PalmTan

PalmTan helps you tan your palms by notifying you whenever they fall to their natural downward position and dont face the sun anymore.

Simply open PalmTan on Apple Watch and orient your palms toward the sun. Then tap Start! Youll be alerted whenever your palms dont face the sun anymore.

All of your data is synced with PalmTan on iPhone, where you can view and manage all of your sessions.
