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 or in the app's private storage. 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, swipe between days
• Check and uncheck todos with a tap
• Each morning, carry over the todos left open on previous days, moved or copied
• Week review: todos done, still open or carried over, and the week's events
• Search across all days and notes, accents ignored
• Notes in folders, with search, rename, sharing and archiving
• Events imported from a shared calendar file (.ics), shared text saved as a note
• Home screen widget showing today's agenda and todos
• Reminders through local notifications, with an adjustable delay
• Safe with sync tools: changes made elsewhere are detected before saving, and conflict copies are reported
• Light and dark themes
• No account, no tracking, no network access
