Ratings and reviews

This app is almost worthless. One pump will almost never connect, the other takes several minutes to connect and disconnects frequently, especially if I look at anything else on my phone. Since it's usually not connected or trying to connect, I can't really use it to operate the pumps. It doesn't even keep accurate time, despite an update the other day that supposedly fixed that problem but has not.

This app does not sync accurately with the Willow 3.0 pumps. The pumping session start times are inaccurate if I am offline during the session and sync the information to the app afterward. Some of my sessions are not recorded in the app if I am unable to get online until after midnight. I do appreciate the ability to select if I want to measure the amount pumped in mL or oz. I also appreciate the ability to edit the amounts if they are slightly inaccurate.

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.
