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.

Remember: Notes & Reminders
APK
Remember is built around one simple idea: if you dismiss a reminder without finishing the task, it comes back. No important item disappears just because you accidentally swiped away a notification. Mark the note done, and the reminder is gone for good. ━━ 📌 REMINDERS THAT STICK ━━ Keep reminders visible until they are actually done. Choose from normal reminders, high-importance reminders with heads-up alerts, or a quiet summary notification that keeps overdue and upcoming items pinned in your notification shade. ━━ 🔔 NOTIFICATION ACTIONS ━━ Add useful one-tap actions directly to reminder notifications so you can act without opening the app: * Call, Message, or Email * Get Directions * Open a link, app, or shortcut * Copy text or Share content ━━ 💤 NATURAL SNOOZE PRESETS ━━ Snooze with human-friendly presets - soon, later today, this evening, and tomorrow morning - without hunting for the right time. ━━ 📅 RECURRING SCHEDULES ━━ Create daily, weekly, monthly, or yearly reminders. Remember also supports richer calendar-style patterns like "the last Friday of every month", with optional end dates or occurrence counts. ━━ 📝 MARKDOWN NOTES AND CHECKLISTS ━━ Write rich markdown notes with headings, bold, italics, underline, links, and code blocks. Build nested checklists for groceries, packing lists, project steps, or anything else that benefits from structure. ━━ 🔍 ORGANIZE AND FIND THINGS ━━ Use tags, stars, archive, trash, full-text search, filters, sorting, and bulk actions to keep your notes manageable. ━━ 📱 WIDGETS AND QUICK CAPTURE ━━ Home screen widgets for upcoming reminders, starred notes, and quick capture. A persistent notification can keep note creation one tap away at all times. ━━ ☁️ IMPORT FROM GOOGLE TASKS ━━ Move into Remember from Google Tasks using a connected account or a Google Takeout file. Import is read-only; Remember does not modify or delete your Google Tasks data. ━━ 💾 BACKUP AND RESTORE ━━ Export your notes and settings to a backup, optionally including attached media. Restore when moving to a new device, or import a backup to merge notes into your current collection. ━━ 🎨 MAKE IT YOURS ━━ Choose Material You wallpaper colors, hand-tuned color presets, your own custom colors, palette styles, gradient backgrounds, black OLED mode, cover images, and more. Theming is deep - the app can look and feel very different from any other notes app on your phone. ━━ 🔒 PRIVATE BY DEFAULT ━━ Your notes are stored on your device. There are no Remember servers, no account is required, and no data leaves your phone unless you export a backup yourself.

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!
