Check in
Log flow, mood, pain, symptoms and the personal signals that matter to you.
Private period tracker for iPhone
Log your period, mood, flow, pain and symptoms. Moonwave shapes your daily check-ins into a moon mandala-without an account, company journal servers or a subscription.

A gentler daily ritual
Log flow, mood, pain, symptoms and the personal signals that matter to you.
Each check-in adds another mark to your evolving 28-day moon mandala.
Look back across cycles and reflect on the rhythms that keep returning.
Menstrual cycle journal
A cycle is more than a start date. Log energy, mood, comfort, focus, appetite, libido, cramps, bloating, movement, sleep and custom signals in a few taps.

Personal pattern views
Moonwave reflects recurring signals from your own journal. It is a quiet place to notice and revisit-not a medical prediction, fertility tool or substitute for professional care.

Private by design
Cycle information can be deeply personal. Moonwave avoids its own account system and company journal database, stores entries locally and uses your private iCloud database when sync is available.
Simple pricing
Create your first mandala free. If Moonwave feels right, one lifetime unlock opens full history, patterns, themes, sharing and exports. It does not renew.

Questions, softly answered
Moonwave supports personal wellness reflection. It does not provide medical advice, diagnosis, treatment, contraception or fertility guidance.
