WHY LIFTERS USE ATLAS
• Gamified progress. Earn XP per muscle, climb 100 levels, and unlock new tier materials as you go.
• Your 3D muscle atlas. Watch the muscles you train heat up and gradually recover, so your training balance is obvious at a glance.
• Automatic PRs. Atlas tracks your estimated 1-rep max and catches new personal records as you log them.
• Recap cards. Finish a session and share a clean recap of your volume, sets, XP, and PRs.
• Built-in rest timer. Stay on pace between sets with fast, simple adjustments.
ON YOUR WRIST (WEAR OS)
• Log from your watch. Pick today's routine, dial in weight with the rotary crown, log every set, and run your rest timer without reaching for your phone.
• Heart rate and calories tracked through your session, then your finished workout is written to Health Connect.
• Start on your phone and carry on from your watch, or the reverse. Atlas keeps the live session synced.
• A Wear OS tile and a watch-face complication keep today's workout one tap away.
TRAINING THAT FITS YOU
• Build your own routines and splits, or skip the structure and train freestyle.
• Works offline. Log anywhere, and Atlas syncs when you are back online.
• Pick your accent colour and carry it across Atlas on both phone and watch.
Atlas is free to start and includes the first 10 levels. Premium is free for 14 days, then a subscription keeps the full climb, cross-device sync, and the rest of the premium features.
