Real analyzer, real result screen. Nothing here touches the live app.

Calibration controls

Fix shadow false-positives Measures dark spots after removing the lighting gradient, so a shadow stops counting as spots. Changes acne and dark spots only. Camera resolution Analyse at 512px like a real camera scan, instead of 1280px like an upload.

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.
