Bionny Reviews 

quality product, design

We purchased two Bionny bracelets, and unfortunately the experience has been disappointing from start to finish.

The delivery took more than two weeks, and the package was handled by an unknown courier service that simply left it outside our property, making it easily accessible to anyone passing by.

After unpacking the bracelets, it quickly became apparent that one of them was malfunctioning and failed to transmit any data to the app. The second bracelet appeared to function better, but the accompanying app itself is very basic and provides limited useful insights. In addition, the translations throughout the app are poor, which further detracts from the overall user experience.

When I contacted Bionny customer support, I had to send several follow-up messages before receiving a response. Even then, the support provided was far from satisfactory. The company has refused to replace a defective bracelet and is unwilling to accept a return, citing vague and, in my view, legally questionable reasons.

Based on my experience with both the product and the customer service, I cannot recommend these health trackers and would strongly advise potential buyers to look elsewhere.

I ordered their tracker a couple of weeks ago. Got a wonderful and promising whats up message that everything from ordering to delivery is going to plan and I could track the order with delivering agent YODEL. It turned out that I cannot do so. On 'View my order' in what's app it states the item is on its way, and that has not changed for a week now. Several messages via WhatsApp remained unanswered . Communication in that way is shockingly inadequate. Therfore I cannot recommend buying from Bionny.
Update:
The tracker finally arrived today 2nd June. Therfore I have to revise my verdict to 3 stars . It still does not excuse the lack of communication by BIONNY. I also have not tested the functionality and accuracy it promised in there promotion. Therefore I will update my review on the product again in due course.

**Bionny 4.0 Health Bracelet - Do Not Buy. Waste of Money.**

⭐ 1/5 stars

After purchasing the Bionny 4.0 health bracelet for €99, I've had a frustrating experience that I need to warn others about.

**Technical Issues:**
The QwatchPro app (on iPhone) only syncs daily steps with Apple Health. Workout data – which is the whole point of a fitness tracker – is NOT exchanged. This severely limits its usefulness as a health tracking device. The app is essentially non-functional for serious fitness monitoring.

**Unreliable Customer Service:**
When I decided to return the product, I discovered why they can afford cheap pricing: their return policy is deliberately designed to prevent refunds.

- The return process is intentionally complicated with unrealistic conditions
- Despite multiple emails to customer support, they simply won't provide a return address
- They make promises in their responses, but nothing actually happens
- You're constantly strung along – no resolution, just silence

**The Bottom Line:**
Bionny operates as an unreliable organization with zero customer commitment. They take your money and make it nearly impossible to get it back, regardless of the product's failures.

**My Verdict:**
Do not waste your €99. The phrase "cheap is expensive" perfectly applies here. There are far better fitness trackers at similar price points from companies that actually stand behind their products and provide functioning apps.

I strongly advise against this purchase. You will regret it.

OK Guys, no matter what positive reviews written before and after... this is really cheap chinese piece of plastic worth nothing... you can count it as scam! For sure you'll find it at Temu for 30.00 USD or less - if your looking in such device - OK! Blood pressure readings are far from reality (always same reading, always in optimal range with is not the case)- as well as the heartrate... Steps? I don'nt know,... and I'm not a bot - I'm a real human! So be warned!

I had high hopes for Bionny, since they compared it to Whoop. It could work as a health gadget, but does not work in sports. The hr measurement is way to inaccurate (at least on my device) and in my opinion, you can’t get ecg readings out of it, even if that’s one argument on their homepage/advertising. Not worth to spend money on this, put a little more in, and you get a device that is reliable and more accurate with ecg readings.

Product Limitation: Proprietary Bluetooth Protocol Restricts Third-Party Compatibility

Dear Bionny Support Team,

I am writing to formally express my frustration regarding the fundamental incompatibility of the Bionny fitness tracker with major fitness ecosystems and devices. After purchasing your bracelet with the expectation of seamless integration into my existing training setup, I discovered that it cannot connect to either my Garmin sports watch or any mainstream indoor cycling platform such as Rouvy, Zwift, or TrainerRoad.

Upon investigation, I learned that your device uses a proprietary Bluetooth protocol that is incompatible with the industry-standard BLE (Bluetooth Low Energy) Heart Rate Service (GATT 0x180D) specification. This means that heart rate data collected by your bracelet is locked within your proprietary app ecosystem and cannot be exported or integrated with third-party applications—a significant limitation that was not clearly communicated at the point of sale.

This is a critical flaw in your product design. In 2026, fitness enthusiasts expect their devices to interoperate across multiple platforms. The fact that your bracelet's health data cannot be shared with my Garmin watch or used to power my indoor cycling workouts makes the device substantially less valuable than advertised.

My questions are:

1. Does the Bionny bracelet support the standard BLE Heart Rate Service protocol? If not, why not?
2. Are there any plans to implement industry-standard Bluetooth protocols to enable third-party integration?
3. Why was this limitation not clearly disclosed in the product description?

I would appreciate a transparent response regarding your product's technical limitations and your roadmap for improving cross-platform compatibility. Otherwise, I will be pursuing a return and recommending that potential customers consider competitors whose devices actually integrate with mainstream fitness ecosystems.

I look forward to your prompt reply.
