I love Bionny! A lot of people around me are swapping their Apple Watch for a Whoop, but I’m sticking with Bionny. I appreciate the updates that keep improving the product! The information it provides is really useful, and the band is so much more comfortable, less expensive, and most importantly there’s no subscription. I recommend it.

I recently bought a second Bionny 4.0 for my son because I have been so happy with my own. It provides all the health metrics I need without requiring an ongoing subscription, which is a huge plus.

The quality is good and it's very simple to install and use. The battery is impressive, it lasts a long time. Very satisfied so far.

Its been 2 weeks of using Bionny and I have to say I'm really pleasantly surprised about the amount and quality of data provided.

Battery is very good,it lasts many weeks. I also like to use the app, it’s easy and simple.

Really good, and after three days of use the battery is still at 100%.

Nice, comfortable and soft to the touch, with a very good strap. The only downside was that the shipping took a little longer than expected.

Works really good, the BP function is very close to the cuff. Had it for a week now and it works way better than a band which is twice if not 3 times as expensive, and to get more data you have to subscribe. With the Bionny 4.0 its free, no subscription.

This is the fourth band I have purchased, and I must tell you it is by far the most professional I have seen and I’m extremely happy with its performance Unfortunately, more people should take the time to investigate this product. They would understand it is fantastic. It’s accurate and extremely reliable. From an engineering standpoint, I think it is a fantastic device and I thank you for making it and thank you for selling it to me. It is truly a jewel in my life. Best regards

I was a bit sceptical at first. But this has blown me away for the price of it. It is so comfortable to wear I do not even register it is actually on my wrist. If anyone is thinking about purchasing one do not hesitate. It is 10 out of 10 from me.

Well my new black nylon strap looks very professional and my bosses are absolutely spellbound by the performance of my lifestyle monitor it’s keeping me updated daily about my health it’s a game changer and no monthly subscription to worry about.10/10

Angela was really helpful with a recent query, responded very quickly and told me exactly what actions were needed. I am very pleased with my band so far and would recommend to friends and family.

Accurate readings, long-lasting battery (easily around 30 days), a clear app, and plenty of settings.

Bionny track did exactly as advertised. It monitored all my biometrics PLUS gave accurate blood pressure results. Could not ask for more, plus you also have different colour bands if needed.

We've both been wearing the Bionny 4.0 every day. It's so comfortable we forget it's on, and the health insights have been incredibly useful.

Fantastic. Works well. Holds battery life well. I’m really happy with all the data and it’s comfortable on my wrist not suffocating and annoying and weirdly sticky and sweaty like most fitness watches.

Does exactly what says on the tin; offers the same as other brands but without the price ticket and subscription. I totally disagree with the bad reviews out there claiming it's 'merely a rebranded Chinese version'.... aren't they all? even the big brands are Chinese made and merely re-branded. those who say they aren't are either selling a brand or hypnotised by a brand. Bionny Works!

I’ve been using it for about a week and everything seems good so far. I bought three for the family.

Simple design, comfortable to wear, clear app, overall very good and no subscription. Perfect!

The band is very comfortable and so light that you barely notice it. The battery also lasts a long time. Of course, the readings shouldn’t be considered medical measurements, but they’re still helpful in everyday life for getting to know your body a little better.

I am very pleased with it. It is noninvasive meaning the wearer can check measurements as often or seldom as desired. I have tried other types of watches ye I wasn’t as satisfied as I am now. Thank you for producing something so good!

Heart rate is spot on during workouts. Sleep detection occasionally logs reading-in-bed as light sleep, but the daily and weekly trends are reliable.
