One of the perks of being a blogger is that I get to buy all of the cool tech gadgets in the name of science. I've always been a fan of fitness and sleep trackers so every time a new one comes to market, I usually grab it. The three big names in the space right now are the Whoop Strap, the Oura Ring and the Amazon Halo fitness band. 

I've used each of them extensively and this article will explain how they differ and which might be best for you.

Design and Comfort

The Oura, Whoop or Halo all look nice. It comes down to personal preference. 

The Oura Ring is a bit larger than a traditional ring and if you already have a ring or two you wear, you might start to look a little loud, but hey, maybe that's your look! You can also get the ring in different colors.

The only downside to the Whoop and Halo bands is that if you're like me and wear a smart watch, having the bands as well can look a little bit dorky. On their own, they look fine.


The Oura Ring is the only one of the three that doesn't have recurring costs. However, it is far more expensive upfront, starting at $299.

Whoop is the most expensive, relatively speaking, at $30/month, but that includes the cost of your band. 

The Amazon Halo membership is only $3.99/month and the device costs an easy $99 and comes with 6 free months of community access.


The Whoop community is by far the most engaged one I've been a part of.  Whoop's ability to create groups that show your daily scores with others add an awesome level of accountability and comradery that I believe dramatically increase the chances of you really pushing yourself. 

Oura has no community involvement and the Halo community is still growing. 

App Interface

Whoop, Halo and Oura in order of best interface to worst. 

They are all great but whoop is probably my favorite. 

Battery Life and Charging

Each charges extremely quickly. 60-90 minutes gives you a full charge for all three devices. 

The Amazon Halo is a power guzzler though if you run the tone analysis. You can set the timeline for when you run it to minimize its impact on battery life, but it will still turn the life of a charge from about 5-7 days to 1-2 days. 

The Whoop is the winner in terms of how you charge it. It's the only one of the 3 devices that you never actually have to take off thanks to the slide on battery charger. 

Also, all are completely waterproof and can be worn in any scenario.

Tracking Accuracy

I didn't notice any serious discrepancies in tracking accuracy across any of the devices. 

None of them were perfect though. Many times I'd check my sleep analysis and notice that it logged me as asleep long before I actually was or didn't actually track a waking time in the middle of the night. 

The Winner...

I'm sticking with the Amazon Halo for now. The body composition analysis and the tone tracking sold me completely. 

Wait!!! What About the Apple Watch?!?!

Sad Apple Watch

I didn't include the Apple Watch or any other smartwatch in this article because I feel like those are a separate product type. I still wear my Apple Watch in addition to whatever fitness band or ring I'm wearing at the time.
