trenOS

TrenOS is a training log built for people who actually lift and run — not a generic fitness app with a workout log bolted on.

WEEKLY SCHEDULE, NOT A CALENDAR Set your fixed weekly split (Push/Pull/Legs, Zone 2, intervals, long runs — whatever you run) and TrainOS tracks what's done, what's next, and what you're behind on.

STRENGTH + RUN LOGGING, ONE APP Log sets and reps or pace and distance in the same session. TrainOS auto-detects PRs against your history and shows your last numbers on every exercise so you always know what to beat.

MUSCLE RECOVERY MAP A front/back body map (male and female) shows what you've trained and how recently — tap any muscle to see which exercises hit it and when you last trained it.

STATS THAT MATTER Weekly volume, mileage, session streaks, and a recovery score — with week-over-week comparisons, not just raw numbers.

BODY TRACKING Log weight manually or connect a Bluetooth smart scale. Track measurements, BMI, and progress photos side by side over time.

NUTRITION, LOGGED YOUR WAY Quick-type a meal, scan a barcode, build a multi-item meal, or just talk — voice input parses what you say into a food log entry you review before saving. Calorie budget and macro breakdown update as you log.

AI COACH Ask questions and get answers grounded in your actual training data — not generic advice.

YOUR DATA, YOUR CHOICE Works fully offline with local storage. Sign in to sync across devices — your call.

No ads. No social feed. No streaks-shaming. Just your numbers, tracked precisely.
