Instant nail sizing for press-on artists
SizeKit is built and we're in the final stretch — polishing the experience, fine-tuning accuracy, making sure everything feels right. The app is going to keep getting better over time, but it's ready for you to start using on December 19th.
Why founding members?
We wanted to open this up early to people who are excited about what we're building — people who will use it, give us feedback, and help shape what comes next. Your support at this stage means we can stay independent and keep building what the community actually needs.
In return, you get our best price locked in forever, early access before anyone else, and a direct line to the team. We're building this for you — it only makes sense you'd be the first to use it.
Customer sized in minutes, not weeks.
Share your unique SizeKit link with your customer via text, DM, or email.
Your customer places a reference object next to their hand and scans each finger. Only takes minutes.
Using geometry and precise calculations, we convert their measurements to the nail brand you use.
The sizes go straight to your dashboard and you're notified instantly. Ready to create their set.
Instead of waiting a week for a sizing kit to arrive, your customer is sized within minutes of placing their order.
This isn't just a discount. It's a partnership.
Be among the first to use SizeKit. Before anyone else.
When prices go up at public launch, yours stays the same. Always.
Your feedback shapes what we build next. Feature requests, bug reports, ideas — we're listening.
Unlimited sizing links, artist dashboard, saved measurements — everything SizeKit offers.
When we roll out updates and new features, founding members get them first — before anyone else.
You're not just a customer — you're one of the first users. Your feedback shapes what comes next.
We're committed to making something that nail artists and their customers actually love to use. Something accurate. Something easy. Something that keeps getting better.
