Private by design

Your numbers never
leave your phone.

No account to make, no server to trust. Everything stays on your device and syncs through your own iCloud, so even I can’t see what you lift.

Made by one person

I built Spotter because I wanted a strength tracker that was fast, private, and actually felt like it belonged on iPhone. No account, no data sold, no ads. Just a tool I use every single time I train.
