## Description

GLAS by JCI brings Johnson Controls' heritage of reliable climate control to a modern Chrome extension experience. The GLAS app lets you remotely manage your thermostat, view indoor and outdoor air quality, and adjust temperatures and modes from anywhere to keep your spaces comfortable.

From guided installation to multi-location control, GLAS supports scheduling, voice commands, energy usage tracking for the last seven days, and proactive notifications for poor air quality and HVAC reminders. Manage more than one GLAS thermostat across locations, auto-adapt to daily routines, and optimize energy savings without sacrificing comfort.

## Review summary

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.
