What makes us different
The app is built around decisions, not decoration.

Basic logging is free
Friends can join, browse lifts, and log simple sets without hitting the paywall immediately.
Pro adapts the plan
Paid users unlock adaptive sessions, progress views, recovery, equipment logic, and deeper personalization.
India + global
INR pricing, 9 languages, and gym-equipment assumptions that fit real training environments.

Powered by Claude
A coach who actually reads your training log.
FitRox's coach is built on Anthropic Claude. It sees your last six weeks of sets, RPE, recovery, and biometrics — and responds in plain language, not generic templates.
- Reads your session history before answering
- Suggests deloads, intensity changes, or substitutions
- Explains the "why" behind every recommendation

Bench stalled at 80kg × 4.
Three weeks at the same weight is plateau territory. Drop to 70kg × 8 today, RPE 7. Rebuild rep capacity, then push intensity Friday.
Got it. Anything to watch?
Keep elbows tucked at 60° on the descent — your last log mentioned shoulder tightness. Pause 1s at the chest.
