About Karui ToDo
An open source, privacy focussed, 120kB aesthetic Google Tasks alternative todo list app to quickly jot down things to do. Inspired by the system-24 theme and the Windows Mobile design system, this app's design is evolving into being even more eye-catching. It's also inspired by the functionality of f-droid app orgzly and simplicity of playstore apps like colornote and tries to be a better designed alternative to them.
This app never connects to the internet, you can setup sync to use Karui on other devices or alongside other markdown/text editors as the synced file is a markdown file. To use the widgets, first setup sync as the widget simply reads and writes to the markdown file, thus being energy efficient.
## Use it for
- Daily quick notetaking, calendar event marking
- Set reminders and use Karui like a habit tracker(BETA)
- Tasks list with percentage remaining metrics
- Taking notes from status bar or other app without switching to Karui or leaving opened app
- Taking design ideas when on youtube, instagram, snapchat, whatsapp, tiktok
- Capture passing thoughts when on a jog
- Journal events of your daily life on a separate tab, a daily log of activities
- Making bucket lists
- Playing quick mobile games (easter eggs)
- Use it like a password manager, save your passwords for quick access with copy paste at one place
## Features
- Simple note taking and list making with home screen widgets, status bar input, offline sync, recycle bin, drag-and-drop sorting.
- Bold New UI Design, leaning slightly more into windows-8 metro and windows mobile aesthetics with a mash up of retro terminalesque design inspired by Unix customizations found online.
- Lightweight: Consumes only 0.05% CPU and 128KB of RAM. After all, simple apps shouldn't need more—remember, the Apollo mission operated on a computer with around 4KB of RAM!
- Highly customizable: Offers many themes with option for custom fonts.
- To add a new note tab: use the `/TabName` format. Bringing some Linux Terminal vibes.
- To remove any tab (except the Main tab): use the `\TabName` format.
- Or just long-press any tab to rename, delete or add new tab (has a shadow that kinda brings back MS-DOS vibes)
- Support for custom fonts, so pick and select any .ttf files you like from your files system
- Add notes from status bar, or from other apps when selecting text (my mind races with ideas when watching youtube so I added this feature), helpful for saving trivial stuff you notice when reading some article or maybe for searching it later.
- Add a % symbol on any tabname and it automatically counts percentage of tasks completed
- Optionally disable screenshots for privacy when screensharing or in general
