The equipment/hardware is fantastic when it works as marketed. I owned the Chilipad and then upgraded to Ooler when released. I’ve had consisten app connection problems and sleep schedule issues. Presently, my system no longer recognizes the sleep schedule and I can only manually turn on and off. My husbands system no longer connects via app. Issues happen with a fair amount of regularity - - which is far too often for a system that should otherwise run automatically except for the occasional maintenance. Speaking of which, I never get notice of low water level. This is something I have to check manually. Being in the health field, this is a product I want to highly recommend...but can’t for the above reasons. I do truly hope these issues get resolved. It’s an expensive piece of technology.

App needs a lot of work

The ooler is a decent system that is only marred by a poor quality app. The UI bugs are getting better but the sleep schedule is still very hit or miss since the last update. I now have to go manually turn on or off the device a few nights a week despite having a schedule set for every day.

Requiring a login to even use the app was a business decision that needs to be rethought. The app and device should continue to function even if Kryo Inc moves on and shuts down the servers that support the app someday but it is currently designed to not do that.

Worst App I have

1. My sleep schedules get randomly deleted.
2. Often when I try to adjust the temperature on a sleep schedule, I get a message saying the time isn’t in the sleep range when it clearly is. (3am adjustment in a 10pm-8am schedule.)
3. When traveling with my ooler, good luck getting the Bluetooth to connect and actually run the schedule.
The pad itself seems to be fine although I would prefer more tubes closer together but the app is clearly not up to the standards one should expect with an $800 purchase.
UPDATE: August 2020
I am downgrading my stars to 1. I have even more issues with the app after 7 months than in the beginning. Now, my sleep schedules get deleted and then, magically, all of them or 1 of them - reappear on some random day. I have the bed time alerts turned off but I still get them. My Ooler has been shutting off in the middle of a sleep schedule and then kicking back on after a few minutes. 🤷🏻‍♀️ None of my issues have been resolved. I get emails from the developers asking for more info and when I give it, I get cut-and-pasted answers that don’t even apply to my issues. This buggy app is still not functioning correctly and I see no moves to fix it by the developers. Therefore, it gets 1 star. But that’s only because I can’t give it 0 stars.
