Private by design
Your cycle,
only yours.
No accounts. No ads. No analytics. Nari keeps your cycle on your device and in your private iCloud, learns your rhythm right on your iPhone, and shares nothing — unless you choose to share it with the one person who matters.
Built for two.
Shared on your terms.
Invite your partner with a single-use code, pick how involved they are, and see the exact list of what's shared before you connect. Try it:
You choose a goal
Your partner sees
Today's mood and energy shape the guidance. Notes and history are never shared.
Pairing codes work exactly once and expire after an hour. You can change the goal or unlink anytime — only today's values for your goal are shared, never notes or history, and they're encrypted on your device before they go anywhere.
No one in between
Your cycle lives on your device and in your own private iCloud. No analytics, no ads, and no servers of our own.

Nari observes basal temperature, moods, energy, and symptoms to reflect your patterns back to you — with humble estimates, like when your next period might arrive, never medical predictions.
Always yours
Export everything as a JSON backup, PDF, or CSV whenever you like — or delete it all from Settings. Nari keeps no copy of your cycle on servers of its own.
