fiat mos - a habit tracker

Flossing is yes or no. Running is a number. A gym session is a whole page of its own.

Most habit trackers decide in advance how much detail a habit deserves. Fiat Mos lets you choose, one habit at a time:

• A tick, a number with a unit, a rating on a scale you invent, something you work through (books, repertoire, rolls of film), or a whole session with exercises, sets and weights.
• Missed something before midnight? Yesterday stays open, and in the morning the list shows what was left.
• A library for the things you work through. Each kind has its own unit, shelf, calendar and statistics, and each item shows how far in you are and how many more sittings it will take.
• Look up a book by its ISBN for title, author, pages and cover.
• Streaks, totals, medians and history are worked out from your entries every time and never stored.
• Undo writes a new entry instead of deleting one, and habits are archived, never erased.

Your data. Everything stays on the phone. There is no account and no telemetry. Two permissions: Documents, for Backup's readable JSON export, and Internet, for Look up only. Look up sends the book's ISBN, and nothing else, to the services you switch on: Open Library, Libris, the German and French national libraries, and Google Books if you allow it (off by default). Each service also sees your IP address. Nothing is sent until you press Look up.

The name. fiat — let there be. mos — custom, the way a thing is usually done; its plural, mores, is where morals come from.

Gutta cavat lapidem, non vi sed saepe cadendo. The drop hollows the stone, not by force but by falling often.

Part of the fiat family — small, focused Sailfish OS apps that do one thing plainly.
