Strength + running · Offline-first
The readout, not the motivation.
Lifts and runs on one calendar. See what you completed, what you missed, and how recovered you are, with PRs, e1RM and pace worked out on their own. No feed, no badges, no encouragement you didn't ask for.
Free on iPhone · Android in testing
Five screens. Lifts and runs, one split.
Today
Beat your numbers.
Your fixed weekly split, front and center. See what's done, what's next, and the exact weight and reps from last time on every lift, so you know what to load before you touch the bar.
Plan
Your week, mapped.
Lifts and runs on one month view, built around your recurring split. Tap any day to see what was scheduled, what got done, and what you missed.
Stats
Progress, measured.
Weekly volume, mileage, and a recovery score that reads last night's sleep, each compared against last week rather than drawn as a vague trend line. Estimated 1RM per lift, with stalls flagged.
Muscles
Know what you actually trained.
A front and back recovery map by muscle group, colored by days since last trained. Built for people who program their own splits and want the data to prove it.
History
Lifts and runs, one log.
Every session in one list: pace and distance on the runs, lifts and volume on the strength days, duration and calories on both. Filter to one day type when you want a single thread.
Offline means offline.
A 3,000 entry food database ships inside the app, over a thousand of them Indian dishes. Search it on a flight, in a basement gym, on airplane mode. Calories, macros, and micronutrients resolve without a request leaving your phone.
Sessions, weight, and history behave the same way. Every entry writes locally first and syncs later, so nothing you log is waiting on a signal bar.
Food and coaching, both built on data you own.
Nutrition
Photograph the plate, scan a barcode, or type it. Calorie budget, macros, and micronutrients (sodium, calcium, iron, vitamin C, folate) update as you go.
When a search genuinely matches more than one food, the app says so instead of picking for you. Raw or cooked, skinless or with skin: you choose, because the difference is worth about 30% of the protein figure.
Coach
The coach reads what you logged, not what you named things. It works out what each day actually trains from the exercises in it, so a day called "Full Body" that only ever logs pull work is treated as pull work.
It tracks estimated 1RM per lift and flags stalls, tells you how long it has been since your last PR on anything, and shows how many of your scheduled sessions you actually completed. Give it a race or a target date and it proposes a program you can adjust before you start.
We built TrenOS for people who already know how to program their own training.
TrenOS is not a coach. It doesn't tell you what to lift or when to rest. It measures what you actually did and gets out of the way.
Who it's for
Advanced trainees who self-program: Push/Pull/Legs splits, Zone 2 and interval running, periodization, RIR, volume landmarks. If you understand those terms already, TrenOS won't explain them back to you.
What it isn't
Not a social platform. Not a coaching app that programs sessions for you. Not built around motivation, because motivation isn't the thing we measure. Execution is.

Questions people actually ask.
Do I need an account to use it?
No. Every mutation persists locally first. Sign in with email only when you want your data synced across devices.
Is there an Android app?
It's in testing now. Until it reaches the Play Store, the web app installs to your home screen and works offline. The Android form at the bottom of the page is how you hear about launch day.
