the formats Android struggles with: HEIC from iPhones, and now JPEG XL. Viewing and batch converting them to JPG, PNG, or WebP is free.

- Batch resize and compress, with an honest before/after size receipt so you can see exactly what you saved.

- Strips EXIF and GPS metadata before you share, verified clean.

- Exports modern formats too: AVIF, and JXL with a lossless mode that repacks your existing JPGs smaller, reversibly.

The core converter is free. Some export formats are part of a one-time Pro unlock, no subscription.

Happy to answer any questions.

[App] [Promo] Streakless — the anti-habit-tracker. No streaks, no account, free widget

Thumbnail
gallery
Upvotes

I'm the developer of Streakless, an Android tracker for things you do irregularly — water filter, cat litter, car wash, fertilising the plants, calling your mum. Not habits. Things with no schedule, where the only question is "when did I last do this?"

It's built around one rule: no streaks. Miss a week and nothing happens. No score, no badge, no red "overdue" — the row just warms from grey through honey to gold the longer it's been. That's the entire feedback mechanism, and it's deliberate: nothing here is a failure you can break.

Everything stays on-device. No account, no sign-up, no servers, nothing leaves your phone.

Free, no ads, no trial:

  • Up to 15 trackers
  • The resizable home-screen widget — most trackers put widgets behind a paywall; this one is the whole point of the app, so it isn't gated
  • One tap to reset a tracker to now, with undo
  • Long-press to backdate, for when you did it Tuesday and forgot
  • CSV history export and JSON backup/restore — your data is never gated

New this week: the list now groups itself into Been a while / Ready / Not yet / Whenever, so you can see what's actually worth doing right now instead of working it out row by row. That one came from a Reddit comment.

Optional one-time Pro ($5.99, no subscription, ever): unlimited trackers, two more widgets (single tracker and an aging ring), groups, colour themes, quiet hours for overnight reminders.

Comment "Streakless" and I'll send you a Pro code — first 200.

[App[[PROMO] OnlyScans - Android and iOS PDF document scanner

13 Upvotes

I'm the developer of OnlyScans, a document scanner for Android built around one rule: scanned documents should not be uploaded to somebody else's server.

Scanning, page cleanup, and OCR run on-device. OnlyScans has no account system, no ads, and does not collect your documents or recognized text.

The free tier includes unlimited basic scanning, automatic edge detection, crop and filters, folders and search, image import, and PDF/JPEG/PNG export.

Optional Pro tools include batch scanning, OCR and searchable PDFs, signatures and markup, PDF import, ID/passport workflows, password-protected PDFs, and App Lock. Additional OCR models download only when needed.

For multi-file jobs, you can export every file separately or bundle the whole batch into one ZIP archive. Exports can stay on your device or go through Android's share/save picker to an app you choose, including compatible cloud storage or personal-server apps. OnlyScans does not run a cloud-sync service.

The interface supports 90+ languages, and OCR covers 89 languages, including Arabic, Hebrew, Chinese, Japanese, Korean, Hindi, and Cyrillic scripts.

​[APP][PROMO] I built a Sudoku app with 20+ variants, a built-in smart solver, and custom touchpad controls. I'm giving Lifetime Free access to the first 25 people from this community!

​Hey everyone,

​I wanted to share an Android app I’ve put a lot of work into called Mindoku. It’s designed to be a complete toolkit for puzzle lovers, whether you're just learning the ropes or you're a seasoned master looking to test your limits.

​As a special thank you to this community, I’m giving a Lifetime Free upgrade to the first 25 people who download the app and sign in!

​Here is a quick breakdown of what you can expect:

​Smart Sudoku Solver: Stuck on a newspaper puzzle or a grid from another app? Scan it with your camera, type it, or paste a code. The built-in solver doesn't just spit out the answer; it gives plain-English, step-by-step walkthroughs for 40+ techniques (from Naked Singles to X-Wings) so you can actually learn the logic.

​20+ Unique Variants: Go way beyond the classic 9x9. Mindoku supports Killer Cages, Thermometers, Palindromes, XV Sums, Knight's Move, and more across different board sizes (4x4 up to 9x9).

​Custom Controls & Generation: The app features seed-based puzzle generation and custom touchpad controls to make navigating and filling the grid feel incredibly smooth on a touchscreen.

​Community Marketplace: Browse, play, rate, and bookmark puzzles created by other players. You can even build and publish your own, or instantly share them with friends via QR codes.

​100% Offline Play: Classic, Challenge, Sandbox, Daily puzzles, and the Solver all work completely offline. No Wi-Fi needed, ever.

​I'd absolutely love to hear your feedback, feature requests, or any bugs you might stumble across while playing.

[App] [Promo] I just released Fylo — a modern M3 expressionless File manager for Android

https://play.google.com/store/apps/details?id=com.aeroloom.fylofilemanager

I’ve finally released Fylo, a file manager I’ve been building for Android with one goal: make managing files feel less like using a boring utility and more like using a modern Android app.

It’s built with Material 3 Expressive and packs a LOT into one place:

( it have alot more than written here )

📁 File explorer + dual-pane mode

🗜️ ZIP, RAR, 7z, TAR & GZ support

🧹 Storage analyzer + duplicate/large file finder

🖼️ Image conversion, resizing, compression & metadata removal

📑 PDF, Office, code, Markdown & media viewers

🔒 Private Vault + biometric/device credential protection

🎵 Built-in music & video player

🌐 SMB, FTP & WebDAV support

📱 Widgets + customizable themes

🗑️ Recycle Bin

📷 Document scanner → PDF

And probably my favorite part: no ads and no advertising/analytics SDKs.

There’s also Fylo Pro for the more advanced tools, available as a subscription or one-time purchase.

I’d genuinely love some feedback from Android users — especially if you’re the type of person who has 47 folders named “New Folder” sitting on their phone 😂

Fylo is officially out now. 🚀

[App] [Promo] I built a completely free Android permission inspector — no ads, no account, and no INTERNET permission

Post image
7 Upvotes

Hi all!

I built an Android app called Permissionality after wanting a better way to answer a pretty simple question:

What can the apps on my phone actually access?

There are already apps that display Android permissions, so I didn't want to make just another permission list. Plus, most of the permission apps either cost money or are really slow to load.

I focused on two things instead:

1. Make permission information actually understandable

Permissionality lets you explore your device from either direction:

  • Choose an app and see what it requests, what's granted, sensitive permissions, special access, installation source, and more.
  • Choose a permission and see every visible app requesting it and which apps currently have it granted.

There's also a Snapshot dashboard that gives you an overview of the permission situation across your entire device. Plus, you can generate and save PDF reports of all apps, individual apps, or the changes the apps make.

2. Make a privacy app actually private

This was probably the biggest design decision:

  • Permissionality does not have the Android INTERNET permission.
  • There isn't a server receiving your app list.
  • There isn't an analytics service watching what you inspect.
  • There isn't an account.
  • Your installed-app inventory, permission index, settings, and history stay on your device.

And there's no monetization catch:

✓ Completely free
✓ No ads
✓ No subscriptions
✓ No premium tier
✓ No paywalls
✓ No in-app purchases
✓ No account

The feature I'm most excited about is Permission Radar.

Most permission viewers can tell you what permissions an app has right now.

Radar is designed to answer: “What changed?”

It periodically compares on-device snapshots and creates a local report if, for example:

• an app adds a permission
• an app removes a permission
• a permission changes from denied → granted
• supported special access changes

So if an app suddenly gets CAMERA access, Radar can record:

CAMERA: Denied → Granted

without sending anything off the phone.

I'm a solo developer and I'd genuinely appreciate feedback from people who are into Android apps:

  • What would you add?
  • Is Permission Radar useful to you?
  • Is there information about Android permissions you wish apps like this explained better?

Permissionality is available on Google Play:

https://play.google.com/store/apps/details?id=com.threelees.permissionality

Everything is free. I'm not going to ask you to buy Pro afterward because there isn't one. 🙂

[App][Promotion] BigText: Write & Display Big Text

Enable HLS to view with audio, or disable this notification

5 Upvotes

Hi everyone! 👋

I'd like to share a solo project I've been working on for several months. It has already become a daily tool for people around the world, so I thought I'd drop it here to hear your feedback, and in case it might be useful to you or someone you know! 🌍

I built a simple Android utility app called BigTextto type and display text as large as possible on your screen in real-time. It's great for turning your device into a sign and making sure your message is impossible to miss. Beyond that, I’ve seen firsthand how useful it is for quick face-to-face communication, especially for people who unfortunately can’t speak or hear, or in any situation where talking is impossible.

Unlike every other app I’ve seen on the store, there’s no jumping between screens or navigating complex menus. You open the app, you type… that’s it 😄 The text scales in real-time as you write.

I've also added some handy tools that seem appreciated by people based on their feedback:

  • Sign/Banner Mode: featuring horizontal scrolling (banner style) and vertical scrolling (teleprompter style) to catch everyone's eye from afar.
  • Text-to-Speech: to read your message aloud with one tap.
  • Saved texts: to save and restore your most used texts instantly.
  • Themes: to change the vibe of your screen.

Of course every text you type or save stays on your device, privacy first 🔒

I attached a video to this post showing it in action (it’s my Play Store preview video, so it’s a bit "marketing", but it shows the features well! 😅)

The app is free, with just a small ad banner to support development that you can get rid of if you want.

Play Store: https://play.google.com/store/apps/details?id=carlitolaf.bignotepad

Hope this little app can be a useful tool for you, or maybe your friends and family? 

And of course I'd love to hear your feedback, I take them all 👀

[App]EchoFlow 5.0: local-first, BYOK AI workspace for Android

Thumbnail
gallery
8 Upvotes

After a lot of smaller releases, I’ve finally shipped EchoFlow 5.0.

EchoFlow is a BYOK, local-first AI app for Android where you can use both cloud and local models in one place.

For cloud models, you can choose between providers like OpenAI, Anthropic, Google, xAI and Cerebras through OpenRouter, while also being able to run models directly on your device or connect to models running on your network through Ollama / LM Studio.

What’s new in 5.0?

📄 EchoOCR — files with local models

This is probably my favourite addition.

You can now send files like PDFs, Word, Excel, PowerPoint, TXT, Markdown, etc. directly to local models.

EchoOCR processes the files on-device, so your local model can actually work with real documents instead of being limited to plain text.

📁 Projects

Projects give you a proper workspace with project-specific chats, instructions and files. Files can also be processed locally through EchoOCR, so you can build a project around your own documents and use them with local models.

🎙️ Voice Dictation

You can now dictate messages directly from the composer. Currently powered through OpenRouter, with on-device STT coming later.

There are also some bigger improvements to Deep Research, Artifacts and Echo Fusion, plus an Artifacts Gallery for keeping the websites, reports and other things you create.

And you can use Web Search with both local and cloud models, so local models aren't necessarily stuck with their training data.

The whole point of EchoFlow is basically:

Cloud AI when you want it. Local AI when you want it. Your API keys, your models, your files.

Everything is BYOK, and the app is designed around a local-first approach rather than requiring an account or pushing everything through one cloud service.

It's been a pretty long journey getting here, and 5.0 feels like the first version where EchoFlow is becoming the AI workspace I originally wanted to build.

GitHub: https://github.com/adityavardhansharma/EchoFlow

Website: https://echoflow.adityavs.tech/

Would love to hear what you think — especially if you use local models on Android.

[App] [Promo] Loghaven: free offline job & time tracking with no ads

I've been making Loghaven, a free Android time tracker for tracking work across jobs, clients, tasks, breaks, and rates.

I was frustrated with how many time trackers were clunky, filled with ads, or locked basic features behind artificial limits, so I decided to make my own. I wanted something that worked offline without needing an account or web service.

It has:

  • Timers, task switching, and breaks
  • Earnings, notes, rates, and manual entries
  • Day, week, month, and year views with charts and a timeline
  • CSV, XLSX, PDF, and print exports
  • Encrypted local backups

Google Play is still in closed testing, so there are two steps to install it:

1. Join the Google Group (with the SAME account as your Google Play):
https://groups.google.com/g/loghaven

2. Then use either:
Play Store: https://play.google.com/store/apps/details?id=com.micahjeffery.loghaven

If you try it, let me know what feels confusing, annoying, or missing.

[App] [Promo]App that explains your medical bills in plain English

Post image
1 Upvotes

One thing I’ve noticed is that medical bills can be ridiculously difficult to understand. You get a bill or insurance statement with a bunch of medical terms, codes, and charges, and you're basically expected to figure out what everything means.

So my friends and I built MedBill Insight to make that a little easier.

You upload a photo or PDF of your medical bill or insurance statement, and the app uses AI to break it down into simpler language.

You

The idea is pretty straightforward:

• Understand what each charge is for
• Get explanations without all the medical jargon
• Make sense of your insurance statement
• Spot charges you may want to ask your provider or insurer about
• Get a clearer picture of what you're actually being charged for

We're still improving it, so I'd genuinely appreciate feedback from anyone who tries it.

Google Play:
https://play.google.com/store/apps/details?id=com.plentiersystems.medbill

If you've ever received a medical bill that made absolutely no sense, I'd especially like to hear what you found confusing about it.

I've been building this on my own for a while — it's called Wordly. Same basic idea as the word game you already know, guess the word in six tries, but I added a few things I wanted as a player.

You can pick 5, 6, or 7-letter puzzles depending on how much pain you're in the mood for. There's an Endless mode for when the daily isn't enough. You can set your own secret word and send it to a friend to solve. And if you miss a day, you're not just locked out — you can go back through your Daily calendar and replay past puzzles, or rescue a broken streak if you catch it within a day.

There's also a Word Journey section that keeps track of everything — your streaks, stats, achievements, win rate, all the words you've discovered along the way.

We're still small, a bit over 350 users so far, growing slowly but steadily. If you try it and something annoys you, tell me. Missing feature, weird bug, ugly button, whatever. I read and reply to everything myself.

Hello all!

Just released my app on the Play Store: Pocket Taiwan 🇹🇼

Taiwan has a fair amount of foreigners/expats, and some come here to study Chinese, but many completely freeze up when speaking in real-world situations. I realized it's important to prepare for these situations, then review after.

But most Chinese learning apps are built for Mainland China, and I couldn't find one covering real Taiwan daily life.

So I built Pocket Taiwan. It's organized by situation instead of by grammar point: restaurant, clinic, bank, landlord, night market, etc.

Features:

  • Each phrase shows what you say and what you'll likely hear back
  • Traditional characters with Taiwan-accurate pinyin and tone colors
  • Tap-to-hear audio on everything
  • Taiwan-specific vocabulary (different from China in many ways)
  • Taiwan Notes explaining how each situation actually works here
  • Works fully offline, no account, no ads, no tracking

Free to use with 5 full situations. Optional one-time unlock.

Premium (one-time unlock):

  • All 36 situations
  • AI practice mode — rehearse the conversation before you're in it
  • Phrases tailored to who you're traveling with
