Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Slow, laggy, battery10%

2 of the 1 and 2 star reviews.

★★★★★ using too much battery even if its idle.
★★★★★ Disproportionate battery consumption(even in optimized mode) for an app with basic usages: adding records and counting elapsed time.
WHAT THEY ASK FOR
  • Subscription is too $$$ But unlike Nara, let's you do basic tracking for free...just wish they let you do one additional caregiver free then charge for additional ones after that. 3★, Oct 17, 2026
  • There's one thing I would really like to see, an option to add a reminder as an alarm, not only as a notification. 5★, May 7, 2026
  • I wish I had found it sooner, with brain fog postpartum it definitely takes the stress out of trying to remember when baby ate last or how many diapers she's had for the day. 5★, Jul 21, 2025
  • EDIT: Would be great to have the ability to duplicate a record across two people. 5★, Jul 15, 2025
  • The only problem that i have is when i want to add a widget to my home screen l, it will not appear. 5★, Apr 18, 2025
  • great app, wish there were options for homescreen widgets 4★, Mar 31, 2025
  • Needs to have a better interface for twin babies. 4★, Mar 22, 2025
  • Needs a better interface for mother's profile. 4★, Mar 22, 2025
