Love my water bottle

Amazing

The Bottle Not Widget

The bottle works great. I average two days on the life of the battery top. The widget is incorrect. It needs an update

Does Not Sync w/Apple Health

This app lacks the ability to share and sync hydration with health apps like Apple Health. I get the privacy concerns, but the user should be able to choose what data gets shared. This is a major drawback and significantly limits the usability of this device as a β€œsmart” bottle. Please prioritize fixing this.

Makes Drinking Water Fun

I’m notorious for not drinking water in my house. I literally have to flavor it for it to be tolerable. But that has changed with this Water.io bottle and app.

I’ve realized that when things are gamified on an app, I will do it because it holds you accountable. There is something that clicks in your brain when an app notifies you that you have reached a given goal.

I’m so happy I’ve found this great bottle and accompanying app. It’s going to change my health dramatically. Thanks for making drinking water fun. I’m starting to be able to drink it without having to flavor it. lol

Missing Apple Watch integration

Missing Apple Watch integration means you can’t add this as a complication. Which means you can’t simply look at your watch to see how much you’ve had to drink. I hope this is added soon as we’re stuck with using this app with their water bottle .
