A clear last hour
The count, the average length, the typical interval and whether they are regular, at a glance, with no table of numbers.
Tap Start when a contraction begins and Stop when it ends: the app works out the length, the interval and the pattern of the last hour.
It tells you when that pattern matches the common guideline for calling your midwife or hospital, from an official source. Your own hospital's advice always comes first.



One big button, easy to tap in the middle of the night, even mid-contraction.
How many contractions, their average length, the typical interval, and whether they are regular.
When your pattern matches the common guideline for your language, the app says so and names its source. If in doubt, call.
