Daily UI 001 Sign Up

I've decided to join the Daily UI challenge. I am spending no more than 1.5 hours each day (I'm a slow beginner, y'all) on each challenge. To make things fun, I'm creating a brand for each challenge.

Today's brand is cync. (an app that tracks your menstruation/ovulation cycle that can also double as a social network, maybe?) This app does not exist but I totally wish it did.
