Everything you need to write about LeibFit is on this page: factsheet, screenshots at original resolution, app icon, contact. None of it needs a request — just take what you need.
Review codes for the full version are yours for the asking; a short mail is enough.
Inside the ZIP: every screenshot (German and English), the app icon at 1024 × 1024, and the factsheet as a text file.
Straight from the device, unscaled (1320 × 2868), nothing retouched. Clicking a tile downloads the original file. The same shots are available with a German and with an English interface.
The three numbers of the day: recovery, sleep, load — computed from the HRV, resting heart rate and sleep data of the watch you already wear.

Thirty days of recovery over time, measured against your own baseline — not against an average person.

"What lines up for you": links between your own behaviour and your numbers — statistically tested and explicitly labelled as correlation, not cause.

The suggested weight goes up — and the app says why in the same breath: every rep hit, recovery in the green. No adjustment happens silently.

After the session: sets, volume moved, and a comparison you can actually picture.
workout-summary.png
The weekly report sums up what the week actually added up to — sleep debt included, plus one sentence for the week ahead.

The coach answers on the device — through Apple's Foundation Models, not through a server.

What LeibFit is not
Not a medical device. The app detects no illnesses, makes no diagnoses and replaces no doctor. Recovery, sleep and load are orientation for training — measured against your own values from the past 30 days, not against a reference figure. If something about your numbers worries you, the right address is a medical practice.
Seven days free, no account — and no data ever leaves the device.
