Compare Withings ScanWatch 2 vs Huawei Watch Fit 4

Reviewers found auto-detection useful in concept but inconsistent in practice, with some praising automatic walking/running recognition and others reporting flaky, false, or missing detection.

Workout auto-detection is directly mentioned as handy, though only one review discusses it and notes battery tradeoffs around keeping it enabled.

The broader ecosystem is strongest for people already using Withings or health-platform integrations, though app changes and paid layers made the experience less universally satisfying.

Reviewers describe the core Huawei feature set as useful, but the app ecosystem is limited compared with fuller smartwatch platforms.

Band impressions were split: several reviewers liked the fluoroelastomer or silicone strap, while others found it itchy, slippery, or poorly fitted enough to replace.

Bands and strap hardware draw mostly positive comments, with easy removal, secure fit, and good strap quality across several reviews.

Battery life was the most consistently praised attribute, with reviewers regularly getting multiple weeks and sometimes close to a month between charges.

Battery life is one of the strongest recurring positives, with reviewers reporting roughly a week or more depending on always-on display and usage.

Blood oxygen support was widely noted as a useful health feature, though reviewers varied from calling readings accurate to noting occasional inconclusive or basic behavior.

SpO2 tracking is present and repeatedly included among the watch's health metrics, with reviewers treating it as part of a solid wellness set.

Bluetooth-connected use is functional for phone pairing and connected GPS, but the watch depends on the phone/app rather than offering a fully independent connection experience.

Bluetooth support is generally positive for calls, external sensors, and earbuds, with Bluetooth 5.2 and pairing use cases called out.

Brightness was generally adequate and sometimes praised, but one reviewer found the small screen harder to see in bright light.

Brightness is a clear strength, with multiple reviewers highlighting the 2,000-nit peak and comfortable visibility.

Build quality was a clear strength, with repeated praise for the stainless case, solid feel, and premium analog-watch construction.

Build quality is praised as premium for the price, with aluminum construction and lightweight feel repeatedly mentioned.

The crown-based controls were usually seen as simple and tactile, though the one-button design can feel limiting compared with touch-first smartwatches.

The crown and button setup is positively described, with reviewers finding the controls more integrated and handy for scrolling.

Call handling is minimal: reviewers repeatedly noted that the watch can show or alert for calls but cannot take or answer them from the wrist.

Call handling is good for a budget smartwatch, especially speaker loudness and Bluetooth calling, though one review notes clarity is not the crispest.

Calorie data appears as part of workout or activity summaries, but reviewers treated it as basic supporting information rather than a standout coaching metric.

Calorie tracking is only lightly supported, but one review values seeing calories alongside steps and heart rate on the watch face.

Charging convenience was mixed: the newer cradle is more secure for some reviewers, while others found the proprietary dock flimsy, fiddly, or clunky.

Charging convenience is mostly positive thanks to fast top-ups, secure magnetic charging, and wireless charging mentions, but proprietary charging is a caveat.

Charging speed was consistently acceptable, with reviewers generally reporting roughly 90 minutes to two hours for a full charge.

Charging speed is consistently strong, with several reviews citing a full charge around 75 minutes or a meaningful 30-minute top-up.

Coaching features mostly live in the app or Withings+; reviewers liked some gentle prompts and sleep tips but often questioned the subscription's value.

Coaching features are useful, from movement prompts to warmups, cooldowns, training plans, and non-generic feedback.

Comfort was usually good for all-day wear, helped by the lighter hybrid design, though sleep comfort and strap fit were not consistent for everyone.

Comfort is a major positive, with reviewers repeatedly describing the watch as light, slim, and wearable all day.

The companion app drew mixed reviews: it can show detailed health data and reports, but reviewers also criticized glitches, busy layout, and unclear insights.

The Huawei Health app is feature-rich and can be easy to use, but several reviewers criticize clutter or bloat.

Contactless payments are effectively absent, with multiple reviewers explicitly noting no payment support.

Contactless payment support is weak because NFC or payment support is limited by region and availability.

Cross-platform support is a strength, with reviewers citing iOS, Android, Apple Health, Google Fit or Health Connect compatibility.

Cross-platform compatibility is acceptable across Android and iOS, but reviewers flag missing iOS features such as Petal Maps or music support.

Customization is decent for bands, sizes, colors, menus, and app-controlled screens, but limited for watch faces and deeper interface changes.

Customization is a strength, including watch-face changes, widgets, button mapping, and quick band swaps.

Display quality is sharp and readable for its size, but the tiny grayscale screen remains a major limitation for messages and rich fitness data.

Display quality is strongly praised, with reviewers repeatedly calling out the AMOLED screen, clarity, resolution, and visual punch.

Durability was praised thanks to sapphire glass, stainless steel, water resistance, and reports of no visible scratches after use.

Durability appears good for everyday use, with Gorilla Glass, water exposure, and daily wear references supporting a positive score.

ECG functionality was one of the strongest health features, repeatedly described as medical-grade, easy to use, FDA-approved, or shareable with doctors.

ECG functionality is a clear omission from the regular Fit 4, appearing as a Pro-model advantage rather than a base-model feature.

Fit depended heavily on wrist size and strap choice: some reviewers found it lighter and comfortable, while others found the case or supplied strap awkward.

Fit is positive, with strap security, wrist-size accommodation, and a balanced dial size appearing across reviews.

Fitness tracking accuracy was mixed, with some strong heart-rate and pace comparisons but enough missing, incomplete, or high-intensity issues to keep it from sports-watch territory.

Fitness tracking accuracy is generally strong, especially treadmill, GPS, route, and workout-map evidence, with only minor caveats in some contexts.

GPS was a recurring weakness because most reviewers reported no built-in GPS and reliance on phone-connected GPS, despite some acceptable connected-GPS results.

GPS accuracy is one of the best-supported strengths, with dual-band GPS, fast lock, offline maps, and accurate outdoor tracking discussed repeatedly.

Health tracking accuracy was broadly promising for core metrics, but confidence varied due to sleep, heart-rate, and app-data inconsistencies.

Health tracking accuracy is broadly positive for everyday use, especially heart rate and health insights, while reviewers still avoid medical-grade claims.

Heart-rate accuracy was inconsistent: some tests matched straps or other devices closely, while others found daytime, swim, or high-intensity readings unreliable.

Heart rate accuracy receives strong support, including comparisons to other watches and a Polar H10 chest strap, with one review noting slower mid-exercise updates.

Materials quality was consistently strong, with repeated praise for stainless steel, sapphire glass, premium build materials, and high-grade construction.

Materials quality is consistently praised, especially the aluminum or metal body and premium construction for the price.

Menu navigation was understandable once learned, but reviewers often described scrolling, submenus, or crown-only navigation as clunky or tedious.

Menu navigation is well supported by list/grid views, crown scrolling, quick workout access, and smooth app layout options.

Music controls are absent, and reviewers repeatedly mentioned the lack as part of the watch's limited smartwatch feature set.

Music controls are useful for phone playback and on-watch playback, though platform support can vary.

Onboard music storage is not supported; the only direct reviewer mention grouped offline music among missing smartwatch features.

Onboard music storage is a positive where supported, with reviewers noting MP3 copying and internal music storage.

The HealthSense software platform was presented as modern and health-focused, supporting the newer temperature and wellness tracking features.

The operating system experience feels polished and Apple-Watch-like in several reviews, though permissions and platform gaps remain tradeoffs.

Outdoor visibility was serviceable overall, with some reviewers calling the display readable outdoors and others finding bright-light viewing harder.

Outdoor visibility is a major strength, with multiple reviewers saying the screen remains visible or clear in sunlight.

Pairing and connection reliability were praised in the reviews that discussed setup, including instant pairing, straightforward setup, and a rock-solid app connection.

Pairing reliability is only lightly supported and somewhat mixed, with one review mentioning rare disconnects over three weeks.

Recovery insights are a meaningful upgrade, especially through HRV and temperature tracking, though some recovery-related features or analysis remain basic or subscription-tied.

Recovery insights are present through recovery time, training load, and training index metrics.

Reliability was a concern in several reviews, especially around app syncing, missed notifications, sleep misclassification, and confidence in sensor output.

Reliability is mixed but more positive overall, with one review flagging occasional disconnects and another recommending it as reliable.

Safety features are a strength, with reviewers citing temperature alerts, overheating warnings, sleep-apnea detection, AFib/ECG support, and related health alerts.

Safety-adjacent navigation features are supported through route-back and back-to-start functions rather than emergency features.

Size options were well covered, with repeated mentions of 38mm and 42mm cases, though reviewers differed on which size best fit smaller wrists.

Style and design are widely praised, with reviewers describing the watch as elegant, premium, stylish, and Apple Watch-like.

Sleep tracking accuracy was mixed: some reviewers found it comparable or useful, while others reported missed sleep, overestimates, or poor handling of wake periods.

Sleep tracking accuracy is positive overall, with reviews comparing sleep duration, scores, stages, and detection to other wearables.

Smartphone notifications are limited by the small scrolling display and inconsistent delivery, useful for quick glances but poor for long messages or interaction.

Notifications are useful, including app selection, quick replies, and message replies, but iOS reply limitations reduce the score.

Smartwatch features are intentionally sparse, with reviewers repeatedly describing the ScanWatch 2 as more watch or tracker than full smartwatch.

Smartwatch features are broad for the price, but the watch is still strongest as a fitness tracker rather than a complete smartwatch.

Software smoothness received limited direct evidence, with one reviewer finding the app decent but inconsistent enough to need fixes.

Software smoothness is a strong point in several reviews, with fluid interfaces, 60 Hz refresh, and smooth animations repeatedly praised.

Step counting was generally acceptable but not perfectly aligned with other devices, with reviewers describing it as precise, conservative, or occasionally uneven.

Step counting accuracy is directly praised in one review as matching the prior Fit line's strong performance.

Stress tracking is indirect rather than a full stress platform, relying on HRV, recovery, and breathing data while lacking richer readiness-style stress features.

Stress tracking is well represented through HRV, all-day stress analysis, emotional well-being, and mood-pattern tracking.

Style and design were the strongest consensus positives, with reviewers repeatedly praising the traditional analog look, premium elegance, and subtle hybrid design.

Design is one of the clearest strengths, with repeated praise for premium looks, slimness, and everyday wearability.

Third-party app support is essentially absent on the watch itself, even though the phone app can share health data with outside platforms.

Third-party app support is limited, with AppGallery described as scaled back and one of the main disappointments.

Touchscreen responsiveness scores low because the ScanWatch 2 does not have a touchscreen; interaction relies on the crown and small display.

Touchscreen responsiveness is generally good, especially on the AMOLED touchscreen, though one swimming test found touch use impractical under water.

The user interface is simple and elegant for basic health data, but constrained by the small screen and crown-only interaction.

The user interface is mostly praised as fluid, intuitive, and smooth, with some permission and organization caveats elsewhere.

Value for money was mixed to weak: reviewers liked the premium health-watch concept but often questioned the price versus smarter or cheaper alternatives.

Value for money is one of the strongest consensus points, with reviewers repeatedly calling the watch affordable, good value, or hard to beat.

Voice assistant quality is weakly supported and negative, because one review says the assistant needs a Huawei phone.

The watch face quality was praised for its traditional analog appearance, secondary step dial, and discreet hybrid integration.

Watch face quality is good, with many attractive faces, but paid faces and regional app-store differences create some caveats.

Water resistance is a clear plus, with reviewers repeatedly citing 5ATM protection, swimming, shower, or 50-meter suitability.

Water resistance is generally positive for swimming and daily wet use, though hot water and Pro diving differences remain caveats.

Wellness insights are broad and health-focused, but reviewers split on whether the free app and Withings+ make the data actionable enough.

Wellness insights are a strength, especially health insights, emotional well-being, breathing prompts, and mental-wellness trends.

Wi-Fi connectivity is a limitation because one review says Wi-Fi is added by the Pro model, not the regular Fit 4.

Workout variety is respectable for casual users, with 30 to around 50 activities mentioned, but the depth and athlete-focused metrics remain limited.

Workout variety is very broad, with 100-plus workout modes and many sport profiles, though one review still wanted a fuller list.
