Work With Your Hormones
for Better Productivity.
Period Productivity is a cycle tracker for people who want to know why some weeks feel effortless and others don't — and to plan around it.
Your cycle, in phases
Five phases worked out from your own cycle length, not a textbook 28 days. Each day shows where you are and what tends to come with it.
A minute a day
Mood, energy, digestion, sleep and productivity on a simple slider, plus whatever symptoms you want to note and a line about your day.
A calendar that fills itself in
Days you've recorded, and days ahead with their predicted energy — so you can see a heavy week coming before it arrives.
Summaries, when you ask
Pick any stretch of time and get a short read on what your own entries show. Observations about your data — never a diagnosis.
Privacy Mode
One switch keeps everything on your phone: nothing syncs to the backend, and nothing is sent to the AI provider.
Yours to delete
Edit or remove any entry whenever you like, or delete the account and take the whole history with it.
