Workout

Weekly goal
A goal ring, a seven-day strip and a week streak on the first screen.
Up next
The template your rotation says comes next is listed first, with how long it usually takes.
Templates
Create, edit, duplicate and preview. Save any past workout as one, or update one with today's sets.
One reminder
Half an hour before you usually train, only on days when skipping would break your goal or streak.
Monthly recap
Workouts, time, volume, records and biggest one-rep-max gains, shown for the first week of each month.
Resume
A workout in progress comes back from anywhere, even after the app is killed.
The Workout tab: a weekly goal ring at one of five, a three week streak, and the Pull template marked Up next.

Live workout

Previous
Last time's matching set beside every row. Warm-ups pair with warm-ups. Tap it to copy.
Rest timer
Starts when you tick a set. Add or drop 15 seconds, or skip, in the app and from the notification.
Live records
A trophy on the set the moment you beat a record, and an outlined one on sets whose numbers would.
Rep targets
Double progression: one more rep each session, then more weight and the reps reset.
Reps left?
Optional reps in reserve after a working set. Easy sets make the next target jump twice as far.
Finish time
"Done ~7:40 PM", estimated from your usual pace per set, in the header and the notification.
Live Update
An ongoing notification with rest progress, what's up next and a Complete set button, promoted on Android 16.
Forgot to finish?
After an hour with no set ticked it asks "Still training?" and trims the idle time off the workout.
A live Pull workout: sets with previous numbers, outlined trophies on sets that would be records, and an estimated finish time.

Before you install

Is it really free?

Yes. There is no paid tier, no ads and no account. The code is on GitHub for anyone to read or build.

Why isn't it on Google Play?

It is one person's project and is shared as an APK from GitHub. The release is signed with a debug key for now, so Android or Play Protect may ask you to confirm the install. If you would rather not trust a download, build it from the source.

How do I install an APK?

Open the downloaded file on your phone. Android asks once whether your browser may install apps. Allow it, then tap Install.

Which phones does it run on?

Anything on Android 13 or newer. It is designed around Pixels: it takes its colours from your wallpaper, and the workout notification becomes a Live Update on Android 16.

Why is everything pink in the screenshots?

Because that is the wallpaper on the phone they were taken on. Stronger uses Material You, so on your phone it wears your colours.

Where does my data go?

Nowhere. The app has no internet permission. Your log lives on your phone, Health Connect sync is optional, and backups are a JSON file you keep.

Is this made by the Strong team?

No. Stronger is an independent app made by someone who likes how Strong works. It reads Strong's CSV export and nothing else of theirs.

Does it work in pounds?

Yes. Pick kg or lb in Settings, along with your bar weight and the plates your gym has, and the plate calculator follows.
