Notice your pattern
Keep period dates, check-ins, symptoms and notes in one calm, uncluttered place.
A gentler cycle companion
Nerina is a calm, private space for tracking your cycle, noticing patterns and finding clear, non-judgmental support — at your pace.
Private by default. No ads. No product analytics.
Made for real life
There is no “perfect” cycle to chase. Nerina helps you hold onto what matters, then gently lets the rest go.
Keep period dates, check-ins, symptoms and notes in one calm, uncluttered place.
Choose the level of detail that feels useful. Your records remain on your device by default.
Optional educational tools and an adult community are designed around safety, boundaries and kindness.
Small choices, real privacy
Nerina begins on your device. We do not use advertising SDKs or product analytics, and connected features are always a choice.
Always clear, never hidden
Read the policies in plain language, contact support or manage an optional account without needing the app.
