Atreus is the training log for people who take the gym seriously: record every set in two taps and let the app handle the arithmetic, the progression and the memory.
🏋️ BUILT FOR THE GYM FLOOR
• Weight, reps and effort (RIR or RPE, your call) on a single row per set.
• See what you did last time and that exercise's history without leaving the session.
• Warm-up sets, drop sets, rest-pause and supersets.
• Rest timer with alert, plate calculator, a suggested warm-up ramp and one-tap exercise swaps.
• Weighted, bodyweight, assisted, timed and cardio: each mode asks only for what makes sense.
• Per-exercise notes: the seat hole, the bench height, whatever you keep forgetting.
📅 A PLAN THAT ADAPTS TO YOU
• Training blocks (mesocycles) for strength or hypertrophy, with accumulation, intensification and deload weeks.
• The app suggests weight and reps for every set based on your previous performance and the effort you logged.
• Readiness check-in: tell it how you slept and the session adjusts itself.
• Impossible day? Skip the session without polluting your history.
• Rather freestyle? Free mode rotates your own routines with no plan on top.
• 11 preset programs for 3, 4 and 5 days a week, each with a recommended level.
📚 167 EXERCISES WITH TECHNIQUE GUIDES
Every exercise ships a guide: muscles worked, biomechanics, setup, execution, grip, common mistakes and breathing. Plus a glossary for when someone drops "effective set" or "double progression".
📈 PROGRESS YOU CAN MEASURE
• Estimated 1RM, records per rep range and automatic PR detection.
• Monthly calendar, analytics per exercise, per muscle and overall.
• Weekly volume per muscle against its productive range, tonnage and estimated calories.
• Compare two blocks and see what actually changed between them.
🏃 CARDIO IN THE SAME SESSION
Treadmill, bike, elliptical, rower, stair climber or jump rope, with speed, incline, level and distance. Next to your lifting, not in another app.
📷 BODY TRACKING
Bodyweight, tape measurements and progress photos with a before/after comparator. Your photos stay on your phone.
👥 TRAIN WITH OTHERS
• A six-tier strength rank system, computed against your bodyweight.
• Friends, a leaderboard within your circle, achievements, avatars and an activity feed.
• Share routines with a link or publish them to the community catalog.
🔒 YOUR DATA, ON YOUR PHONE
• Works offline: everything is stored on the device and syncs when you have a connection.
• Backup, cloud restore and CSV export.
• Coming from another app? Import your history from a Strong, Hevy or FitNotes CSV.
• Home-screen widget and Health Connect sync.
• Your bodyweight and sex never leave the device.
🇬🇧 🇪🇸 English and Spanish, kg or lb, cm or in.
👑 ATREUS PRO (optional monthly subscription)
The core is free: logging, history, blocks, analytics, sync, friends, ranks and unlimited custom exercises. Pro adds the AI layer and the extras:
• Bring the routine you already train: paste the text or photograph it and the AI builds it for you.
• Let the AI design your whole training block around your equipment and your time.
• AI Coach: analysis of your progress and a chat for your questions.
• Weekly adjustment, a deload week built for you and a close read of one single lift.
• A substitute on the spot when the machine is taken or something hurts.
• Training watch: it tells you on its own when a lift stalls or a muscle drifts out of range.
• An automatic report every time a block closes, and goals with projection.
• Progress photo overlay, premium share cards, exclusive themes, colors and app icons, and a gold frame on your profile.
The subscription renews automatically and can be cancelled any time from Google Play.
