This is the simplest contraction tracker that will help you track your contractions and tell you when it's time to go to the hospital! Just measure a few contractions by pressing the button at the beginning and end of each one. The app will analyze their duration and frequency to determine when it's time to go to the hospital. Always consult your doctor to understand what duration and frequency of contractions to focus on. This app is not a medical tool, and our recommendations are based on generally accepted values. Your labor may be unique, so do not rely solely on this app. Even if the duration and frequency of contractions do not correspond to the required values, but you are experiencing severe pain, it is better to go to the hospital early than to risk giving birth on the road or at home. Trust your feelings. Unlimited access subscription: - You can subscribe to unlimited access to all the features and content offered for purchase in Contraction Timer. - Price: Get full access to all Contraction Timer features with an in-app purchase of $1.99 per week.

ReceptionRating · Positive reviews · Number of ratings

Baby Diary holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Baby Diary has 146 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 62% of Baby Diary's written reviews are positive against 100% of Contraction Timer & Tracker Mo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Baby Diary ships an update every 3 days, Contraction Timer & Tracker Mo every 2 weeks. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
