HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (51 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.4 times, so the range is wide. 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.

Scan and manage Willow SmartStash Bags in your fridge and freezer. Plus, get access to expert guidance from educational content, live services, and our specialized, AI-powered chat—a virtual support system designed to support you across pumping, feeding, and postpartum care. Who can use the Willow app? This app is compatible with all connected pumps, including Willow Go, Sync, 360, and 3.0. Willow Wave users can manually add manual pump sessions to their session history.

All of the pumping, feeding, maternal healthcare, parenting and baby development resources in the app are free for anyone to use! Operate your pumps with a tap. Start and stop your session, switch between modes (Go and Sync), adjust suction levels, and view your pumping duration, all from your phone or smart watch. Set up your own Pumping Preferences, including suction levels and custom timer settings, and set reminders so every session works just the way you like. Get the only app that lets you control your session from your Apple Watch. NEW! You can now control your Go pumps, in addition to Willow 360 and 3.0. Track your sessions. Understand your output. Follow your milk output, session durations, add manual pump sessions and more for a complete picture of your pumping history. Spot trends, optimize your routine, and pump with confidence.
