Count from the first day of one period to the start of the next. (Around 28 days is typical — guess if you're not sure!)

What drove you crazy about other period apps?

Luna is your calm, private space. No accounts to create, no ads, and nobody spying on your body.

They store my intimate body logs on their servers Creepy targeted ads, data leaks & zero privacy

They charge $50 to $70 every single year Tired of expensive recurring monthly/yearly bills

Too much pink clutter, popups, and forum spam Just want a clean, calm, ad-free calendar

What is the toughest part of your month to handle?

Luna gives you a gentle heads-up before hard days hit so you can plan ahead.

The pre-period crash Sudden fatigue, mood swings & bad cramps before bleeding

Never knowing when it will start Unpredictable dates, spotting, or jumping cycles

Cycle Syncing & Energy Planning Align workouts, food & social plans with my 4 natural phases
