you're being

Five things every other
AI fitness app got wrong.
Memory that survives.
Most "AI coaches" forget you after a week. LogBone stores every set, meal, and recovery metric in a structured database and feeds the relevant slice to your coach every time you talk.
The whole stack, not just sets.
Training, nutrition, sleep, HRV, supplements, skin protocol — one record. The coach reasons over the connections, not just the weight on the bar.
Honest about what it doesn't know.
The coach never invents workouts you didn't log. If the data is thin, it says so. If you describe a symptom, it refers you to a clinician.
Built for your wrist.
HealthKit and Health Connect feed the coach, and the Apple Watch companion streams your live heart rate mid-set. Your numbers stay on-device unless you log them yourself.
Your data, your device.
Token in Keychain, Face ID lock optional, no analytics SDKs, no advertising, no third-party tracking. The privacy policy is plain English.
Your coach, last Tuesday at 6:42am
Your last Push averaged RPE 8.5 across top sets, and your HRV is down 11ms versus your 14-day baseline. Drop top weight 2.5kg or hold and grind for one more session — your call. I'd hold.
The coach quoted real numbers because they're in your record. Generic AI can't do that. It doesn't have a record.
A logbook that earns its place.
Memory, real-data coaching, one unified record, instant macros, your morning brief, and a no-tracking promise.

Free on iOS and Android. Your training, recovery, and stack in one record — and a coach that reads it before it talks.
