This source's evidence 🎬

Source verdict

After extensive testing, the reviewer concludes that the Noise REP has good hardware but suffers from significant software issues, including missing features, inaccurate metrics (like calories and sleep stages), and a poor user experience due to app glitches, mandatory syncing, lack of offline use, and even in-app ads. While hopeful for future updates, the current performance is disappointing, especially compared to competitors in its price range.

About this source

The review covers the Noise REP fitness band, evaluating its performance over 20 days. It extensively tests various data metrics like heart rate tracking, sleep monitoring, and recovery, comparing them against reference devices such as the WHOOP band and Polar H10 chest strap. The review also assesses the device's design, comfort, battery life, and overall user experience, including the companion application.

Review notes

The Noise REP is a disappointing fitness tracker that fails to live up to expectations as an affordable alternative to premium bands like WHOOP. While its heart rate tracking data improved significantly after an update, matching Polar H10 data up to 98%, the calorie counter showed large discrepancies compared to WHOOP and Polar H10, and auto workout tracking for walking sessions was consistently missed. Sleep monitoring proved inconsistent across deep and REM sleep metrics, and the companion app suffered from persistent syncing issues, a lack of offline workout functionality, and occasional ads. If you are seeking reliable and comprehensive health tracking with a smooth app experience, look elsewhere. If you prioritize budget and only need basic, mostly accurate heart rate data with other metrics being less critical, this device might be a hesitant consideration.

What the reviewer liked

  • Lightweight and comfortable for 24/7 wear
  • Heart rate tracking is accurate, matching Polar H10 data after a recent update (90-98% accuracy)
  • Simple and clean design approach
  • Easy capsule removal for charging

What the reviewer criticised

  • Calorie counter is highly inaccurate compared to WHOOP and Polar H10
  • Auto workout tracking is inconsistent, often missing walking sessions
  • Sleep monitoring (deep sleep, REM sleep) is inconsistent compared to Apple Watch and WHOOP
  • Skin temperature readings are inconsistent
  • VO2 Max metric is listed on the website but missing from the app
  • SpO2 feature is "coming soon" but not active
  • Companion app has glitches, sometimes failing to open the workout section
  • Requires internet connection to start workouts due to constant syncing
  • Application displays occasional ads, even in notifications
  • Magnetic charging connection could be stronger
  • Battery life is short, requiring charging every 5-6 days

Structured claims

The Noise REP's heart rate tracking improved significantly after an update, showing 90-98% accuracy when compared to the Polar H10 chest strap during cycling workouts, though initial sessions had some inconsistencies.

measurement_claimstrong

The Noise REP's calorie counter shows a significant difference compared to both WHOOP and Polar H10, often displaying much higher calorie burn data than other reliable devices.

measurement_claimstrong

The device's auto workout tracking feature is unreliable, failing to record common activities like walking sessions that were successfully tracked by other devices like WHOOP.

reviewer_claimstrong

The skin temperature metric provided by the Noise REP is inconsistent, showing fluctuations that make it unreliable compared to other metrics.

reviewer_claimmoderate

The Noise REP showed slightly different resting heart rate (RHR) and Heart Rate Variability (HRV) data on some days when compared to the WHOOP band.

comparison_claimmoderate

Despite being listed on the website, the VO2 Max metric could not be found within the Noise REP application by the reviewer.

specification_claimstrong

The SpO2 (blood oxygen) metric is listed as "coming soon" in the Noise REP app, indicating it is not yet functional or fully implemented.

specification_claimmoderate

While total sleep duration was consistent, the Noise REP showed significant and inconsistent differences in deep and REM sleep tracking when compared to Apple Watch and WHOOP.

comparison_claimstrong

The Noise REP's recovery score was initially 10-15% lower than WHOOP's, but after a software update, the recovery metrics improved significantly and now appear "very correct".

comparison_claimstrong

The Noise REP companion app has several user experience issues, including the workout section occasionally failing to open, mandatory syncing on app launch that delays workout initiation, and the inability to start workouts without an internet connection.

reviewer_claimstrong

The Noise REP application occasionally displays ads both within the app interface and in notifications, which the reviewer finds unacceptable for a paid device.

Evidence items

Battery Life

reviewer_claimneutralt=02:17–02:24

The reviewer reported needing to charge the device every 5-6 days based on their usage.

Initial Heart Rate Tracking Accuracy

comparisonmixedt=04:30–04:50

In initial cycling workouts, the Noise REP's heart rate data was inconsistent for the first 10 minutes compared to Polar H10, but tracked accurately for the remainder of the sessions.

Post-Update Heart Rate Tracking Accuracy

measurement_testpositivet=04:52–05:15

After a recent update, the Noise REP's heart rate data was quite accurate, matching Polar H10 data by roughly 90-98% from start to end during cycling sessions.

Calorie Tracking Inaccuracy

comparisonnegativet=05:15–06:00

The Noise REP's calorie counter showed a significant difference compared to WHOOP and Polar H10, with Noise often displaying over 1200 calories burnt while WHOOP and Polar H10 data matched each other on Strava.

Auto Workout Tracking Unreliable

comparisonnegativet=06:07–06:45

The auto workout tracking feature was unreliable; none of the reviewer's walking sessions were recorded by the Noise REP app, while WHOOP successfully tracked them.

Skin Temperature Inconsistency

comparisonnegativet=06:55–07:20

After a 7-day comparison with WHOOP, most health metrics were fine, but the Noise REP's skin temperature readings felt inconsistent, fluctuating up and down.

RHR and HRV Discrepancies

comparisonmixedt=07:20–07:35

The reviewer observed that resting heart rate (RHR) and Heart Rate Variability (HRV) data showed some differences compared to WHOOP on certain days.

VO2 Max Feature Not Found in App

reviewer_claimnegativet=07:35–08:10

The reviewer was unable to find the VO2 Max metric within the Noise REP application, despite the feature being listed on the product's website.

SpO2 Feature Pending

specification_claimneutralt=08:30–08:40

The SpO2 metric is currently showing as 'coming soon' in the app, making its accuracy difficult to assess.

Sleep Stage Tracking Inconsistencies (Day 1)

comparisonmixedt=09:40–10:30

On Day 1, Noise REP's total sleep duration was fine, but deep sleep and REM sleep differed from both Apple Watch and WHOOP. Light sleep matched Apple Watch, and awake time was close to WHOOP.

Overall Sleep Tracking Inconsistency

comparisonnegativet=10:55–11:50

The overall average of sleep data showed that while total sleep duration was consistent, other metrics like deep and REM sleep had significant and inconsistent differences when compared to Apple Watch and WHOOP.

Recovery Score and Post-Update Accuracy

comparisonmixedt=12:00–12:35

Initially, Noise REP's recovery score was 10-15% lower than WHOOP's. After an update, the sleep metric increased by 10%, and recovery scores now appear 'very correct'.

App Glitch: Workout Section Not Opening

reviewer_claimnegativet=13:58–14:15

The reviewer encountered a glitch where the workout section in the app would sometimes fail to open after attempting to load.

App Limitations: Mandatory Sync and No Offline Workouts

hands_on_demonegativet=14:15–15:20

The app enters syncing mode upon opening, preventing workout initiation until sync completes. Additionally, workouts cannot be started without an internet connection, which the reviewer experienced during cycling.

Ads within Noise REP App
