Rank-My-Favs
APK
Do you keep lists of your favorite things, such as movies, books, recipes, or music albums? You might keep list(s) that looks like this: Network (1976) Lone Star (1996) Devils (1971) The Seventh Seal (1957) ... Many more films_h But how do you rank these? You might be tempted to order them by preference, but this could quickly get overwhelming for long lists. A much easier method is to use pairwise comparisons, which shows you single head-to-head pairs, and has you choose which one you like best. After doing a small number of these matchups, Rank-My-Favs can confidently create a ranked list for you. Under the hood, Rank-My-Favs can sort by either the win-rate, or the more advanced Glicko rating system.

SDB Viewer
APK
This app can display the data produced and managed by Song Database if the file is accessible via URL (web address). It cannot be used for anything else, so if you don't use Song Database, this app isn't meant for you! You can view the song lyrics, any available translation and the guitar chords (if available). Translation and chords can be disabled in the settings. The app keeps a local version of the data until it can fetch an update (after a timeout which is three days by default) so you can use it offline as well. If you are the administrator of your Song Database installation and don't want to upload the file containing the songs every time you modify it, you could set up a synchronisation solution like Nextcloud and use the "share link" functionality - the resulting link has to be used in the app. In case you don't want to force all users to enter the link manually: The app can be configured by scanning a QR code. For more information on that, see the homepage.

Saber
APK
Saber is the notes app built for handwriting. It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly. Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss. Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own! The app is completely open-source so that anyone can view the source code and see exactly what it's doing and how it handles your data. Many other note-taking apps are closed-source and proprietary, meaning that their inner workings are a mystery to the public. As someone who studies maths, highlighting multi-line equations was always a hassle with other apps, where the highlighter would change color when it overlapped with itself. Another problem I had was that in some apps, the highlighter would render on top of the text, fading it out and making it hard to read. Saber's highlighter has no such issues. It utilizes canvas compositing to render the highlighter in a way that is consistent with/better than traditional paper, where it handles overlaps and maintains color consistency. Saber has everything you need to keep your notes organized. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. And even though a note may be buried deep within a nested folder, you can still access it easily with your most recent notes always available on the home screen. Discover a whole new way to capture and organize your thoughts with Saber. Whether you're a student, professional, or creative mind, Saber is your trusted companion for digital handwriting. Download now and let your ideas flow freely!

Safe Notes - Encrypted Notepad
APK
★ Safe Notes is an open-source project that aims to provide an encrypted, private note manager. ★ Employs rigorously tested AES-256 encryption standards to encrypt your notes. ★ Incognito Keyboard ★ Brute-force protection ★ Protection against data snooping via adb ★ Android background snapshot protection ★ Inactivity guard ★ Automated encrypted backup ★ Arctic Nord style dark and light theme ★ Customization for colorful notes ★ Seamless migration to new device. Use the backup to move your data from one device to another device. ★ Safe Notes provides ultimate security - you don't have to trust us, or any other third party because everything is done locally on your phone. ★ Contrary to the ongoing frenzy of "move everything to cloud" we believe in "localization of user data" giving you the control of your data and not some third-party cloud service provider. ★ Completely anonymous, no inbound and outbound requests. --- How it works --- ★ Safe Notes encrypt each note with a unique AES-256 symmetric key derived from your passphrase and randomly generated salt. ★ If an attacker tries to brute-force your encrypted notes it will take "Trillions Upon Trillions years" in contrast, the universe has only existed for 15 billion years. (You must use strong and long passphrase). ★ AES-256 is symmetric key encryption that is quantum-resistant, i.e. it isn't vulnerable to quantum computers. ★ Everything is stored locally on the user's device. ★ Your passphrase is never stored on the device, it gets purged as soon as you exit the app. ★ We can't decrypt your notes even if we wanted to. That gives you the ultimate security, but it also means that a lost passphrase can never be recovered. ★ Safe Notes is an open-source, not-for-profit project.
