How it works

1. Snap a check-in

Take a quick progress photo — front and side, guided by an on-screen outline so your angles stay consistent.

2. Get your AI read

Your coach reads the photo in seconds: what's improving, your leanness/muscle/definition, and one thing to focus on this week.

3. Watch your arc

Compare any two moments, track your metrics over time, and keep your streak alive. See how far you've come.

Frequently asked questions

Is Fitness Journal free?

Yes. It's free to download — take your first progress photo and get an AI read in about 30 seconds.

What does the AI coach do?

After each check-in it reads your photo and tells you what's changing — leanness, muscle, and definition — compares it to earlier photos, and gives you one specific thing to focus on next.

Are my photos private?

Yes. Your photos are tied to an anonymous ID, never shared or sold, and used only to generate your private progress reads. Delete everything anytime from Settings.

How often should I check in?

One photo a week is enough to build a streak and see your arc. Add more whenever you want — daily, post-workout, or at milestones.
