The first tests of our Bionny 4.0 bracelets are very satisfying. I was able to evaluate mine during an 18 km run to compare my cardiac metrics with my Garmin Fenix 6, and the results are very simila... See more

SCAM - they will never send you!!
Have purchased 2 bionny on 5th Sep 2026 and have been asked to give a review on Trustpilot about the purchase experience that certainly was easy.
Today, 21st Sep, the two bionny has not arrived and Bionny customers service has not given any updated about status or whether they will reimburse or sent them again.
For the time being they have just taken the money since 16 days and delivered NOTHING......SCAM!

Using no tracking transporters
Using no tracking transporters. Almost two weeks to arrive. Sports ativities never registered more than two or three minutes even if the duration is more than 2 or 3 hours

Great purchase
Great purchase! BIONNY 4.0 is lightweight, comfortable and very useful for tracking sleep, HRV, heart rate and daily activity. I especially like the Apple Health integration and the fact that there is no subscription. Great value for money!

I was struggling with my health and while I was researching lifestyle monitors I found Bionny 4.0.
It ticked all the boxes. Being subscription free for life, it was a no brainer.

“It’s an excellent solution compared to others on the market, with no monthly or annual fees for data collection, and so far it has proven to be a reliable partner in monitoring physiological needs — cardiac, rest, and more — as well as a solid companion for overall body management.”

Comparison
Everyone has their own experiences. Delivery was on time. So I get to match with my Whoop for comparison. It's not as big as the Whoop so I wore them on the same wrist. Comparisons after day 1 almost identical. So far so good. Will a more robust strap be coming? Hope so.
It's light. Straps are quite comfortable and it's affordable. Let's see what the next few days hold. Looking forward to the comparison test.

Poor strap which keeps unclipping
Seems ok, I had the strap on wrong way round. . Metrics no idea of accurate but they should be ok after a time of wearing. 1 major issue the strap just keeps coming undone. Really annoying.
