What it is
Kinoku tracks your cycle. You can also track having a baby. So you do not need a second app. Your training and your cycle live in one place. The tracking stays simple. It is not medical advice.
Private by design. Your cycle and baby data sits in its own file on your phone (
kinoku_cycle_db). That file is left out of Google’s cloud backup. A test locks this in so it cannot break by mistake. The data never goes to our servers. It is never sent to Health Connect.
What it covers
- Track your fertility. Tap a button to log how you feel. Track your morning body heat. It goes up a bit on the day after your egg drops. You can also log other body signs and tests.
- See what is next. Kinoku guesses your fertile day from up to five body signs. There is a mode for those who want a baby (called TTC). You turn it on if you want it.
- Track having a baby. A simple mode that tracks your due date. It also shows which of the 40 weeks you are in.
- Train with your cycle. Your Coach screen, your plan, and your stats know which phase you are in. Elite shows how your cycle and your lifts line up.
Health Connect
Do you log your cycle in another app? Kinoku can read it from Health Connect to help its tips. This is read-only. Kinoku never writes your cycle data back to Health Connect.
Why it matters
Does your cycle change how you train? Then it helps to see both side by side. Kinoku keeps that record private and on your phone. It shows you what your own data says. It does not tell you what to do.
