INSIDE FITTSO

One place for everything
your body is telling you

FITTSO is built for the phone. The web view mirrors what reads well on a large screen — logging, capture and device pairing stay in the app.

  • Your feedThe people you train with, what they logged, and what they're working toward. Nothing is public by default.
  • FITTSCOREFITTSO's own reading of where you are — computed from your data, not borrowed from a device maker.
  • MacroSnapPhotograph a meal and get the macros back. No weighing, no searching a database.
  • Wearables and scaleConnect a band, a ring or a Bluetooth scale. Every reading is labelled with where it came from.
  • Check-in and mappingLog where you trained and who you trained with, at the level of detail you choose.

WHERE YOUR DATA COMES FROM

Connected sources

You choose each one, one at a time, and you can disconnect any of them whenever you want. Disconnecting stops the sync and removes that source's data.

Data from a connected device is labelled with its source everywhere it appears. It is used to show you your own information and to compute your FITTSCORE. It is not sold, not shared with advertisers, and not used to train models across users unless you separately opt in — and data from some device partners is never used for training at all, regardless of what you opt into.
