What’s New

Version 1.11.9

This update provides a bug fix related to app widget.

With the 1.11.6 version the app has some great overall visual and interface improvements, added support to make full use of the iPhone X screen size, and the H2OPal Apple Watch app now has better graphics. We've also fixed some bugs that were still left over from the latest major Apple Watch software update.

Here's what's new in greater detail:
• Fixed issue on Apple Watch where intake recorded on the Apple Watch didn't transfer to the main app. (Please note that it can take some time for the intake logs between your Apple Watch and the iPhone to sync. Opening up the H2OPal app on your iPhone after making a measurement on your Apple Watch can make sure the measurement gets synced faster.)
• New radial progress bar graphics on the H2OPal Apple Watch App. It's the same type of progress bar you're familiar from the H2OPal home screen and the H2OPal widget so that we can provide a more consistent experience throughout all the apps.
• Small improvements in the layout of the Home/Profile screens for a more consistent design throughout the app and support for the iPhone X screen.
• The design of the individual contributions towards your total intake on the Logs screen has been significantly improved.
• Improved design of the weekly graph on the Profile screen.
• New design for the initial Tracker Pairing process. (More sections of the app will be updated to this new aesthetic with future updates.)

As always we’re happy to hear from our users and if you find or need help with any bugs or issues please feel free to reach us at

Great app, but...

Love the app. It really inspires me to drink more water by tracking the amount I drink and setting goals. Here’s the but - The only problem is the inability to adjust active hours. This app is perfect for regular 9-5 people. For those of us that work night shift, the app’s benefits are almost useless, unless I want to drink my day’s requirements as soon as I wake up in the PM and before 10PM. The developer said they can’t fix this because it wouldn’t work with associated health apps. How about giving an option to not connect to health apps to open the opportunity to adjust active hours? Beyond this, I love it. Re-syncing the bottle is simply turning it upside down. A couple things I have learned, If you have been drinking while not synced, the log will catch up when you do sync back up with the app. Lastly, you do have to remember to set the bottle down for a second or two before refilling to account for your last drink. But, if you mess up, make a manual entry. After approximately 20 days of daily usage, my battery is at 89%. I would recommend this to most people. Maybe not night-shifters.

App 4/5, bottle 5/5, some issues

I’ve had 0 issues with it. Curstomer Support is great. Tracks my water intake perfectly. Pretty customizable. I think it’s a 5/5 bottle, 4/5 app.
Missing features:
1. Ability to post date water intake. Sometimes I forget to manual add water to the day before it “locks out” that day.
2. Latest that your day can “end” to reset is 2300hrs. That’s silly. Some people’s days/nights end later than that. Also, not myself, but some people work midnights and don’t have normal days. Why limit the app in this way?

Dead Simple and Very Helpful

Having recently gotten an Apple Watch and finding its tracking surprisingly motivating, I decided to try a water tracker app. There are some good apps for doing that, BUT you have to log (and remember to log) every intake.

Paired with the H2OPal bottle, this app does it automatically and accurately. And the manual logging of my coffee is dead simple on both the iPhone and the Watch. I’m enjoying using it, and it is helping me change my water intake habits.
