## What is HUUM?

Your sauna, ready when you are.

The HUUM app puts full control of your sauna in your pocket. Heat it up on your way home, fine-tune the temperature from the bench, and keep an eye on every session wherever you are.

WHAT YOU CAN DO
• Start, stop, and adjust your sauna remotely
• Set the exact target temperature and session duration
• Schedule sessions by day, time, and temperature, including recurring bookings
• Watch live status, current and target temperature, and heating progress
• Manage multiple saunas from a single view
• Track your sauna hours and browse your full session history
• Get clear, real-time alerts for doors, connection, and safety

BUILT FOR SAFETY Remote start is enabled only when your sauna's safety is confirmed through the UKU control panel, so you stay in control at all times.

Works with HUUM saunas equipped with the UKU controller and a Wi-Fi connection.

Less fiddling. More leil.

### 1/5 — Juvenile software

*2026-05-16*

I don’t understand how an actual company can release this total garbage and call it software.  Impossible to configure.  Regularly forgets settings.  Strongly suggest you spend another $500 on your development team and get someone over the age of 11 to develop it.  You should be ashamed of yourself and the garbage you are putting out and calling software.

### 1/5 — Horrible App

*2026-03-29, version 3.1.0*

This is one of the worst apps. It’s full of bugs and basically useless. You would think that HUUM would be able to spend a little bit of time figuring out to make use of this with a thousand $ sauna.

### 1/5 — This app needs a lot of work

*2026-03-17, version 3.1.0*

The temperature will not adjust from the app. Sometimes the app won’t even turn the heater on. For such an expensive heater they need have an app that works.

### 1/5 — Scheduler broken

*2026-03-15, version 3.1.0*

Scheduler broken

### 1/5 — Language

*2026-03-11, version 3.1.0*

Every time I set it up it will not stay in the English language. I reached out to their support and they never responded.

### 1/5 — No longer works on iPhone with latest IOS

*2026-03-07, version 3.1.0*

App is basic but functional - delays on light just take getting used to but I can no longer use the remote function as the latest iOS doesn’t seem to work with it

### 1/5 — Not reliable

*2026-03-07, version 3.1.0*

The app doesn’t work reliably. The latest update won’t even open.

### 1/5 — What’s the point!?

*2026-03-05*

I used to be able to set my heater to start automatically. As of Feb 2026 that feature no longer works, but the button to start automatically is still there. Why even out it there if it’s disabled? No one has responded to my emails to advise. I’m waking up at 4 am every day to turn on a heater that I specifically purchased bc of the app remote auto start. Bring it back!

### 4/5 — HUUM App Works

*2026-03-03, version 3.1.0*

This is an app that works. You can turn on Sauna and light and manage temperature from anywhere. Its got a slight delay of about 4-5 seconds when you operate LED lights but no big issue - really don't get the Low rating must be tactical from a competitor

### 1/5 — Huum

*2026-03-03, version 3.1.0*

Very disappointing the app no longer controls the sauna to allow you to set upcoming events. Would be nice to see this issue get resolved.
