The Fit Lens

Private beta

Your body is the scoreboard.

Food is primary. Training is the multiplier. The Fit Lens reads your body composition, not just scale weight, and tells you what actually changed: fat, muscle, and visceral fat, tracked separately.

Built for Android. Beta testing requires a Bluetooth body scale and body tape.

Body Score

One number that blends composition, activity, and sleep into a single read of the week. Not a mood ring, a weighted score you can trace back to what moved it.

3D body composition

Your scale readings mapped onto an annotated 3D model. Tap any region for the number behind it: fat, muscle, or visceral fat at that site.

GLP-1 dashboard

Weight and lean mass tracked side by side, dosed protocol overlaid. The question isn't whether the number is dropping, it's what kind of mass you're losing.

Food scanning

Barcode or food scale, logged in one step. Protein tracked against a target that adjusts as your weigh-ins come in, not a fixed number set once at onboarding.

Health report PDF

A clean export of your trends for a doctor's visit or your own records. A convenience tool, not a clinical document, built to be read in under a minute.

Before you sign up

Do I need special hardware?+

Yes. Body composition tracking requires a Bluetooth smart scale and a Bluetooth body tape, currently Etekcity and Renpho models. Without both, most of the app has nothing to read. See the beta signup page for details and where to get them.

Is it available on iOS?+

Not yet. The private beta is Android-only. iOS is planned for after beta.

Is this medical advice?+

No. The Fit Lens is an informational and tracking tool. It does not diagnose, treat, or replace guidance from a licensed healthcare provider. Full detail is in the Terms of Service.

What happens to my health data?+

It's used to run the Services you're using: tracking, coaching, and the features above. It is not sold. See the Privacy Policy for the full account of what's collected and why.
