Product 1: Withings ScanWatch Nova
4.5

The broader Withings ecosystem is a recurring strength, especially for users pairing the watch with scales, thermometers, or other Withings health devices.

Product 2: Garmin Forerunner 570
3.7

The app ecosystem is useful but not expansive. Reviewers mention ConnectIQ apps and data fields, while also noting that Garmin’s ecosystem feels more limited than watchOS or Wear OS.

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: Garmin Forerunner 570
4.5

Band quality is good, with soft silicone straps and positive comments about long-term wear and durability.

battery life
Product 1: Withings ScanWatch Nova
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: Garmin Forerunner 570
3.2

The watch includes blood-oxygen-related health sensing, with reviewers mentioning a pulse oximeter and overnight blood-oxygen or saturation tracking as part of the health stack.

Bluetooth connectivity
Product 1: Withings ScanWatch Nova
3.0

Bluetooth-linked features work, but connectivity is not flawless. One review mentioned the app losing connection during workouts.

Product 2: Garmin Forerunner 570
4.3

Bluetooth support is functional for phone-linked features and external sensor pairing, including Bluetooth and ANT+ accessory support.

brightness
Product 1: Withings ScanWatch Nova
4.0

Product 2: Garmin Forerunner 570
4.6

Build quality feels premium for the line, with one review explicitly describing it as a high-quality watch.

button controls
Product 1: Withings ScanWatch Nova
3.0

Physical controls get the job done, but reviewers also mentioned awkward crown placement or bezel resistance.

Product 2: Garmin Forerunner 570
4.7

Button controls are one of the watch’s practical strengths. Reviewers like the five-button layout and say it works reliably when touch is less convenient.

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.

Product 2: Garmin Forerunner 570
4.0

Call support is a useful upgrade rather than a must-have killer feature. Reviewers generally found wrist calls workable and clear enough when paired to a phone.

calorie tracking usefulness
Product 1: Withings ScanWatch Nova
4.5

One reviewer specifically found estimated calories burned far more accurate than on Fitbit, suggesting the calorie data can be useful for day-to-day activity review.

Product 2: Garmin Forerunner 570
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.

Product 2: Garmin Forerunner 570
2.8

Charging convenience is less impressive. Reviewers specifically wanted wireless charging and also called out the proprietary cable setup.

charging speed
Product 1: Withings ScanWatch Nova
3.4

Charging is usually described as taking about two hours, though at least one review reported a notably faster full recharge.

Product 2: Garmin Forerunner 570
4.5

Charging speed is fine in practice, with one long-term reviewer saying it can top up from empty to full during a shower.

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.

Product 2: Garmin Forerunner 570
4.6

Coaching features are well developed, especially for runners and triathletes. Garmin Coach plans, daily suggestions, and structured guidance were consistently praised.

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.

Product 2: Garmin Forerunner 570
4.6

Comfort is a major plus. Across sizes and use cases, reviewers repeatedly say the watch is easy to wear for workouts, daily use, and even overnight.

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: Garmin Forerunner 570
4.0

Garmin Connect is usually viewed positively for depth and data richness, though the new subscription layer is a recurring annoyance in the reviews.

contactless payments
Product 1: Withings ScanWatch Nova
1.0

Review coverage explicitly notes that digital payment support is not included, so contactless payments are a known weakness.

Product 2: Garmin Forerunner 570
4.3

NFC payments are available, giving the watch a useful everyday smartwatch feature beyond training tools.

cross-platform compatibility
Product 1: Withings ScanWatch Nova
5.0

Cross-platform support is strong, with explicit Android and iOS compatibility in the reviews.

Product 2: Garmin Forerunner 570
4.4

customization options
Product 1: Withings ScanWatch Nova
4.2

Reviews note useful customization for screen order, workout order, and display functions, even if the overall smartwatch feature set stays simple.

Product 2: Garmin Forerunner 570
4.5

Customization is a strength. Reviews mention editable glance folders, assignable shortcuts, and flexible watch-face or data layout changes.

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: Garmin Forerunner 570
4.8

Display quality is excellent. Reviewers repeatedly call the AMOLED screen brighter, sharper, clearer, and more vivid than the previous generation.

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: Garmin Forerunner 570
4.6

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: Garmin Forerunner 570
1.5

ECG is a clear miss. Reviewers repeatedly call out that the Forerunner 570 lacks ECG despite using Garmin’s newer sensor hardware.

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: Garmin Forerunner 570
4.8

Fit is excellent when sized correctly, with reviewers describing the watch as secure, flush on the wrist, and almost second-skin-like.

fitness tracking accuracy
Product 1: Withings ScanWatch Nova
4.0

Fitness tracking is generally credible for everyday use, but reviewers frame the Nova as stronger for broad health tracking than for detailed sport analysis.

Product 2: Garmin Forerunner 570
4.7

Fitness tracking is broadly praised, with one review calling the core tracking accuracy second to none for the watch’s main sports focus.

GPS accuracy
Product 1: Withings ScanWatch Nova
3.3

Connected GPS can track workouts accurately when paired with a phone, but one review also reported gaps after the app lost connection to the watch.

Product 2: Garmin Forerunner 570
4.8

health tracking accuracy
Product 1: Withings ScanWatch Nova
4.5

Reviews repeatedly describe the recorded health data as accurate or comparable to other smartwatches and even medical devices, though some sleep and workout details can still be imperfect.

Product 2: Garmin Forerunner 570
4.3

Product 2: Garmin Forerunner 570
4.6

Heart-rate tracking is a major strength. Multiple reviewers say it stays close to chest straps, performs well in intervals, and is one of Garmin’s better recent sensors.

materials quality
Product 1: Withings ScanWatch Nova
4.5

Stainless steel, sapphire, and other premium materials are repeated selling points across reviews.

Product 2: Garmin Forerunner 570
4.4

Material choices are a step up from older mid-range Forerunners, especially the aluminum bezel and sturdier-feeling case construction.

menu navigation
Product 1: Withings ScanWatch Nova
4.5

Crown-based menu navigation is widely praised as easy and intuitive, especially for a watch without touchscreen input.

Product 2: Garmin Forerunner 570
4.6

Menu navigation is easy to learn and generally straightforward, helped by the refreshed layout and button-plus-touch design.

music controls
Product 1: Withings ScanWatch Nova
1.0

Music controls are explicitly described as absent in review coverage.

Product 2: Garmin Forerunner 570
4.1

Music controls are present and usable, including the ability to check what is playing from services like Spotify.

onboard music storage
Product 1: Withings ScanWatch Nova
No score yet
Product 2: Garmin Forerunner 570
4.0

Onboard music storage is useful but not generous. Reviews note 8GB of storage and MP3 support, with some calling the capacity a bit stingy.

operating system experience
Product 1: Withings ScanWatch Nova

3.5

Notifications work, but the experience is mixed. Some reviewers had smooth delivery, while others found text truncated or alerts too persistent on screen.

smartwatch features
Product 1: Withings ScanWatch Nova
3.0

Smartwatch features are intentionally basic, covering essentials like alerts, timers, alarms, and stopwatches rather than a full smartwatch experience.

Product 2: Garmin Forerunner 570
4.3

stress tracking
Product 1: Withings ScanWatch Nova
No score yet
Product 2: Garmin Forerunner 570
4.2

Stress is part of the recovery picture rather than a headline feature, with one reviewer specifically noting that stress levels feed into the watch’s overall readiness guidance.

style and design
Product 1: Withings ScanWatch Nova
4.9

4.5

Third-party service support is solid for a sports watch, with repeated mentions of Spotify, Deezer, Amazon Music, and YouTube Music support.

touchscreen responsiveness
Product 1: Withings ScanWatch Nova
1.0

4.5

Touch response is consistently described as responsive and easy to use, especially alongside the physical-button setup.

user interface
Product 1: Withings ScanWatch Nova

voice assistant quality
Product 1: Withings ScanWatch Nova
No score yet
Product 2: Garmin Forerunner 570
4.0
