AI Coach

Your coach remembers every set.

It reads everything you log, briefs you before each session and debriefs you after. Stall on bench and it knows, because it has your numbers, not a guess.

Pre-workout brief

Easy usage and beginner friendly with AI

“I've been using RepEight for a while and it's easily one of the best gym apps I've tried. The workouts are smartly personalised based on your goals and available equipment, and the AI is extremely helpful when you feel lost at the gym. The interface is super clean, easy to use, and the tracking features make it really satisfying to see progress and keeping you going with your fitness journey.”

Frequently asked questions

What is RepEight?

RepEight is a workout tracker for iPhone, Apple Watch and Android with an AI coach that remembers how you train, a muscle heatmap, and a friends feed with leaderboards. It has 1,400+ exercises with demos, 27 official programs, and works offline.

Is RepEight free?

Yes, RepEight is free to download and you can log workouts, track PRs, follow programs and use the friends feed without paying. Free accounts get 20 AI coach messages a day and 3 AI workouts a week. RepEight Pro (£3.99/month) makes both unlimited and adds unlimited routines and custom exercises.

How is the RepEight AI coach different from ChatGPT?

ChatGPT only knows what you tell it in a chat. RepEight’s coach reads your logged workouts, PRs and weekly consistency, so its advice is based on what you’ve actually done. It briefs you before each session and debriefs you after.

Does RepEight work on Android and Apple Watch?

Yes. RepEight is on iPhone and Android, with an Apple Watch app, Live Activities and Home Screen widgets on iOS.

Can I train with friends on RepEight?

Yes. Follow friends, react and comment on their workouts, see where you rank on friend leaderboards, and compare your training head-to-head.

Yes. There are 27 official programs (strength, bodybuilding, hybrid, cardio, mobility and yoga) and 57 single-workout templates, or the AI coach can generate a workout for you.
