Ratings and reviews

if you buy the flask for $300+, I would DEFINITELY expect the app to be working flawlessly. that's not the case at all. the app as of late, crashes every single time after the app opens, connects to device, and then when syncing the cycle, the app crashes. EVERY TIME!! I can't get counted for my efforts! now, for the 2nd time in a year, I can't get my daily count! I drink this every day for around 350+ straight days!!! and now for 2 days, gonna go on 3, the app is awful!!!!!! the worst for $300!

This app is frustrating. It doesn’t track progress correctly and constantly logs me out. A water bottle app isn’t something you check daily—more like weekly, similar to a fitness app—so when you do check, you expect accurate data. If it can’t reliably track my intake, what’s the point? My phone is with me 24/7, so if the bottle is nearby, tracking shouldn’t be an issue.

So far the app and the flask don't match in consumption stats. Connectivity between the app and the flask are intermittent at best. The app doesn't provide a way to update flask usage if they don't update themselves. I've also tried updating the firmware via the app and there is an error of some sort that doesn't allow the firmware to be updated. At this point the app is wasting space on my phone. Update: 8 flasks in and the app has only recorded 2. The flask is tracking well.
