This app is nothing fancy but it syncs with my pumps easily. I like that I can see battery power within the app as there isn’t a display on the willow pump. So far no issues with it as others have complained about. It’s absolutely not necessary to have to use the Willow but it is nice to see time elapsed and battery life.

I love my Willow Go due to the lack of tubing and wearability of the pumps, but the app needs a lot of work.
1. The battery icon is so small, it’s hard to tell if the battery has fully charged and how much is left—it should have a % option rather than a dinky little icon. Or the icon could also be green or yellow based on how much charge is left. I know the light on the pump shows this, but it would be easier to see it all in one place. It does show red in the app when you’re critically low, but then it’s nearly too late.
2. There should also be an option to press one button to double pump at the same time and same suction. While it’s nice to be able to have two different suctions per side if that’s what you need, if you just want the same suction you have to strategically press start and increase or decrease suction at the same time. If you don’t do them at the same time, the pumps are out of sync and completely annoying, sounding like they are echoing each other. I can’t get them in sync through pressing the buttons on the pump itself, so the app is essential to get them going at the same time.
3. It would be nice if the connectivity didn’t take so long. I get it, you need to be in range or the machine. But if they’re sitting right next to each other with the phone barely 4” away, they shouldn’t take so long to connect.
All in all, I like the app so they I can get the pumps sounding like one pump, but needs work.

I have to restart my phone a few times a day to be able to connect the pump. It’s been getting progressively worse the last couple of weeks and honestly I wish the app offered more.
I’d love to see daily averages, more accurate time logging, and possibly a community forum. I also don’t like how you have to know which pump it considered left and right, I had to label mine which was a bummer.
