I had high hopes for this bottle and app. the bottle is fine, but it doesn't stay connected to the app. the tracking is spotty. In a nutshell, the bottle and app aren't often synced, which means it doesn't always track the water, which kind of makes the whole experience useless. I bought the bottle so it'll automatically track my water intake for me and it just flat out doesn't do a good job at it. I will 100% update my review if this improves btw. Awesome idea, it just doesn't quite work yet.

Update: if you e getting this bottle for the tracking, don't. It doesn't track and it's always offline BS. You'd think they have better developers for a $130 cup brand. This app opens when it wants to, sometimes takes several attempts to actually get the app to work. The tracking doesn't track consistently. Overall sucks.

A year has passed, a few updates have been made, nothing has improved; tracking has worsened, and no new features have been added. I have now cancelled my Nano filter subscription after one year of owning the PurViz 2, and it is going into the recycling bin. You are clearly focused on iPhone/Apple, and that is not a sensible business strategy "Eggs all in one basket" is the term I would use. If you actually responded to people's reviews and provided an update, that would be polite and helpful.
