Your progress, in pictures

Change you can
see.

Day to day, change can be hard to notice. Keep your progress photos together and look back at where you started.

Your photos tell the story. Body-fat estimates and weight tracking add context along the way.

Know what
to expect.

How does the body-fat estimate work?

Add 1–3 photos in the app to get an AI estimate and physique analysis. Results are estimates for fitness tracking, not clinical measurements. Lighting, pose and photo quality can affect them.

How should I take progress photos?

Use similar lighting, distance and poses each time. Add front, side and back photos when possible, so your history is easier to follow.

Can I track more than body fat?

Yes. BuffMeter also includes weight tracking, progress charts, physique analysis, BMI in your profile, goals and daily check-ins.

Is BuffMeter free?

BuffMeter has free and Pro options. Some features have usage limits; the app shows your available uses and subscription options before you upgrade.
