Karui ToDo vs NerdCalci
Side-by-side comparison of two open source alternatives
Karui ToDo
An open source, privacy focussed, 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 set to evolve into something even more eye-catching. Features - Simple note taking and list making: Includes an undo delete feature. - 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. - 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.
