Gym Boss is the training notebook that learns how you train.
Plan workouts your way with flexible notes, then use Train Mode when it’s time to lift. Track sets, cardio, nutrition, bodyweight, and progress without forcing your routine into someone else’s template.
As your training history grows, Gym Boss can help you understand it, recommend what to do next, and give you an AI coach that already knows the context behind your workouts.
WORKOUTS THAT FIT YOU

Choose from built-in training splits or start blank
Use Train Mode to execute your workout
Track workout duration and exercise history

ASK GYM BOSS AI
Ask questions about your workouts, progression, nutrition, and training. Gym Boss can use your recent history and workout context so you don’t have to explain everything from scratch.
TRACK MORE THAN LIFTS

GYM BOSS PREMIUM
Premium turns your training history into deeper guidance with expanded AI coaching, personalized training intelligence, advanced insights, and additional Premium features.
The core tracking tools stay useful without Premium. Gym Boss is built so the data you log belongs to your training experience, not a paywall.

Estimate meals from photos
Premium members can now photograph a meal and receive estimated calories, protein, carbohydrates, and fat. Every estimate can be reviewed and edited before anything is saved. Before-and-after photos can estimate only what was eaten.
The muscle body map now follows your selected color theme in both light and dark mode.
Workout notes are now more responsive and reliable, with stronger protection for edits during interruptions or poor connections.
This update also improves subscription restoration, Premium status synchronization, account deletion, accessibility, and overall stability.
