About Trainerrr

One place to plan, log, and understand your training.

Trainerrr is a fitness app for people who want to organize their workouts and follow their progress. Create training plans, run and log workout sessions, record nutrition, set activity targets, keep training notes and photo check-ins, and review your history week by week.

Optional connections to Apple Health or Health Connect import only the categories you pick. Trainerrr can also connect to compatible AI assistants through MCP, so you can manage your own training data by chatting.

Signing in with Google is optional. It uses only your basic account details, meaning your email address, name, and profile image, to create your account and personalize your profile. Nothing is sold or used for advertising.
