Features
Everything you need to train consistently
From the first session to months later: fast logging at the gym, a plan that moves forward with you, and stats that actually help.
Rest timer
The timer starts after each set and tells you with sound and vibration when rest is over. Focus mode keeps the screen on.
Automatic progression
Owj reads your last session and suggests the next weight. You set the progression rule and the deload week.
Weekly plans
Put routines on weekdays or train them in rotation. Start from four ready plans (push/pull/legs, upper/lower, full body, 5×5) or answer a few questions to build one.
Records and one-rep max
Every new record gets celebrated. Estimated 1RM, the history of each exercise and its progress chart are always a tap away.
Muscle map and balance
See how many sets each muscle got, which ones are falling behind, and how balanced your strength is across the main lifts.
Weight, measurements, photos
Follow your weigh-ins on a curve with a goal, log body measurements, and compare before and after photos side by side.
A huge exercise library
Over 5,600 exercises with animations and instructions, filtered by muscle, type and the equipment your gym has. Add your own too.
Backup and import
Save everything to one backup file and restore it on another phone or browser. Bring your history from Strong, Hevy, FitNotes and Apple Health.
At the gym
Today's workout, without distractions
Start a session with one tap. Owj shows what you did last time, suggests today's weight, and starts the rest timer as you tick off each set.

- Barbell plate loading per side
- Log past workouts, add notes, move sessions
Progress
The numbers tell your story
A chart for every exercise, total volume, set counts and records, all from what you logged and never sent anywhere.
- Best set and estimated 1RM chart for every exercise
- Twelve-month activity calendar and weekly streaks
- PDF export of your plan and history, for print or your coach

A look inside

FAQ
Questions
Do I need an internet connection?
No. Logging, plans and stats all work offline. The only exception is each exercise's picture and animation, downloaded the first time you open that exercise and then kept on the device.
Where is my data stored?
Only on that device. Owj has no server and no accounts. To be safe, save a backup now and then from Settings → Data & backup.
Is there an iPhone version?
Yes, as a web app. Open app.owjfit.ir in Safari and choose Add to Home Screen from the Share menu. Owj lands on your home screen and opens offline after the first visit.
Can I move my data to another phone?
Yes. Tap Export backup on the old device and Import backup on the new one. The file is the same on Android, iPhone and the web.
I used another app before. Can I keep my history?
Yes. Owj reads exports from Strong, Hevy and FitNotes and weights from Apple Health, and matches the exercises to its own library.
Does it support pounds and a Gregorian calendar?
Yes. Language (Persian or English), weight unit (kg or lb), first day of the week and light or dark theme are all in Settings. In English, dates use the Gregorian calendar.
What data does Owj collect?
Nothing about your training or your body. The Android and iPhone apps send anonymous crash reports and basic usage counts (for example that a workout was started or finished) to help fix bugs, and you can turn this off in Settings. The web app sends nothing. Details are in the privacy policy.
