User Reviews

Users generally praise the GLAS thermostat hardware, noting it looks good and the device itself works well when accessible. The major pain point is the companion iOS app: frequent login failures, account/password frustrations, and very slow performance. A recurring theme is the lack of ongoing support, updates, and the discontinuation of cloud services, rendering the app unreliable or obsolete. Password autofill issues and missing biometric sign-in features also appear. Overall, the hardware is solid, but the app makes it difficult to use the product effectively.

Pros

Hardware design and build quality is praised; the GLAS thermostat looks great.
The thermostat hardware itself is reported to work well when it functions.

Cons

Widespread login problems: cannot sign in, sign-in timeouts, and frequent failures.
Account creation and password issues: can't create an account, password resets fail, and passwords often aren't saved.
App performance is very slow and often fails to load or initialize for many users.
Lack of ongoing support: updates stopped years ago and cloud services are discontinued, making the app unreliable or obsolete.
No biometric sign-in (e.g., Face ID) and other convenient sign-in features are missing, with users calling for modernization.

The title says it all. Can’t even use the app

All of a sudden I can not login to the app. Says it can’t send me a lost password email because my email isn’t recognized. So frustrating!!!! Less than 1 star!!!!

Hardware looks great. But it’s not smart. And can no longer even control it from my phone. At all. It won’t even log in. And when it did, you had to enter your email and password every single time. Terrible.
