PERIOD. plus

Know your own cycle, not a generic one.

The free app tells you when your period comes. Plus tells you why this month feels different from the last, and gives you something to bring to your doctor.

3.99 per month or 34.99 per year

First 14 days free. No payment now. Cancel with one tap in your app store.

Your own assistant

Ask any question about your cycle, day or night. The assistant knows your logs and remembers the context of the past thirty days, so you never have to start over. Up to a hundred messages a day.

A doctor report your doctor reads at a glance

Unlimited PDF reports with your cycle, bleeding, pain and symptoms per day. Take it to your GP or gynaecologist. It is the difference between "I often have pain" and a three month overview.

Insights across multiple cycles

A cycle report, a heatmap of your complaints, a map of anomalies, temperature trends and a yearly overview. Plus learns what makes your cycle different from the average and says honestly how certain it is.

Fertility, complete

Log your basal temperature with a chart and coverline, your ovulation tests and your cervical mucus. Together they show when your fertile days really fall, even when that is not day 14.

Everything your way

A journal that merges symptoms, notes and mood per day. Custom symptoms with an icon of your choice, including skin and digestion. Log your weight. Drag, reorder or hide blocks on your overview. Set reminders in detail.

Share and connect

Let your partner follow along safely. Put your cycle in your Apple, Google or Outlook calendar. Lock the app with a code.

Who plus is not for

  • You only want to know when your next period comes. That is free, and it stays that way.
  • You are pregnant or trying, and want guidance through recovery. Look at PERIOD. baby instead, that is a separate step.
  • You expect a medical judgement. PERIOD. is not a medical device and does not replace your doctor.
