Frequently asked questions

Can I log workouts without internet?

Yes. Logging works with no signal, so a basement gym is fine. Ro, the other AI features and cloud sync need a connection.

What does the AI coach actually do?

Ro answers training questions, helps mid-workout (for example when you need an exercise swap), and builds a plan from your goal, schedule and equipment.

Is Buffro only for advanced lifters?

No. Beginners get guided plans and exercise demos. If you have lifted for years, logging is quick, and your ranks and history give you more to work with.

Can I track more than workouts?

Yes. You can track food, water, fasting, body measurements and recovery, and use your camera to scan meals or your physique.

Where can I use Buffro?

On iPhone and Android. Get it from the App Store or Google Play.

Is Buffro free?

Yes. Buffro is free to download and core workout tracking is free. Buffro Pro adds the advanced AI features, and the app marks which ones need Pro.

Get Buffro before your next workout.

It's free to download on iPhone and Android, and you can log your first workout in a few minutes.
