eluna: Period & Cycle Tracker

made by a couple, for couples.. eluna learns your body and helps the one you love understand it too.. so you never have to explain yourself on your hardest days

eluna is a period and cycle tracker that helps you finally feel understood.

made by a couple, for the way love really works. she dreamed up every part of eluna, he built it, and together we made the tracker we wished existed.. one that helps you understand your body, and helps the people who love you understand it too.

most trackers just mark days on a calendar. eluna learns your rhythm and uses gentle AI to tell you what it means for your body, your mood, and your energy.. one phase at a time.
