Three things no other app gives you
A perspective built for you
Every competitor app was designed for the person tracking their cycle. The partner is an afterthought — a notification recipient, a calendar viewer. Yuni flips it: you are the primary user.
Daily "what to do today"
Knowing she's in her luteal phase doesn't tell you what to do. Yuni translates each phase into specific, actionable guidance — what to say, what to avoid, what she needs right now.
Zero exposure, zero accounts
Her reproductive health data never leaves your phone. No account, no cloud sync, nothing to breach. Every other app on this list requires signing up and storing data on their servers.
A completely different category
Period trackers are great at what they do. Flo, Clue, and Stardust are genuinely impressive products — for the person tracking their own cycle. Even Flo's partner feature, the most ambitious attempt at this, still treats the partner as a secondary user of a woman's app.
Yuni doesn't compete with any of them. It fills the gap they all left open: the partner who wants to show up better, understand what she's going through, and know exactly how to help — without needing her to be on any app, without needing her to explain it every month.
No account. No cloud. No logging. Just enter her cycle dates once and Yuni handles the rest.
