BKC × ZekNeo Smart Bracelet with 24/7 Activity & Sleep Tracking, Heart Rate, Blood Oxygen, HRV & Stress Monitor, GPS Modes(No Subscription)

About a week in, mainly using it for sleep, all day activity, and heart rate trends. I used Pixel Watch mainly for sleep and heart rate, as a reference.

What works: it's light enough that I genuinely forget it's on overnight, more than I can say for my Pixel Watch, which always felt awkward to sleep in. Sleep duration and heart rate matched the Watch closely across the week, close enough that I trust the trends. The AI summary is a nice touch, though I'd love charts in a future version, not just text.

Battery: 80% after 1 week use. (I will come back to update)

What doesn't: the app is little bit cluttered overwhelming at first (if you not familiar with Android permissions). A few labels are ambiguous: there's a "Disconnect" button that reads like a status indicator until you tap it and find it's actually an action. I understand some of that is Android's own UI conventions, I expect the UI get more polished further down the road. A tiered easy/intermediate/advanced UI would help. Waiting to see new update :)

Bottom line: solid 4.5 stars. Worth it if you want a sleep friendly screenless tracker and can stomach a busy app on day one.

I Never regret to choose this. I love how comfortable to wear everyday. Very light. 4days now since I started using it and only 12% of the battery is used. Just download the apps and you will monitor everything there.

I’ve been using this fitness tracker for a bit now, and it’s been a great addition to my routine. Setup was quick, and it paired with my phone easily.

The health tracking is impressive for the price—heart rate, sleep, and blood oxygen all provide useful insights for everyday fitness goals. Battery life is a standout, lasting for a really long time!

It’s also lightweight and comfortable enough to wear all day and even while sleeping. Overall, it’s a reliable, feature-packed tracker that offers excellent value without breaking the bank.

So far I love this fitness tracker. I was mainly interested in my sleep and stress level and this is pretty cool to see the data. I was curious how it compared to my apple watch as far as steps, etc and it's surprisingly similar to my watch. The app is super easy to use and customize and I've had no negative issues with it at all. I read some reviews that said the app was problematic but I've had no problems with it. I love how long this stays charged, much easier to use for health tracking than my watch. I keep it on for everything except my shower. I love the choice of bands that came with it, there are three to choose from and they are highly adjustable. I have a fairly small wrist and it cinches up small enough without being bulky. There are a variety of band colors to choose from so this could be worn even with dressy clothes and be minimally noticed if you get a neutrally light colored band. I highly recommend this fitness tracker. It may not be 'medically accurate' but it's a good option to see basic results and have somewhat of a baseline. I've included some of the screen shots of the app options and features, each one of those lines takes you to a specific screen for that feature. All data is displayed in one easy to read page. One of the neatest features is the ability to generate a 'health score report' that is AI generated and extremely detailed. I wish I could include a photo of it but it's personal data so I won't share; just know that it is one of the best features this device has. Again, not a substitute for any medical information or diagnosis; but still very valuable information that I have found to be very accurate for me.

This tracker works great, is lightweight and comfortable enough to wear continuously.

Compared to my Fitbit inspire 3 it is just as accurate and seems to last at least twice as long. However unlike my Fitbit it does not convert activity to steps (software issue I would imagine.) It does allow me to more closely monitor my SpO2 which is nice given I have had lungs clots in the past. It still does not allow me to use the BPM monitor in other apps though (looking at you Supernatural) which I believe could be a software enhancement.

I like the fact that it allows for tactile notifications which are discreet and strong enough to get my attention.

It is well packaged and the instructions on how to set it up are easy to understand. It does come with two band options (one silicone and one mesh fabric), The charger is magnetic but fairly light so it twists easily depending on how the cord was wrapped. There are three magnets in a triangular pattern which make alignment for charging fairly simple.

The software is Qwatch. This seems to be a fairly generic smart band software. The setup was straight forward and pretty simple, but seems fairly barebones and the AI component requires you to login and send your data off to who knows where, I'm not OK with that. However the rest of the measurements seem to work fine without a login. A decent open source firmware would be nice but as of today I could not find one.

All in all a good band at a good price held back by software I feel
