REVIEWS
"We decided to partner with Biostrap because we believe in the standard Biostrap sets with regards to accuracy. For HealthQb, it was a critical piece for us to have a scientifically valid wearable device when it comes to HRV in particular because of how sensitive of a metric that is. We have to make sure that it's measured accurately."
- Greg Elliott, Co-founder of HRVCourse.com & Co-Founder of HealthQb Technologies

"Biostrap's ability to remotely monitor my health from anywhere is a huge piece of the puzzle in giving us a chance at accomplishing what we believe may be endurance sports history."
- James "Iron Cowboy" Lawrence, Guinness World Record Holder, Author, and Speaker

"Biostrap has really just helped me see what components I can tweak in my lifestyle that really do make a major impact on my sleep status."

### 1/5 — App doesn't work, nonexistent support

*2025-03-27*

The app stopped syncing and storing data properly.

Also I emailed their support about the band itself over a month ago and still haven't gotten a reply.

### 1/5 — App issues

*2025-03-25*

All of a sudden the kairos stopped syncing with the app for iPhone and then I’ve been unable to sign in the app.

### 1/5 — Not good at all

*2023-10-14*

I am part of a UK trial of this product, and have checked what I am about to say with colleagues on the trial. This product is in my opinion, woeful. I sat writing at my desk for a few hours and it tracked about 20k steps! I read a book in bed, another few hundred steps. So I was losing confidence, and then here comes the big one….

The app gives you a sleep score. I wake up, open the app and it starts calculating. Let’s say the score is 95. A few hours later I check it again and the score is 100 and the app says I woke up 40 mins after I did, and had done all of the above! This is consistently happening, a colleague has told me they have given up manually re-calibrating it. 

So unlike Whoop or Apple Watch I have zero trust in the very unattractive biostrap (people say it looks like a tag someone gets on prison release) and what I have found to be misleading app in my opinion.

Pay a bit extra and go with Whoop…or work out how to read accurately Apple Watch or similar readings. Mine is now happily gathering dust in the drawer after a months use.
