About
Add gloss to the nails only. Even out the skin only. Blur the background only.
A photo editor for nail work, built by a working salon owner.
For salon shots and for keeping track of your own nails alike.
FEATURES
• Automatic AI separation
A hybrid of Apple Vision and our own Core ML model separates nails, skin and background for you.
Straight after the shot, every layer is ready to edit on its own.
• Never lose a pixel of the nail
The gloss, texture and color of the nail are fully protected.
Smoothing and blur are applied to skin and background only.
• Full resolution, start to finish
Edit and export 4000×3000 images with no downscaling.
Photos are saved back to your library at their original quality.
• An editor that keeps up with you
Four tabs — Nails, Skin, Background and All — each with its own set of effects.
Dial in the amount and see it update instantly.

Every photo is processed on your device. Nothing is ever uploaded to a server.
