For her, to send to him
Stop explaining it every month.
TideBook tells him where you are in your cycle and what actually helps that day: the tea, the patience, the space. Send it once. He takes it from there.

What he sees each day
He'll know what today needs.
Every day he sees which part of your cycle you're in, what usually comes with it, and a few concrete things that help right now. No guessing, and no lecture from you.
- Where you areThe current phase and day, in plain language.
- A short daily playbookPractical things he can do: take a chore off your plate, keep plans light, have your snacks within reach.
- The next two weeksA 14-day outlook, so the week before your period doesn't catch him off guard.
Gets better as he logs
Your pattern. Not the textbook average.
Most cycle apps for men use the same formula. TideBook starts there, then learns from what actually happens between you two.
One tap a day from him is enough. The more he logs, the more the forecast moves from the textbook curve toward yours.
The whole setup
He adds one date. That's it.
He enters the day your last period started. After that, TideBook asks him for one tap a day.
Private by design
Nothing leaves his phone.
No account. No cloud. No tracking inside the app. What he enters stays on his device, and he can erase it at any time.
Ready when you are
Send it to him.
One link with a short note, straight to your chat with him. Or read first what to tell him, part by part.
