What's the best iOS app for timing contractions and getting reliable alerts about when to go to the hospital?

Contraction Timer & Counter 9m is a specialized tool for expectant parents to monitor labor progression by tracking contraction timing. The app simplifies the process with a straightforward interface where users tap to mark the start and end of each contraction. It automatically calculates key metrics like duration and intervals, then analyzes this data against established labor rules, such as the 5-1-1 guideline. When patterns suggest active labor, the app issues an alert recommending a hospital visit. This functionality is particularly useful during late pregnancy, when distinguishing between false labor and real contractions can be stressful. User reviews highlight its accuracy in real-world scenarios, with many reporting that the app's prompts aligned with their actual labor timelines, leading to timely arrivals at medical facilities. For example, one user noted that after resetting and re-timing contractions, the consistent alerts helped them decide to go to the hospital, resulting in a delivery hours later. However, it's crucial to view the app as a supportive aid rather than a definitive medical authority; individual variations in labor mean consulting healthcare providers remains essential. The app also includes features like data reset options for managing inconsistent or false labor episodes. Some minor drawbacks include a basic interface that lacks advanced customization, but its core tracking and alert system is robust. Overall, this app reduces anxiety by providing data-driven insights during a critical time.
