The interface drew repeated criticism for feeling dated, not polished enough, or less intuitive than it should be on the large display.
workout tracking variety
Fitbit Ace LTE
2.3

4.2
Calling and messaging were widely praised as useful and clear, but app-based call handling and occasional call failures kept the score from being perfect.
Garmin Venu X1
2.8
Bluetooth call quality was acceptable in one review, but another found app-based calling limited and unable to handle a Teams call from the wrist.
mapping and navigation
Fitbit Ace LTE
3.5
Mapping and navigation are useful when location works, with praise for Google Maps, but reviewers wanted geofencing and one tester saw locate failures.

3.2
Garmin’s own ecosystem was praised by one reviewer, while others noted it lacks Apple-style integration and broader smart-app depth.
reliability
Fitbit Ace LTE
3.2

Water resistance was adequate for swimming and showers, but reviewers repeatedly noted the 50m rating and lack of diving or stronger Ultra credentials.
smartwatch features
Fitbit Ace LTE
4.1
As a smartwatch, the Ace LTE feels robust and kid-focused, but it is intentionally limited compared with fuller adult-style watches.
Garmin Venu X1
3.1
Smartwatch features were viewed as useful for a Garmin but still short of true smartwatch platforms, especially Apple and Wear OS.
contactless payments
Fitbit Ace LTE
2.3

4.0
The watch appears to reward normal movement automatically during daily play, though the evidence is limited to one reviewer’s description of points being earned while active.
