Our application is a helpful app designed to track contractions during pregnancy, allowing expectant mothers to monitor the duration, intervals, and frequency of their contractions. It features a contraction timer and counter, providing detailed history in a list format for easy review. The app includes checklists for different stages of pregnancy with useful recommendations and tasks before, during, and after labor. Users can follow a step-by-step guide to understand how to use the app effectively. After each contraction, you can rate its intensity as weak, medium, or strong, helping you keep track of how labor progresses. The app also offers statistics for the last hour, showing average contraction length, count, and frequency. You can edit contraction records by adjusting start and end times or adding and deleting entries manually. Informative articles on childbirth preparation, recovery, and self-care are also available. The free version allows contraction tracking and access to the user guide but limits intensity rating, history editing, and article content. Upgrading to the Premium version unlocks daily pregnancy tips, full access to intensity ratings, and the ability to edit contraction history. Our application is an essential companion for mothers preparing for childbirth, providing practical tools and support throughout labor.
