Contraction Timer & Tracker IO

Contraction Timer IO is an ad-free contraction timer app and contraction tracker for Android, used by more than 500,000 parents. Tap once when a contraction starts and once when it ends: the app measures contraction duration, frequency, interval and intensity, and alerts you when your pattern matches the 5-1-1 rule, so you know when to call your provider or go to the hospital.

HOW TO TIME CONTRACTIONS

• Tap the big button when a contraction starts, tap again when it eases

• See duration, frequency and contractions in the last hour on one screen

• Rate each contraction as mild, moderate or strong

• Missed one? Add it by hand, edit or delete any contraction, free

• Breathing guide inside the timer, with calmer colors as labor progresses

• Start and stop from the home screen widget or the live notification

WHAT DOES A CONTRACTION TRACKER MEASURE?

• Duration: how long one contraction lasts

• Frequency: time from the start of one contraction to the start of the next

• Interval: the rest time between contractions

• Intensity: how strong it felt, in your own words

Your contraction tracker history shows how labor contractions change, with charts of how long they last and how far apart they are.

WHAT IS THE 5-1-1 RULE?

Contractions about 5 minutes apart, lasting about 1 minute, for about 1 hour. This contraction timer alerts you with "Get ready" and "Go to the hospital" when your timings match. Some providers use 4-1-1 or 3-1-1, so you can set your provider's own rule. Smart stats restart after a long break, so early or false labor doesn't skew your numbers. A timing pattern alone can't confirm labor.
