Biostrap Vs Whoop 4.0: How do the two differ?

What’s the difference between them? Read on to find out.

Appearance, Design, and Comfort

Both Biostrap and Whoop are available in the form of a fitness band made of plastic-like material attached to a strap. Although Whoop can be placed on the triceps or forearm, they’re designed to be worn on the wrist. The Biostrap’s core unit measures 91×91 cm, while the Whoop is a bit larger but thinner. The other main difference is that the Biostrap comes with an optional shoe pod that can be attached to our sneakers for activity tracking.

Both devices are supposed to be worn around the clock, so they have impressive water resistance. Whoop 4.0 has 3 ATMs, while Biostrap 5 ATM rating. Both of them lack buttons or displays, so you need a smartphone app to view the insights and statistics.

Additionally, they have no vibrations for notifications since their main goal is to keep things simple, preserve the battery, and reduce distractions.

Activity and Workout Tracking

As stated earlier, Biostrap comes in the form of an optional foot pod and wristband. However, the shoe pod is only applied in activity classification. The Whoop alternative collects crucial data like active calories, sleep, steps, heart rate viability, heart rate, oxygen saturation, and respiratory rate. With this device, you’ll get sleep and recovery scores daily on a scale up to 100. Biostrap has an interesting aspect that automatically detects, tracks, and analyzes repetitive exercises.

On the other hand, Whoop has sensors that collect data on HRV, heart rate, ambient temperature, and electrodermal activity all day long. This is the main reason why most athletes prefer this wearable. It also has a high sampling rate that allows it to give statistics with great accuracy.

Heart Rate Monitoring

On Biostrap, the heart rate monitor functions through red photodiode LEDs, while on Whoop, it works through green ones. Both are effective at tracking HRV, but Biostrap can also track blood oxygen, thanks to the red photodiodes.

Sleep Tracking

Biostrap doesn’t need any extra subscriptions or purchases to perform sleep analysis. However, if you want improved biometric data collection that includes snoring detection, there is a subscription for the service. This device has adequate sleep-tracking functionality that gives your overall sleep score.

Conversely, the Whoop provides insights on the number of times you’ve woken up in the night, how long you spent in each sleep cycle, your resting rate, and analyzes your sleep performance.

Biostrap battery should be charged daily since it won’t last more than two days. Biostrap usually sends a notification on the mobile app when the battery level is below 20%. The Whoop battery can last for five days. The best thing about Whoop is that you don’t need to take it off for charging. All you need is to slide the battery pack on without removing the strap from your wrist.

Additionally, Whoop comes with a battery indicator, which helps you to check the battery status. This feature is not available in Biostrap.

Biostrap and Whoop have a huge price difference. Biostrap band costs $175, which is enough to monitor recovery. But if you want additional accessories, you can get a Shoe pod at $250. There’s another option that goes for $320, which includes a heart rate chest strap.
