To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I love this! Received this and used this today for my workout. Much more accurate compared to another tracker that I had been using. The only thing that could be confusing is the calories in and calories out tracker.
