Has so much potential. Wish they’d update the app, September 24, 2014

Vine Customer Review of Free Product (What’s this?)
I like it, but it’s not everything it should be.

First off, the product picture shows the Mio App with a graph of heart rate use. Problem is, you won’t find that graph in the app.

Other issues.

It records your heart rate only when you hit record on the app. It will display your heart beat data, but it won’t record until you hit record.

The recorded results aren’t much: Distance, Duration, Calories burned, average heart rate, max heart rate, average speed, max speed, and total gain (total gain seems way off).

It would be much more helpful to see the results in graph format so you can see how many times you hit the target zone!

Now, there is an "Outdoor" and an "Indoor" section in the app. The "Indoor" section might have access to graphs when you’re working out inside. Problem is that the section freezes up when I try to access it on my phone. I’ve tried many times. Finally, I was able to get in. It asks to download videos to your phone, so be ready for it to take up 479 MB of storage for a single video. That’s huge. There’s no reason for the videos to be that big.

The app could also explain a little more why you want the videos which become more apparent when you use the indoor feature (if you can actually get it to work without freezing up).

Connections should be automatic, but it seems like I have to click the Mio Global link for it to connect.

About the band…
The band is nice. It’s a good fit and has many options for different wrist sizes. It doesn’t get hot and neither has it made my phone get hot because of the wireless connection eating up phone power..

However, that LED light could be muted. It blinks so bright, it’s a distraction. They should have covered it better.

The texture of the band, the fit is nice, it’s just that LED that’s so annoying.

So overall, it feels great to wear. The app needs improvement (better tracking, stability), and that LED light on the band is more intense than it it needs to be.

Other than that, yes, it is good to have and useful. Comfort is important when using a heart rate monitor, and this one is comfortable.

Is it compatible with the Apple Health app? Not as of yet, but hopefully in the future.

Fabulous concept and design; hindered by a few performance issues, September 22, 2014
Vine Customer Review of Free Product (What’s this?)
I’m no fan of ‘wearables’, especially during exercise, so the Mio Link had to prove that it could meet two performance points:

– invisibility (I need to forget I’m wearing it except when I need the info)
– accuracy (an in-exercise heart-rate monitor is all about real-time info, so it needs to be quick and accurate)


The Mio Link is really well-done in design. It’s functionally weightless and low-profile. Made of rubber, it’s form-fitting, and the fastening mechanism is soft plastic, so it doesn’t irritate or chafe and adjusts easily. In other words, it is indeed functionally invisible.

The electronic component is actually just a small unit that sits inside the rubber band; it comes out easily when the band is off, so it can be transferred to bands of other colors/sizes. when worn, though, it’s perfectly secure underneath the band.

Operation comes via a single button that sits flush, and readouts come via a single LED light that illuminates in various rhythms and colors. The readout system is intuitive and easy to learn. In fact, my only complaint with the design is that the readout could stand to be a little MORE visible during exercise where the arms are moving a lot… vigorous running, pretty much. On a bike, though, the light should be visible at all times, and it’s bright enough to be seen even via peripheral vision in a moderately-lit space or environment.

To summarize, it’s fantastically well-designed- attractive and sharp and easy to use.


The Mio Link has two modes: ranged and target-zone. In ranged mode, it breaks the heart-rate spectrum into six user-definable ranges, and gives the user a colored pulse to indicate which zone they’re in. In target-zone mode, the user defines a target range and is told when he/she is in-target. These parameters are set via the iPhone app, which is VERY well laid-out and intuitive.

I used my Mio Link in the multi-range mode during a 45-minute stationary bike ride at 85% heart rate, comparing its performance to the bike’s on-board heart-rate monitor. It consistently registered 3-5 BPM slower than the bike, but that’s a perfectly acceptable error margin.

My issue with its performance lies in the real-time aspect. Specifically, there were times when the LED color didn’t match the readout on my iPhone… and the inconsistency didn’t seem to follow any pattern (i.e., the band always being ahead of the software); rather, they just weren’t perfectly synced, and were sometimes off-sync by 20 or 30 seconds. This isn’t a HUGE problem, but it IS a problem. My cardio sessions are designed to keep me in a particular heart-rate range, so I need up-to-the-minute data that’s accurate. Especially for runners, who don’t have access to a second monitor or to the iPhone app, the info needs to be on-point. As I said, it isn’t terrible, but it can use some calibration.

The other problem I had concerned the target-rate mode… specifically, I have no idea how to activate it. The literature doesn’t mention it, and I only know about it because the iPhone app has a section for setting the range, though no option to switch to it.

The reason I’m not lowering my rating for the Mio Link more is because these two issues are both functions of the software, and my suspicion is that these are out-of-the-gate issues that will be resolved in subsequent software updates.

In terms of design and potential, the Mio Link is awesome. I’ve never used a wearable heart-rate monitor before, so I have no point of comparison, but I find this to be easy to use, intuitive, attractive, and comfortable. Once the updates come along, it’s only going to be better; when it does, it has full potential to be a five-star product.

It grips on extremely nicely too and just sits there being easily forgotten, September 18, 2014

Vine Customer Review of Free Product (What’s this?)
The level of comfort this thing offers was a big surprise to me. The band is some kind of plasticy material, but it’s texture and the fact that it’s full of holes makes it very flexible and much more breathable than it normally is having a band on my wrist. It grips on extremely nicely too and just sits there being easily forgotten.

I also don’t know what’s up with the picture, but they recommend that you wear the band an inch up fron the wrist bone. The photos of the product show it worn down lower than the package says you should. For me this is a good thing, because having things squeeze down on my wrist too much bugs me. Moving it up an inch or two feels much better (and I’m wearing it right now and messing around at the computer obviously, and I’m spared having to feel it press into my wrist every time I move my hand too close to the desk).

So far the actual heart rate tracking looks good, though I haven’t put that through terribly extensive testing yet. Getting it paired to a smart phone to share data with apps was also pretty quick and easy.

It does have a custom charger, which is something that I dislike from many devices (since it can mean big expenses if you lose the charger or a pet chews it or something), but I can forgive it on something like this where there’s a very legitimate concern about leaving a micro-usb hole (or whatever) that sweat could flow into and ruin the device. It IS for wearing when you’ll be getting sweaty, after all.

I need to try it in a wider range of conditions to be sure (the instructions say something about starting it before going outside when it’s cold out. I’m not sure if that means it can be quirky in the cold otherwise or what exactly) but my early impression is strongly positive. It stays in place, seems to read very accurately, and it’s been very easy thus far to forget it’s even there. Also, I have very sensitive skin and there is (thus far) no sign at all that there’s anything about the band that’s irritating it (I’ve left it on for probably the last 12 hours, just to check on that detail).
