### 1/5 — Unreliable

*2026-02-08, version 2.4*

Constantly needs resetting despite SNA being hardwired to network and placed close to spa. Even after resetting may not always work. Extremely buggy.

### 1/5 — Completely broken

*2026-01-18, version 2.4*

This app is worthless. You’ll be mad you ever tried.

### 1/5 — Not worth the cost

*2026-01-18*

I purchased this option thinking it would be useful to monitor my hottub.   The radio setup required me to have a Ethernet port to plug in the Digi adapter.   The app doesn’t show proper information, and when changing my salt output it never matches the panel display.   I don’t have confidence it reads the temp right and impossible to tell if it’s connected or providing “dummy” data.   The round gauge doesn’t match the gauge on panel either after performing a salt test.

### 2/5 — Basic

*2026-01-05, version 2.4*

Would be great if you could choose light colors. My control panel went on my hot tub so I had to get the wireless app. Very basic.

### 1/5 — Simply stopped working

*2025-12-12, version 2.3*

Can’t control my spa anymore.  For an expensive add on, with no API access, this is very disappointing.

### 1/5 — Never sent confirmation email

*2025-10-13, version 2.2*

🤮

### 1/5 — Garbage

*2025-10-10, version 2.2*

Doesn’t work. Always disconnects. Temp isn’t what is set. Salt level is wrong. There is so much wrong with this app and so little of anything good. Why? Why such garbage yet such great spas? Embarrassing.

### 1/5 — Junk

*2025-09-18*

This worked for about the first week. I’ve had my hot tub three months now and this app is completely worthless. I live in a northern climate where it can go to -30°F and thought this app like protecting me if the hot tub heater failed.  Well now it is almost October and I need to figure out another option to monitor my hot tub temperature. 

Yeah, does little to nothing for Bluetooth connectivity for your music. I used to be able to turn up the chlorine system, but that doesn’t work. I used to be able to turn on the lights, but that doesn’t work. Pretty much nothing works.

### 1/5 — Super minimal for the price

*2025-08-16*

Not worth the money. It’s super glitchy. No audio control other than input type. No reporting of the water quality monitor. Salt system reporting only.   Can’t control the lights or adjust light color. I paid a thousand bucks to have this added and am super disappointed. I wish the dealer would have shared the limitations before i shelled out a kilo buck.

### 1/5 — App doesn’t work

*2025-08-15, version 2.2*

This App has only worked for about a day after resetting everything including the router and its module. This has been going on for two years. Love the hot tub but can’t control it remotely. Terrible!
