Mio Fuse – a heart rate mon­i­tor that is enough for every­one. A good option for those who have not yet acquired some­thing sim­i­lar.

What is it and why is it necessary


Mio cre­at­ed a uni­ver­sal device that will suit both ordi­nary peo­ple and those who dili­gent­ly mon­i­tor their phys­i­cal form.

  • It is con­ve­nient to use while jog­ging and cycling. Espe­cial­ly if you don’t like to ban­dage your­self with chest straps.
  • The track­er will be use­ful for train­ing in the gym for those who need to track their heart rate for bet­ter results.
  • It will come in handy even if you are not active­ly involved in sports, but just want to keep fit. To do this, the bracelet tracks dai­ly phys­i­cal activ­i­ty.

To be hon­est, you won’t be able to find any­thing bet­ter or more ver­sa­tile than the Mio Fuse. He can do almost every­thing that is expect­ed from activ­i­ty track­ers, with the excep­tion of account­ing for sleep phas­es.

What’s in the box

The deliv­ery set does not strike the imag­i­na­tion, and in prin­ci­ple, it should not. The box in which the fit­ness bracelet is sup­plied con­tains the track­er itself, a mag­net­ic charg­er dock with an inte­grat­ed USB cable, and book­lets with sim­ple instruc­tions and war­ran­ty ser­vice con­di­tions.


Although the man­u­fac­tur­er offers devices in two col­ors, buy­ers will not have much choice. The point is that turquoise Mio Fuse Aqua only avail­able in small size and red Mio Fuse Crim­son — only in the big one. And although the true motives for such a deci­sion are unknown, it is log­i­cal to assume that, in this way, the man­u­fac­tur­er sep­a­rat­ed the male and female mod­els.

The device is made of softsoft touch” sil­i­cone and weighs less than 40 grams. Unfor­tu­nate­ly, a tac­tile­ly pleas­ant mate­r­i­al, like a mag­net, attracts dust par­ti­cles from the sur­round­ing air. There­fore, achiev­ing per­fect clean­li­ness of the gad­get will be a non-triv­ial task.


In the cen­ter, under a translu­cent coat­ing, there is a small LED screen, which, in addi­tion to dis­play­ing the col­lect­ed data, can serve as a clock.

Of course, the Fuse is a lit­tle on the big side com­pared to its com­peti­tors. How­ev­er, the styl­ish red and black bracelet looks just fine on the hand. Its design is con­cise, devoid of catchy details. Even in com­bi­na­tion with a shirt and a suit, the device looks quite appro­pri­ate. In my opin­ion, Mio offers one of the most beau­ti­ful activ­i­ty track­ers on the mar­ket.

The gad­get is con­trolled by three touch but­tons: two locat­ed on the sides of the screen, and one cen­tral. The side but­tons are respon­si­ble for nav­i­gat­ing through the track­er’s menu items, and the cen­tral one is used to switch oper­at­ing modes.


It is worth not­ing that Mio Fuse is two devices in one. The first is a reg­u­lar fit­ness track­er that will count your steps, calo­ries burned, progress towards your goals. The sec­ond is an advanced heart rate mon­i­tor from Mio, which is in no way infe­ri­or to the updat­ed Mio Alpha.

By long press­ing the cen­tral but­ton, the track­er is switched to the heart rate mon­i­tor mode and starts mea­sur­ing the pulse. After that, it will be pos­si­ble to start record­ing a work­out, which can be start­ed / paused by briefly press­ing the cen­tral touch but­ton. In train­ing mode, the track­er can dis­play its dura­tion, speed, dis­tance trav­eled, calo­ries burned and, of course, the cur­rent heart rate. Also in train­ing mode, a sep­a­rate col­ored LED will show which zone your heart rate is in. This will be use­ful for those who, depend­ing on the type of activ­i­ty, must main­tain the desired heart rate. Also, when mov­ing from one heart rate zone to anoth­er, the heart rate mon­i­tor will give a sig­nal with a built-in vibra­tion motor.


You can save your work­out data and switch back to the activ­i­ty track­er mode in the same way — by long press­ing the cen­ter but­ton.

The bat­tery charge should last for a week with dai­ly work­outs last­ing about an hour. In the con­tin­u­ous heart rate record­ing mode, the bat­tery will last about 10 hours.


All data that Mio Fuse reg­is­ters, whether it’s saved work­outs or just progress towards achiev­ing dai­ly goals, is auto­mat­i­cal­ly syn­chro­nized with the pro­pri­etary Mio GO appli­ca­tion via the built-in Blue­tooth 4.0 mod­ule.

By the way, the mem­o­ry in Mio Fuse is enough to store up to 14 days of dai­ly activ­i­ty records and up to 30 hours of train­ing. And you don’t have to wor­ry about the device run­ning out of mem­o­ry sud­den­ly. When free space is left for 2 hours of record­ing, the track­er will report a lack of mem­o­ry with the mes­sage “LOW MEM“. Dur­ing the remain­ing time, it is bet­ter to find an oppor­tu­ni­ty to syn­chro­nize data from the bracelet, oth­er­wise the screen will dis­play “NO MEM“, and data record­ing will stop.

When you first launch the Mio GO app, you will be asked to reg­is­ter, fill in a brief infor­ma­tion about your­self, and auto­mat­i­cal­ly con­nect the track­er.

How does it work


You can ini­ti­ate a work­out record­ing not only from the bracelet, but also from the native Mio GO appli­ca­tion. Despite the fact that it can record 8 dif­fer­ent types of activ­i­ty, the data will still end up in Health.app as “Walk­ing or jog­ging”.

In gen­er­al, heart rate data can be used by any sports appli­ca­tion that sup­ports the con­nec­tion of exter­nal acces­sories. There­fore, using the same Run­K­eep­er or sports track­erseems more rea­son­able to me. They are able to issue voice noti­fi­ca­tions dur­ing train­ing, have advanced tools for assess­ing your achieve­ments and good social inte­gra­tion.

In Mio Fuse, the accu­ra­cy of heart rate mea­sure­ments turned out to be expect­ed at a height. More­over, I neglect­ed the man­u­fac­tur­er’s rec­om­men­da­tions and put on the bracelet both on the inside and on the out­side of the wrist, and with and with­out an indent of 8 cm from the bone on the wrist. The pulse mea­sure­ments were always accu­rate.

Among oth­er fea­tures of the fit­ness track­er, it is worth not­ing that it sup­ports the ANT + pro­to­col. This means that the Mio Fuse will be able to send data to an impres­sive list of GPS watch­es or bike com­put­ers. Yes, and water resis­tance will not be super­flu­ous. The man­u­fac­tur­er does not rec­om­mend swim­ming with the track­er in the pool, but it is quite pos­si­ble to use it in the rain.

In the process of use, some incon­ve­niences asso­ci­at­ed with the form fac­tor of the device showed them­selves. So, Fuse looks bet­ter when it is worn on the out­side of the wrist, but it is more con­ve­nient to use it when put on the inside.

In the first case, in order to read the data, the hand must be twist­ed at an unnat­ur­al angle.


And in the sec­ond, the clasp of the bracelet will be on the out­er, vis­i­ble side of the wrist, which looks a bit rus­tic.


In addi­tion, I found that some­times the bracelet does not respond to key press­es. It turned out that the accelerom­e­ter blocks the but­tons when the bracelet is in a hor­i­zon­tal posi­tion, which cor­re­sponds to the ver­ti­cal posi­tion of the hand. Appar­ent­ly, so, the man­u­fac­tur­er decid­ed to exclude erro­neous but­ton press­es while walk­ing or dur­ing class­es. The lock does not bring dis­com­fort in han­dling the device, but it requires, at a min­i­mum, get­ting used to.

Among its weak points, I can only attribute the need to com­pro­mise in the choice of wear­ing method and the soil­ing of the mate­r­i­al from which the bracelet is made.
