Hello everyone,

I've built Bindery, an Android PDF utility app focused entirely on privacy and offline usage. By design, the app has absolutely no internet permission in its manifest, meaning your documents never leave your device.

What the app does:

* Create PDF booklets (signature/saddle-stitch layouts - quite rare to find offline on Android)

* Merge, rotate, and number pages

* Built-in PDF reader with landscape mode & night theme

* Image-to-PDF conversion with automatic perspective warping correction

* Custom watermarking

What I'm looking for:

Google Play Console requires me to have at least 12 testers opt-in for 14 continuous days before going public. I am looking for testers who actually use PDF tools on a regular basis, are willing to keep the app installed for the test duration, and can share some honest feedback.

What you get:

* Ad-free, tracking-free, and fully offline early access to the app.

* Fully verifiable privacy claims via the public GitHub repo linked above.

* Access to a self-hosted community hub (uses Google OAuth for convenience, no separate account creation needed, and features full delete-on-demand) where you can report bugs privately or chat about the project.

How to join the closed test:

I set up a self-hosted signup hub to automate the Google Group onboarding process:

Thank you for your time, and I look forward to your honest feedback!

Hey everyone.

Wanted to put together a solid overview of the app in one place since a lot of people ask about specific features and it is not always obvious where to find them. I also want to make sure people know this app runs properly on Android TV, Amazon FireOS, and Fire Stick devices, because that tends to get overlooked. More on that below.

Android TV, Amazon FireOS and Fire Stick
This is worth calling out properly because it is something UFM Pro does that most file managers simply do not. The TV version is not a phone app stretched to fit a big screen. It has been built specifically for TV environments with full D-pad navigation throughout. Every screen, every menu, every interaction is designed to be used with a remote control. No touch required, no awkward zoomed in phone UI, no broken focus states.

Install via the Downloader app using code: 1581139 for Amazon Devices, I am in the process to have it on the official Amazon Store.

If you have ever installed a file manager on your Fire Stick or Android TV box and ended up with a cramped phone layout that barely works with a remote, UFM Pro is a completely different experience.

Menus are laid out for 10 foot viewing distances, navigation flows naturally with the D-pad, and nothing requires you to dig through a UI that was never meant for a remote control.

TV specific features include dedicated pairing screens for device to device connections, separate auth flows for Google Drive and OneDrive that work without a phone style browser, Shizuku support for TV, and custom cache limit settings suited to TV hardware.

The file server also works great on TV, meaning you can run an FTP or SFTP server from your Fire Stick and pull files from it on your PC over your local network.

File browsing and navigation
The main file browser supports dual pane mode through TwinWindow, which opens two folders side by side. Useful for moving files between locations without copying and then navigating separately. Available on both phone and TV.

Storage analysis
The storage analyzer gives you a breakdown of where your space is going. It finds large files, duplicates, junk, old files, and shows folder sizes. The duplicate finder works well, just go through the safety confirmation before bulk deleting anything as it is there to flag files that could be riskier to remove.

Encrypted vault
The vault uses AES-256 encryption. Pick a folder, set it up, and from then on those files are only accessible through the vault browser inside the app. There is no credential recovery by design so keep your details somewhere safe.

Network shares and cloud storage
Local network shares over SMB, FTP, and SFTP are all supported. For cloud you can connect Google Drive, Dropbox, OneDrive, WebDAV, and S3 compatible storage. The S3 setup lets you point the app at any S3 compatible endpoint, not just AWS. TV users get dedicated auth flows for Google Drive and OneDrive that do not require a standard browser.

Built in file server
You can run an FTP or SFTP server directly from your device, including from a Fire Stick or Android TV box. Start it from the server host screen, connect from your PC with any FTP client, and it stays running as a foreground service even when the screen is off. No cables needed.

Sync
Sync profiles let you keep two locations in sync on a schedule. Works across local storage and network locations, so keeping a folder mirrored to a NAS is straightforward. The scheduler runs it in the background without any manual input.

Media viewers
Images, video, audio, PDFs, text files, and ZIP and 7ZIP archives all open natively. There is an enhanced media player with a custom interface for video and audio. APNG animated images are supported too.

App management
Browse installed apps and install APK, XAPK, and APKS files through the built in package installer. The storage analyzer also includes debloat suggestions for identifying apps you may not need.

Shizuku support
Shizuku gives the app broader file access without full root. Works on both mobile and TV with separate setup screens for each. Once running, the app can reach parts of the filesystem that are otherwise restricted.

Remote management
Pair devices over WiFi for remote file management. ADB pairing is also supported. Once paired you get a full remote file interface over your local network. TV has its own dedicated pairing screen.

Search and indexing
Search runs off a background file index. Configure what gets indexed in settings under storage indexer. Once built, search is fast and supports filters. If results seem incomplete, check the index detail screen to see if indexing is still in progress.

Home screen widget
A bookmark widget lets you jump straight to your most used folders from the home screen. Set up your favorites in settings and they appear there automatically.

Bluetooth remote, your phone as a TV remote
This one surprises people. UFM Pro can turn your phone into a Bluetooth remote for your Android TV or Fire Stick, and it works across the entire TV, not just inside the app. Once connected, you can navigate the TV interface, control volume, and handle power from your phone. It is a proper system level remote, so you can use it in Netflix, YouTube, your TV launcher, wherever.

This is not a companion app gimmick. If you have ever lost your Fire Stick remote down the back of the couch you will immediately understand why having this built into a file manager app you already have installed is genuinely useful. Open UFM Pro on your phone, connect over Bluetooth, and you are controlling your TV.

If you have questions or something is not working as expected, post with as much detail as you can about your device, OS version, and what you were doing. The more context the easier it is to help.

The tip jar is in the supporter loyalty screen if you want to support development. Thanks for being here.

Thank You and Kind Regards

I wanted to share a project I recently started working on called Tend, an android app to help you automate the scheduling of your social life.

The idea originally came from a discussion on r/fossdroid about how hard it is to keep in touch with friends and extended family without relying on bloated, cloud-based business CRMs.

What it does

You can think of it as setting up cron jobs for your contacts.

• Contact Cards: Create dedicated profiles for people you want to keep up with (Name, notes, phone, socials, etc.).
• Custom Frequency: Set a "check-in" schedule (e.g., every 14 days, monthly, quarterly).
• Smart Reminders: The app will notify you when it's time to reach out.
• 100% Offline: Everything is stored locally on your device via SQLite/Room. No accounts, no telemetry, no cloud sync.

Since this is in the initial development phase, I’m looking for feedback on the features and the UI.

Repositories

GitHub: https://github.com/jksalcedo/tend

Codeberg: https://codeberg.org/jksalcedo/tend

I've wrote an app that strips EXIF metadata (GPS, camera make/model, timestamps) from photos before you share them — local-only, zero INTERNET permission. Just open-sourced it under GPLv3.

Source: https://github.com/themakoway/mako-scrubber

Exodus report: https://reports.exodus-privacy.eu.org/en/reports/com.mako.makoscrubber/latest/ (0 trackers)

Submitted to F-Droid (RFP) and IzzyOnDroid — both pending review. In the meantime the signed APK is attached to GitHub Releases, so it works with Obtainium today.

Happy to answer questions about the code or take feedback — first time open-sourcing something, so bear with me.

Hey everyone,

I love dark mode, but it drives me crazy when apps don't support it natively. Years ago, the go-to tool was DarQ (by KieronQuinn), but the original project was last updated in 2022 and just crashed on newer Android versions like Android 13/14 and the S24 series.

Since I wanted it for myself, I decided to fork it, modernize the code, and fix the crashes. I just released v2.2.3 which optimizes app loading and UI switches. No ads, no trackers, totally free and open-source.

App Name: DarQ (Revived Fork)

What it does: It lets you force dark mode on a per-app basis for Android 10 and above. It runs in the background using root or Shizuku, so you don't need any laggy accessibility services.

Key Features:

• Select exactly which apps run in force dark mode.
• Fully updated for Android 14/15 compatibility and bug fixes.
• Schedule system theme toggles based on sunset/sunrise.
