Contraction timer
One large button for timing. Clear duration, frequency and recent averages for the conversation with your maternity team.
Direct answer: time each contraction from start to finish. Frequency is measured start to start. True labor often becomes more regular, closer together and stronger—but an app cannot confirm labor.

Read duration and frequency correctly
How long one contraction lasts, from the moment it starts until it releases.
The time from the start of one contraction to the start of the next contraction.
Patterns are useful; your care plan decides the next step
ACOG's labor guidance says true labor contractions usually follow a regular pattern, get closer together, last about 60–90 seconds and steadily strengthen. False labor may be less regular and may stop with rest, walking or a change of position.
There is no app rule that applies to every pregnancy. Before your due date, agree with your obstetrician, midwife or maternity unit when to call, where to go and whether your own circumstances change that plan.
Contraction timer questions
How do I time a contraction?
Start when the contraction begins and stop when it ends. Duration runs from beginning to end; frequency runs from the start of one contraction to the start of the next.
Do regular contractions always mean labor?
Labor contractions generally form a regular pattern, get closer together and become stronger, but only a clinical assessment can confirm labor.
When should I call my maternity care provider?
Follow the personal instructions your care team gave you. Call if you think you may be in labor or are unsure; seek urgent advice for heavy bleeding, constant severe pain, reduced fetal movement or if your water breaks.
