Willow®

More than an app. A support system.

Control your Willow pumps, personalize your pumping experience, and track your session history as well as your stash of Willow Milk Bags stored in your fridge and freezer. Plus, get access to expert guidance through articles, videos, live sessions, and new AI-powered chat, all designed to support you across pumping, feeding, and postpartum care.

Who can use the Willow app?
Our app is compatible with Willow Go, Willow Sync, Willow 360, and Willow 3.0. Plus, Willow Wave users can add their manual pump sessions to their session history. Our expert-led content and resources are available to everyone!

Operate your pumps with a tap.
Start and stop your session, switch between modes, adjust suction levels, and view your pumping duration, all from your phone. Save your Pumping Preferences, including suction levels and custom timer settings, and set reminders so every session works just the way you like.


Manage your session from your Apple Watch. Willow 360 and Willow 3.0 are the only pumps with full Apple Watch control.

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. With SmartStash, you can quickly and easily scan Willow Milk Bags into your digital stash to manage your inventory in the app.
