Review summary

Users largely rate the Ember Android app as unreliable: it often disconnects, struggles to pair, and requires re-login or repeated re-pairing. Updates frequently worsen these issues, occasionally causing crashes. While the mug hardware is liked, the app experience is the primary blocker. When a stable connection is achieved, control over temperature works as intended. Overall sentiment is frustrated, with sign-in friction and persistent connectivity problems dominating feedback.

Pros

When the app connects to the mug, it controls temperature and settings as intended.
Some users report workable behavior when a stable connection is achieved.
The Ember mug hardware is well-liked, providing a good base experience if the app works.

Cons

Frequent disconnects and unstable Bluetooth connections between mug and app.
Repeated pairing failures and the need to re-pair the mug with almost every use.
Login/sign-in is cumbersome (multiple emails/codes) and users are often logged out.
Software updates frequently cause issues, breaking pairing or causing crashes.
App behavior like calling home in the background and unnecessary connectivity chatter can be problematic.

2026-06-13	Fa*****	Edit June 2026: same thing as my early 2024 review -> Pixel 8 - stock. No matter how many times I reset, uninstall/re-install, make sure nothing's blocked or permissions missing it just doesn't work 90% of the time. The other 10% is utterly random when I try after a while and for some reason works, however the next time I launch the app, no linger works.

2026-06-08	Li*****	Mug stopped pairing inexplicably after 1.5 years. Mug is not broken and paired with a third-party app without issue.
