Calibration controls
Dark-spot detection mode Raw counts any darkening as a spot, including lighting shadows — the pre-2026-08-10 behaviour. Shadow-corrected removes smooth lighting gradients, what the live app scores with now, but can suppress real spots when acne is dense (found 2026-08-12: a face with visible widespread acne scored green). Blended only discounts darkening shaped like a smooth gradient, so dense real acne survives while lighting shadows still get removed — not yet shipped. Acne and Flek hitam only.
Compare photos side by side

Load the same face under several lightings; the spread column is max minus min, the number this project has always calibrated against.

Fine tuning

If a concern reads too high or too low on a face you can judge by eye, nudge it here. Units are score points, so −12 means "this should read 12 lower".

Nothing here can change the app; export copies the equivalent norm() windows for you to paste by hand.
