The app ecosystem is a strength, with Samsung, Google, and third-party apps all represented on the watch.

band quality
Product 1: Withings ScanWatch Nova
4.0

The included bands are generally liked, especially the silicone and sport options, though the metal band can be trickier to fine-tune.

Product 2: Samsung Galaxy Watch 7
4.0

Band quality is generally good and comfortable for exercise, though at least one reviewer found reattachment a bit fiddly.

battery life

4.4

Battery life is a major strength, with most reviewers seeing multi-week endurance, though heavier workout or connected-GPS use can shorten it.

Product 2: Samsung Galaxy Watch 7

Battery life remains the biggest tradeoff: some reviewers reached around a day or 1.5 days, but AOD, GPS, and workouts often push it toward daily charging.

blood oxygen tracking
Product 1: Withings ScanWatch Nova
3.9

SpO2 tracking is broadly seen as useful and easy to access, though one reviewer needed a few tries before the reading worked properly.

Product 2: Samsung Galaxy Watch 7

4.0

The hardware buttons are simple and useful, giving quick access to core functions like Home and wallet features.

call handling
Product 1: Withings ScanWatch Nova
2.0

Call handling is minimal. Reviewers mention call alerts or caller info, but calls still route through the phone and full phone-call support is missing.

Call handling is solid, with support for answering calls from the watch and gesture shortcuts that make hands-busy interactions easier.

calorie tracking usefulness
Product 1: Withings ScanWatch Nova

Product 2: Samsung Galaxy Watch 7
No score yet

Product 1: Withings ScanWatch Nova
2.8

The charger works, but reviewers repeatedly criticize its cheap feel, awkward design, or lack of wireless convenience.

coaching features
Product 1: Withings ScanWatch Nova
3.8

Coaching features exist mainly through Withings+, including goals, workouts, meal plans, and guided programs, so the coaching layer depends on the subscription.

4.0

The watch offers meaningful coaching tools, including wellness tips, health guidance prompts, and access to free workout content.

comfort
Product 1: Withings ScanWatch Nova
4.3

Comfort is generally very good, especially with lighter or sport bands, though one review had real issues with the metal band pinching or fitting poorly.

companion app quality
Product 1: Withings ScanWatch Nova
4.4

The companion app is consistently praised for presenting data clearly, neatly, and in a way that is easy to understand.

Product 2: Samsung Galaxy Watch 7

Samsung’s companion apps add a lot of context and value, though the overall setup can feel a bit app-heavy.

contactless payments
Product 1: Withings ScanWatch Nova

Product 2: Samsung Galaxy Watch 7
4.5

Customization is excellent, from watch faces and tiles to custom workout pages and other configurable on-watch elements.

display quality
Product 1: Withings ScanWatch Nova
4.2

The small grayscale OLED is generally sharp and legible, though its size naturally limits how much information it can show.

Product 2: Samsung Galaxy Watch 7
4.5

Display quality is excellent, with sharp, colorful AMOLED panels earning praise across reviews.

durability
Product 1: Withings ScanWatch Nova
4.5

Early durability impressions are strong, including one reviewer whose watch still looked pristine after rough travel and family handling.

Product 2: Samsung Galaxy Watch 7
4.5

Durability is a major plus thanks to IP68, 5ATM, and MIL-STD protection aimed at real everyday wear.

ECG functionality
Product 1: Withings ScanWatch Nova
4.3

ECG is one of the watch’s standout features, with multiple reviewers calling it easy to use and one noting that it agreed with a medical examination.

Product 2: Samsung Galaxy Watch 7
4.2

ECG support is a clear strength, but reviewers repeatedly note that access is limited by Samsung-phone requirements and regional availability.

fit
Product 1: Withings ScanWatch Nova
3.5

Fit can be excellent once adjusted, but metal-band sizing is not foolproof and may take some patience.

Product 2: Samsung Galaxy Watch 7
3.8

Fit is mostly good thanks to the two size options, but comfort and sensor shape can still vary depending on wrist size.

fitness tracking accuracy
Product 1: Withings ScanWatch Nova

General fitness tracking is strong, with reviewers calling activity tracking accurate and highlighting the watch’s fitness focus as a core strength.

GPS accuracy

Reviewers describe the health-tracking package as strong and feature-rich, with broadly reliable sensor data and lots of contextualized metrics.

heart rate accuracy
Product 1: Withings ScanWatch Nova
4.5

Heart-rate tracking is a clear strength, with one reviewer saying average heart rate deviated by only one point and another calling the heart-rate results accurate against other smartwatches.

Product 2: Samsung Galaxy Watch 7

3.2

Outdoor visibility is mixed. Some reviewers found the display readable in sunlight, while others wanted better direct-sun performance or less reflection.

smartphone notifications
Product 1: Withings ScanWatch Nova

Third-party app support is good for major apps, but broader platform integrations beyond a few services are still limited.

touchscreen responsiveness
Product 1: Withings ScanWatch Nova
1.0

workout tracking variety
Product 1: Withings ScanWatch Nova
