No. OurCycle is not a method of contraception or a fertility tool, and does not replace medical advice. The mid-cycle band is an estimate from period dates.

Only what you switch on. Emotional weather, Phase & cycle day, Mid-cycle estimate, Specific symptoms, Intimacy signals and Share what OurCycle learns about me each have their own switch, with a live preview of what your partner sees. Your notes are never shared.

From your own logs, worked out on your phone. It starts adapting from your first cycle, and can spot your patterns from your third, if you log most days. You can pause predictions or reset your learning at any time.

Only if you turn it on. The daily outlook (Jev, an AI model made by TypeSafe) and the online coach (OpenAI) are optional, and each asks for your consent first. The daily outlook needs at least 10 logged days with energy and a natural cycle. On iPhones with Apple Intelligence, the coach can run on the phone itself. The learning that adapts to your cycle is OurCycle's own, worked out on your phone.

No. One of you can use iPhone and the other Android. Send an invite link by Messages, WhatsApp or Email: it works once, for 48 hours. On iPhone there's an Apple Watch app too.

Yes. OurCycle works for any couple. When you both have a cycle, each of you tracks your own and sees the other's, and each person's switches apply to their own cycle.

English, Spanish, Brazilian Portuguese, German and French, following your phone's language. The daily lines are written in each language, not machine-translated.

All 10 signals and, on iPhone, the next 7 days for your partner. Everything else on this page is free. One OurCycle Plus covers both of you.
