280days is a free pregnancy record and diary app that connects not only the mother and father, but also the baby in the mother's tummy. The app is packed with services and functions that make pregnancy more enjoyable, such as baby illustrations that grow based on the number of weeks of pregnancy, week-by-week pregnancy advice, and message cards. The app allows mothers to manage their physical condition and medical checkups, record ultrasound photos and weight records, and save maternity photos and memories of pregnancy as a photo diary with their spouse.

The app also provides week-by-week advice in 280days, which comes with illustrations. The advice covers how the baby is growing, how the mother's physical condition changes, and advice on how she could spend her time at each week of her pregnancy. The app enables fathers to understand pregnancy better and help improve communication between couples. The app is fully equipped with functions to support mothers throughout their pregnancy, such as pregnancy countdown and weight management graphs.

Users can export all their pregnancy records saved in 280days to an easy-to-read layout exclusively for books. The app also offers a function to hide the advertisements displayed at the bottom of the app through in-app purchases. The development team of 280days hopes that the app will connect the family during pregnancy and nurture new ties. Users can email totsukitoka.support@amanefactory.com for any enquiries, requests, or issues regarding the app.
