trenOS
The readout not the motivation
Free · Designed for iPad. Not verified for macOS.
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.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Sleep now has its own home. Set a bedtime and a wake alarm, and TrenOS rings full-screen even when the app is closed — snooze, dismiss, or start the night right from the alert. Your recovery score now factors in how you actually slept.
Supplements got quicker and quieter, with reminders: pick which times of day to get a nudge for each one, add from a photo or by hand, and the shelf shows what's running low without you asking.
Ask the coach for a program built around a real goal — set your race or target date and it proposes a week you can adjust before starting.
