✦ the difference

Bridging
the gap

Between a nail that almost fits and one that actually does. Precision sizing changes how your nails look, how long they last, and how confident you feel showing them off.

How it works

Three steps. About 30 seconds. Nails that actually fit, forever after.

01
Snap One Finger at a Time
Place each finger flat next to a quarter, nail facing up. The camera guides you through all five — the whole thing takes about 2 minutes.
02
The Scanner Does the Math
Computer vision uses the quarter as a real-world reference to calculate your exact nail width for every finger. More accurate than any tape measure, ruler, or guesswork.
03
Sizes Sent Instantly
Your complete size profile goes straight to your nail tech — no DMs, no typing, no guessing. Just press-ons that actually fit, every single time.

✦ why it matters

We do the hard work

so your nails don’t have to.

Forget ordering a cute set only to have half of them pop off by lunch. Five photos and a quarter is all it takes — your nail tech gets your exact sizes instantly, so you can focus on what actually matters: choosing your next lewk.
