App takes giant step backwards

The recent update has made the Bluetooth connectivity, once reliable, useless. It does not connect, can not tell me the cooler performance parameters (temperature and setpoint) and likely won’t notify me of any alerts or malfunctions. Who knows - it doesn’t connect! I bought Truma over your competitor for the technology you brought to market. This update was a giant technological step backwards. I should be using an ice chest.

Hello BMInded,

Thank you for your message. If your cooler detects an error, this error will be displayed automatically on the control view within the app, from there you can navigate to possible solutions.
In addition we improved the bluetooth stability in the last update.

We hope this helped. Enjoy your Truma Cooler!

Previous version was WAY better

I do not understand why app developers feel the need to fix things that weren't broken. The previous app was way better and worked flawlessly. Example; the previous version showed the 2 zones with a picture. You always knew which zone was which because they are different shapes and volumes. Now the app just gives you zone 1 and zone 2 with no way of knowing which is which. You can't just go by left or right because this thing has the controls on the end and the lid is reverseable. Also, previously you could see and control both zones from the same screen. Now you have to toggle between at least 2 screens just to control and monitor the temperatures.

Can I please have the old version back?

Hello Property Inspector,

Thank you for your feedback. We are continuing to developing the app and its features. Feedback like yours is an important piece in the development process, as it helps us improve the app according to users’ needs. The zone identification feature you’ve requested is in development. Enjoy your Truma Cooler!

Great state of the art app

Just purchased the C30 and downloaded app. The qr code they included with packaging is a great idea. The app is fully functional and allows me to name my cooler and control it fully.

Glad I purchased this cooler and highly recommend it.
