What the app does

Two-photo analysis

A wrist shot for undertone and a face shot for hue and depth. The app checks each photo for lighting and focus before it reads anything.

Palettes you can act on

Safe, flattering, and avoid colors for five occasions — everyday, travel, work, date night, and festive — plus lipstick, blush, and hair shades.

Check clothes you already own

Photograph a garment and ToneFit extracts its dominant color, grades the match against your palette, and suggests how to make it work.

Works with no connection

There is no server and no account. Every calculation runs on your iPhone, which is also why the app has nothing to send anywhere.

Privacy at a glance

ToneFit contains no analytics, no advertising, and no third-party SDKs. It never connects to a network, so there is no path for your data to reach us even in principle. Only structured results are saved — your undertone conclusion, garment matches, and saved colors — never the photos themselves.

Settings lets you export everything as a JSON file you keep, or permanently erase all of it.

App legal documents

These cover the ToneFit mobile app. The UndertoneOnline website has its own privacy policy and terms of service, because the site — unlike the app — uses analytics and cookies.
