Four meaningful upgrades for serious lifters who want more depth.
After every workout, your AI coach reviews your session and gives personalized insights — what went well, what to adjust, and how to improve next time. Only available in Pro.
Deep analytics across your training history — volume trends, muscle group breakdowns, PR progression charts, and more. Understand exactly how your training is evolving.
The free tier supports up to 3 saved workout templates. With Pro, there's no limit — build as many programs, routines, and templates as you want.
See exactly which plates to load on a visual barbell diagram. Free tier shows text only. Pro gives you the full visual layout so there's no guesswork at the rack.
You don't need Pro to have a great experience. Everything below is free, forever, with no ads.
