PlaneTxt

PlaneTxt is an opinionated, future-proof app to manage your life in plain text: todo, agenda, journal and notes.

Everything is stored as Markdown files in a folder you choose. One daily file per day holds your journal, todos and events; notes live in subfolders. There is no database and no lock-in: sync the folder with Syncthing, Dropbox or anything else, and edit the files with any text editor.

Features:

- Month calendar with the Markdown content of the selected day below it

- Check and uncheck todos with a tap

- Refill: carry unfinished todos over to today

- Notes browser with search and rename

- Home screen widget showing today's agenda and todos

- Reminders through local notifications

- Light and dark themes

- No account, no tracking, no network access
