4.5

Data control received positive notes where reviewers valued Health Connect portability and easy deletion of cycle-tracking data.

Pros: software smoothness, comfort

Cons: battery life, GPS accuracy

#2 Polar Street X
4.5

Data privacy was praised by one reviewer as a reason to consider Polar, especially for European users.

Pros: value for money, flashlight usefulness

Cons: user interface

#3 Garmin Forerunner 255
4.3

Data privacy had limited positive support from a walkthrough praising notification privacy mode.

Pros: GPS accuracy, battery life

Cons: heart rate accuracy, recovery insights

#5 Garmin Tactix 8

Pros: battery life, durability

Cons: value for money, band quality

#6 Garmin Bounce 2

The closed contact system limits strangers, apps, and social media, which gives parents more control than a smartphone. Continuous child-location data still requires trust in Garmin’s handling of sensitive information.

Pros: smartwatch features, safety features

Cons: value for money, call handling

Pros: battery life, comfort

Cons: value for money, charging speed

#8 Apple Watch Series 12
2.7

Privacy is the clearest source of disagreement. Some reviewers trust Apple’s on-device architecture, while others remain deeply uncomfortable with always-listening audio features and their effect on nearby people.

Pros: value for money, heart rate accuracy

Cons: data privacy

#9 Apple Watch Ultra 4
2.7

Privacy is the most divisive new area. Apple's on-device protections earn praise, but Siri Recap and other always-listening features raise repeated concerns about bystander consent and ambient recording.

Pros: battery life, value for money

Cons: data privacy, comfort

#10 Coros Nomad
2.0

Activity-sharing privacy has an important caveat: one reviewer wanted a way to hide start and end locations before sharing. That missing control can matter for routes that begin at home.

Pros: mapping and navigation, value for money

Cons: smartwatch features, contactless payments

#11 Google Pixel Watch 5
2.0

AI-powered health features raise legitimate privacy concerns because increasingly personal health information can be exposed to broader assistant functionality.

Pros: software smoothness, style and design

Cons: value for money, wellness insights

#12 CMF Watch Pro 2
1.0

Data privacy and device security were clear weaknesses because reviewers noted the lack of a PIN, pattern, or lock mode.

Pros: value for money, battery life

Cons: GPS accuracy, sleep tracking accuracy
