Based on a review by Rohit Raj Gupta (accessed 2026-08-31).
Based on this review alone: skip it — calorie counter is highly inaccurate compared to whoop and polar h10, unless lightweight and comfortable for 24/7 wear is your only priority.
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.
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.
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.

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

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.
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.
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.
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.
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.
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.

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.
specification_claimneutralt=08:30–08:40
The SpO2 metric is currently showing as 'coming soon' in the app, making its accuracy difficult to assess.
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.
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.
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'.
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.
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.
visual_inspectionnegativet=15:20–15:55
The reviewer observed occasional ads within the Noise REP application and its notifications, deeming them unacceptable for a device costing 10,000 rupees.
After an initial period of inconsistency, a recent update significantly improved the Noise REP's heart rate tracking accuracy, achieving 90-98% agreement with the Polar H10 chest strap during cycling workouts.
The Noise REP's calorie counter showed significant discrepancies, often displaying much higher calorie burn numbers compared to both WHOOP and Polar H10, which themselves matched each other. The reviewer noted this as a major area for improvement.
The reviewer found the auto workout tracking to be "hit or miss," with the device completely failing to record walking sessions of various durations, despite them being tracked successfully by WHOOP.
While the Noise REP consistently tracked total sleep duration, its readings for deep sleep and REM sleep showed significant and inconsistent differences when compared to Apple Watch and WHOOP, indicating a need for improvement in sleep stage accuracy.
Based on the reviewer's experience, the Noise REP needed to be charged approximately every five to six days, indicating a moderate battery life.
The Noise REP app experiences glitches where the workout section sometimes fails to open. More critically, it forces a syncing mode upon opening, preventing workout initiation until complete, and does not allow workouts to be started without an internet connection. The reviewer also observed occasional in-app advertisements.
The reviewer could not find the VO2 Max metric in the Noise REP app, despite it being featured on the product's website. Additionally, the SpO2 (blood oxygen) metric is currently displayed as "coming soon," indicating it is not yet available for use.
85/100 source quality
This review provides an in-depth look at the Noise REP fitness band, detailing its heart rate tracking accuracy against a Polar H10 chest strap and its sleep and recovery metrics compared to the WHOOP band over a 20-day period. The reviewer found promising improvements in heart rate tracking after an update but noted significant inaccuracies in calorie tracking and inconsistencies in sleep stage detection. The accompanying app was criticized for issues like unreliable auto workout tracking, mandatory online syncing, and occasional advertisements, despite a generally comfortable design and decent battery life.
