Caldera Spa App
None of the features work. It’s been this way for two years now and the app is worthless. For as much as I’ve spent on my spa, you would think that they would spend the $50,000 it takes to make a premium app for all their spa owners that spend $15,000-$25,000 on a spa wanting to make sure it’s ready for me when I get home. This technology has been out for years and they are lagging massively. Not happy with this company.

Regret my Caldera Spa Purchase
The other reviews say it all. Worst app ever
Inconsistent since v2.3
Temperature adjustments haven’t worked consistently since the version 2.3 update. I hope they fix this since it’s been a good app to have.
Garbage app, garbage interface
Truly awful experience. The connected spa feature is garbage. Half the time the system is unresponsive. It takes 30 seconds for the settings to sometimes change on the hot tub, if you get lucky and it even responds at all. Even worse, I’ve had the connected spa system glitch out where it was randomly turning on the jets and lights until I restarted the tub and the WiFi adapter. Two thumbs down. Had I known how bad the app was I probably would have gone for another hot tub manufacturer altogether BECAUSE ITS A BIG DEAL.

Barely occasionally works
Recommend to stay far away from the Connected Spa system. When it works, the app, which looks like it’s from the birth of the WWW takes 10-15 seconds for any light or pump change to go through. It usually just takes your input and does nothing. Sometimes rebooting the spa fixes this but should we really constantly have to reboot a spa? Any suggestion that they might make the IQ chemical sensing data available in the app has been a lie up to this point - this would actually be a great use case. This is all the disappointing result of an obviously inadequate development team.

Poor app
Constantly loses connection to the spa. After adjusting the temp, monitor goes gray and freezes. Rarely works.
Unstable
Throws lots of errors adds others had mentioned
The Worst
Simply the worst app I’ve ever used. Apple doesn’t allow enough characters to share how bad it is.
DO NOT BUY
It’s been over a month that ABSOLUTELY NOTHING WORKS.
The temperature says 89 while my spa is at 99. Changing it does nothing.
DO NOT BUY THE REMOTE CONTROLLER, it’s absolutely terrible.

lawsuit time?
App has not worked in months. Time for a class action lawsuit as they sold us a load of garbage. Ridiculous that in 2025 they can’t make an app that works (even when they charge extra for it).
Work in progress…
The spa manufacturer is fantastic. Their products really are. Which is why their app is so bad. They are not an IT company and didn’t contract to one that builds apps well. It reflects poorly on an otherwise great product. For instance, the support link here takes you to their site’s landing page instead of an actual support link or email form. Hopefully, they correct things because the all is failing due to a “This data couldn't be read because it isn't in the correct format.” Error when you launch it. Wish I could tell them but the best I can do is post a review with the error and hope they see it.

Garbage
This app won’t allow me to even create an account using Apple ID, Google, or even email. Don’t use WiFi access as a selling point if your company is unable to properly maintain the service.
DAK Review
Very disappointed in the phone app. Paid the extra money but has never worked for very long. Requiring me to re enter all of the S/N and codes every couple months. Very frustrating and not reliable. It is convenient when it works but as stated you can't count on it.
Very bad
The server regularly goes out of service for multiple days, which is crazy. Last time it was for a week, this time it’s been 2 days.
Interface is very bad, just stop trying to do a nest interface for the temperature, just put up and down buttons for the temperature. The circular knob is very hard to use.
Please allow scheduling!! Or expose the shortcuts so that we can program it from iOS shortcuts app. This makes no sense to not have this.
Please allow turning economy mode on or off (I can only see if it’s on or not, but cannot change it).
Please make this a bit more professional.

Very buggy
Keep receiving an error message and will not let me log in.
Can’t adjust temperature after “bug fixes “
Can’t adjust temperatures after this update
No longer working
As of October 2024 the app no longer lets you raise or lower the temperature of the spa via the app. What’s the point of having this app and paying the extra $$ for the wifi module if you can’t even perform this basic task??
Needs to Match The Spa
In order for me to considerer this a good app it needs to have all the same functionality that the panel on the spa has. I can’t see what treatments the water needs without going out to the panel. Why would I want to turn the jets on from my app, but not be able to read the chlorine, PH levels, salt levels, etc. from the app?

Good App
App is easy to use. Love having the ability to set spa temperature remotely, no longer need to go outside and open up spa cover just to change the temperature.
Can only turn lights on or off with app, wish it could fully control the lighting the same as spa control panel. Hopefully this will be added in a future app update.
