Three ways to log without typing
Built for pin-loaded machines, dumbbells, and cardio dashboards alike.
Say it
"3 sets of 10 at 60 on chest press." Logged before you've wiped the seat. Voice or text, whatever's faster.
Snap it
New machine? Photograph the instruction placard and Spotter creates the exercise. Treadmill done? Snap the dashboard and the numbers are logged.
Ask it
"What did I do last time on triceps?" Date, sets, weight — and a nudge when the data says you're ready to move up.
Built in one day with Claude Fable 5. The whole app grew out of a blog post about tracking workouts by talking to an AI — and the build itself is documented, receipts and all.

Questions
Where does my data live?
Your workout log stays on your phone. Coach messages are processed by our server and Anthropic's Claude API only to generate the reply. No ads, no tracking, no data sales. Details in the privacy policy.
Do I need an Apple Watch?
No. The watch enriches cardio and heart-rate data if you have one, but voice and photo logging work with just an iPhone.
Is this medical advice?
No. Spotter is a logging assistant. Check with your doctor before starting a new exercise program.
Android?
iPhone first. If Spotter earns its keep there, the rest follows.
