toodoo
APK
Features of toodoo Tasks: You can create, change and delete tasks. Each task has a name, a category, a priority (HIGH, MEDIUM, or LOW), and a completion-status (i.e. it is either OPEN or DONE). Optionally, each task can also have a description (arbitrary text), a due_date and a due_time. In order to avoid unintentional deletion, a task can only be deleted if it is DONE. Categories: You can create as many categories as you need. The category a task belongs to can be changed. A category can be renamed. This will affect all tasks that belong to that category. Unused categories can be deleted. I.e. deletion is only possible if the category has no tasks, and if it is not used in the current filter. Filtering tasks: It is possible to restrict the tasks displayed in the list, e.g. completed tasks only, or tasks with low priority only, etc. In general, the tasks to be displayed in the list can be filtered by * completion_status * due_date/due_time * priority * category or any combination of these. For due_date there are several predefined filter options, e.g. TODAY, CURRENT_WEEK, OVERDUE, TASKS_WITHOUT_DATE, etc. For priority and category, it is possible to filter with more than one option. E.g. you can choose to show tasks with priorities HIGH or MEDIUM. Or you can display all tasks that have either category "Family" or "Friends". Sorting tasks: The task list can be sorted by: * completion_status * due_date/due_time * priority * category * name Any sort order is possible. E.g. first by due_date/time, then by completion status, category, priority and name. Or any other order you prefer. Searching tasks: Tasks can be searched by text. The search text you enter can be applied to the task name, the task description, or both. Case-sensitive search is possible. In the list of search results, when displaying details of a task, the search string is highlighted in the task name and / or description. Convenience: There are shortcuts for often used actions. E.g. * From the context menu of a category you can jump to a list of all tasks for that category. * From the context menu of a task you can change its completion_status, set it to DONE (or OPEN respectively), or set its due date to today or tomorrow. * When the task list is filtered by "tasks due TODAY", you can easily move to the previous / next day by swiping right / left. * Similarly, by swiping you can easily move to the previous / next week (when the task list is filtered by "tasks due CURRENT_WEEK"), or to the previous / next category (when all tasks for a category are displayed). Display: Tasks due in the past, today, or in the future have different background colors, so they are easily discernible. The color scheme adapts to the display mode of the underlying android. I.e. if dark mode is selected (provided your android does support dark mode), a dark color scheme is used also for toodoo. Import / Export: All user data (i.e. tasks, categories, filters and sort criteria) can be exported to an external file (xml-format). Vice versa, data can be imported from an external file. Technical: Your data is stored locally on your device. No connection to the internet needed. No ads. No tracking. Restrictions toodoo is minimalistic. It focuses on managing, categorizing, filtering, and sorting tasks (however, more features may be added in future releases.) Thus, there are some restriction, i.e.: * The user interface is in English only. * Name of folder and file for export data are fixed (i.e. /Download/toodoo/toodooData-yyyy-mm-dd-hh-mm-ss) * Settings are currently fixed, e.g. - date format is yyyy-mm-dd, time format is 24 hours. - first day of week is Monday. - within a day, tasks without due_time are sorted behind tasks with due_time.

xnotes
APK
xnotes is a handwriting-first notebook for phones and tablets, built for pen and stylus. Write, sketch and annotate with pressure-sensitive, variable-width ink, and nothing you draw is ever flattened. Highlights: * Pressure-sensitive ink: a custom stroke engine turns raw stylus samples into a smooth, variable-width ribbon that swells and tapers with pen pressure, so handwriting and sketches feel natural instead of like a flat marker. * Live presentation streaming: broadcast your canvas to any web browser on the same network in real time. Turn a tablet into a wireless whiteboard for the room, with nothing to install on the other end. * Vector PDF, in and out: drop in a PDF as a page background to annotate, then export your notes back to PDF as true vector — ink and text stay crisp at any zoom instead of being flattened to pixels. * Razor-sharp deep zoom: a background renderer redraws a high-resolution viewport off the main thread, so you can zoom far in and the ink stays sharp rather than turning blocky. * Real highlighter blending: highlighters are composited live every frame with a true multiply blend, so overlapping strokes deepen like real ink instead of painting over one another. * Neon pen: a glowing pen with a bright white core and saturated, luminous edges for accents that pop off the page. * Smart PDF dark mode: invert a PDF page for comfortable night reading while leaving embedded photos and images untouched. * Nothing is ever flattened: every stroke is stored as editable vector data in the open .xnote format, so you can re-select, move, restyle or erase any mark at any time. * Stylus-aware by design: pen and finger are handled separately, so you can pan with a finger while you draw with the pen; on devices without a stylus, finger drawing turns on automatically. * Private and open: open source, no accounts, no telemetry. Files go through Android's Storage Access Framework, so the app needs no broad storage permission (network access exists only for the optional presentation server). Also includes: * Shapes, text boxes and image insertion * Stroke and object erasers, plus box and lasso selection with move and resize * Multi-page documents with several page sizes * A backstage file area: recent notes, a built-in folder explorer and quick sharing * A side panel with page thumbnails, contents and bookmarks * Undo and redo * Pinch to zoom and a configurable pen side-button action * Customisable theme, accent colour and page defaults

TeXeTeScribe
APK
TeXeTeScribe provides what default Android lacks: read and edit text-based files. It also implements concept of a folder with a notebook functionality. 📖 You data is always readable. If a platform can display characters, it can handle a TXT file: Android, iOS, Windows, Linux, macOS, ChromeOS, Smart TVs, e-readers, gaming consoles, embedded and IoT devices, cloud storage and collaboration tools (Google Drive, iCloud, Dropbox, etc). TXT files are the most universal format because every operating system "understands" them. Text files avoid compatibility issues of proprietary formats, ensuring flawless transfer across devices and platforms. 🛡 Future proof your content. Text files are universal and future-proof, free from the compatibility problems that plague proprietary note formats. You don't need a specific app to access TXT file. It can be viewed and edited on basically everything with a processor. 🔓 Notes in TXT files never get trapped. Most note-taking apps store data inside private app databases or proprietary cloud formats. If the app stops working from a bad update or glitch, or disappears from the app store, your notes often go with it. Unreadable, unexportable, and locked behind a backup you cannot open. Plain .txt files avoid all of that. 💾 Notes survive phone failures. When data is stored in internal memory, Android encrypts it by default, starting 2015. If the system glitches after an update, or the phone can't run its OS, all data in phone's internal memory becomes unaccessible, and basically lost - often Android repair process implies wiping all data. Saving notes on a microSD card keeps them physically separate from the system. Just insert SD card into any other device: files stay fully accessible in any file manager. 🔠 Text always looks readable. Every text file has its own encoding. Android uses UTF-8 by default, Windows often saves text in ANSI (Windows-1251), old DOS programs use CP866, and classic macOS systems relied on MacRoman. There is also UTF-32, used in some technical files. Most Android apps simply assume everything is UTF-8, which is why older documents or foreign-language text often appear as unreadable gibberish. TeXeTeScribe app automatically detects the correct encoding, and shows the text readably. 👁 See what’s inside before opening. App shows list of files beyond simple filenames. You get short content previews of each file and its modification time. This lets you instantly recognize which note or document you need without wasting time opening files one by one. 💡 Your latest thoughts stay on top. Typical note apps mix your notes together alphabetically or by title, making yesterday’s idea vanish in the pile. TeXeTeScribe reflects how real note-taking works: what you just wrote is what you are most likely to continue developing. The notes you worked on most recently stay right at the top, so you can continue writing or reviewing without searching. 🛠 Open almost any text-based file. TeXeTeScribe recognizes and edits many everyday formats: .txt, .md, .json, .xml, .csv, .html, .log, .yaml, .cfg, and more. It saves time when you just need to read or fix a file, without searching for a different tool. 🛰 Work offline forever. Because everything is stored locally, the app works without a connection. Your notes, configuration files, and logs are always available, even on airplanes or in areas without service. TeXeTeScribe lets you create, read, and edit plain text notes that remain fully accessible and compatible across all devices and platforms. Your data stays future-proof, portable, and never locked inside proprietary formats or apps. Created by Eugen Barilyuk EB43 https://eb43.github.io
