The brief

Most fitness apps shout: streaks, badges, pop-ups. Katto Workout does the opposite. It shows one next step at a time, keeps the numbers to beat in every session, and works out the weekly check-in from your own logs, all on your phone, with no account and no tracking.

What we built

  • A daily loop: weigh in, warm up, train with the numbers to beat, log food as one total, say goodnight
  • A coach engine that adjusts targets and progression from your own logs, with tests in two time zones
  • Cycle care, warm-ups, cool-downs and a library of moves with videos
  • Pixel companions from Katto, who react to your day
  • Encrypted backup, invites and a signed update feed on Cloudflare
  • A Google Play build, approved for closed testing

Details worth noticing

Kindness

No streaks to break, nothing pops up, no ads.

Craft

Pixel art drawn to match Katto, from the night sky to the goldfish in the water jug.

Privacy

Logs stay on the phone; backups are encrypted.
