How it works
- Tap the mic. Open Strongbro and tap the mic button at the bottom of the Home screen.
- Say your workout. Talk like you would to a training partner: “Bench press, 3 sets of 10 at 80, then squats, 5 by 5 at 100.” Any language, any gym slang.
- Review and done. Strongbro maps what you said to real exercises, sets and weights. Check the numbers, tap Done, and the session is logged.
One month, three honest answers.
Your volume for the month against the last one, which muscle groups moved and which quietly stopped, and the heaviest lift you hit. Each number comes with what it was before.

Which muscles got the work.
A ring for the month split by muscle group, with the totals written out underneath. Useful mainly for finding out that you train legs less often than you thought.

Ranks earned by showing up.
Fourteen ranks, from Fresh Meat to Bro God, counted in sessions logged. How much you lift makes no difference. The ladder shows where you are and how many sessions the next rank takes.

Weight, read as a curve.
A weigh-in is a number and a tap. Your weight swings by a kilo between mornings for reasons that have nothing to do with training, so the screen shows the trend and the distance left to your target.

Frequently asked questions
How does voice workout logging work?
You tap the mic and describe the session in your own words. Strongbro transcribes the audio, maps exercise names in over 30 languages to its catalog, converts spoken weights — including plate slang like “two plates” — and writes each set to your log. You review everything before it saves.
Is Strongbro free?
Strongbro has a free 3-day trial with everything unlocked. After that it is $14.99 a year, or $19.99 once for lifetime access. There are no ads and no locked-away data.
Does Strongbro work offline?
Manual logging, records, ranks and insights all work offline. Voice logging and the physique scan need a connection because the audio and photo are processed by an AI model.
What is the physique scan?
You take or pick one photo and Strongbro's AI scores your physique overall and per body part, with short notes on strong points and what to train. Scores are stored on your device so you can watch the trend.
Which languages can I log in?
The app interface ships in 31 languages, and voice logging understands workout descriptions in any major language — including gym slang in English, German, French, Spanish, Portuguese, Italian, Russian and Bulgarian.
Where is my workout data stored?
On your iPhone, with optional iCloud sync to your own Apple account. There is no Strongbro account and no server-side database of your training history.
Does it track personal records automatically?
Yes. Every set is checked against your history, and weight-at-reps plus estimated one-rep-max records update themselves. Records are grouped by month so you can see the best lift per exercise.
