The HUUM App 4.0

Our partner at HUUM Sauna just shared some exciting news about their latest app 4.0 which has been officially launched in June 2026. Built to be faster and simpler to offer the best sauna experience, App 4.0 is a complete rework of how you control your sauna.

Here’s an overview of the new and exciting features advertised by our partner:

🌡️ All your saunas in one view See current and target temperature, status, and any alerts for every sauna at a glance. Online, offline, or heating — you always know where things stand.

🔔 Smarter, real-time alerts Clear, instant feedback when it matters — an open door, a lost Wi-Fi connection, or a remote-start safety check. You're never left guessing.

📅 Booking made easier Set the day, time, temperature, and duration in seconds — and save recurring sessions so your sauna is ready before you walk through the door. Your next booking stays visible up front.

⚡ 3× faster control The app and your controller now talk to each other three times faster. Every command responds instantly, with no delay between tap and heat.

📊 Know your sauna habits Track your total sauna hours, browse your full session history, and see each heating session charted out. A clearer picture of your time in the heat.

The biggest upgrade to be touted here is “You won't see it. You'll feel it in every single tap.” The HUUM team has rebuilt their entire server infrastructure from the ground up. Every part of the engine that connects your phone to your sauna. So, if you’re a HUUM customer with an UKU WiFi-enabled heater, try updating the app on your phone to get the latest features and let us know what you think!

Regardless of whether you are new to sauna or ready to upgrade your existing heater system, we have you covered. Take a look at a wide array of HUUM heaters available here in North America!
