Ratings and reviews

use to be a 5 star review, now for some reason I keep having multiple issues, connection is the biggest one keeps telling me I have to take it apart and put it back together ( did it 10 times) and still don't want to work. then one of them won't pair to the app. I tried deleted app and then reinstalled, still can't get it to pair, says the left side is paired but the number is for the right side. So honestly it's so screwed up

Right now, the app is really only useful for starting, stopping, and adjusting the pumps. It is supposed to also allow for tracking but I'd say 3 out of 4 times my pumps get dropped so I cannot see all my pumps nor add volumes. A feature I'd also like to see is more comprehensive tracking logs and trends. Occasionally, I'd like to see more than one day's data at a time, and see overall/lifetime pump totals.

It's nice to have an app working in tandem with the pumps; however, more often than not, the app is messed up... for example, most days after a session the session is not recorded so I have to make note of the milk volume in my notes app and sometimes it will take a day or two for all the sessions to actually record. right now, the last session recorded was from yesterday at 630 a.m., and I've had 5 sessions since then all waiting in my notes app for the Willow app to get it together. need 2 fix
