It's bigger and brighter, the new Xiaomi Smart Band 7

Xiaomi (Mi) have refreshed their fitness tracker the Xiaomi SmartBand 7. It comes in China and Global versions, the only real difference is that the Chinese version supports NFC payments (through Alipay). If you're lucky Alipay may accept your credit card as a payment type and then you can use it through the band. Both versions support multiple languages.

The 326 ppi AMOLED screen has been increased to 1.62 inches and is now much brighter (it can be distractingly bright), which is a 25% increase over the Band 6 display. The included USB cable has a magnetic connector on the end which aligns the connector with the band and holds it in place to charge.

Battery life is stated at 15 days, but that will be greatly reduced if various functions are turned on, such as some continuous readings.

Band 7 next to Apple Watch

There are a variety of straps that can be purchased apart form the standard black.

Watch faces are download to the watch (over 100 of them) via the Mi Fit app (now rebranded as the Zepp Life app). Some of them maybe quite Chinese in personality and seem quite odd to a western market.

The band has the following "health" functions: -

• SpO2 Monitoring
• Breathing Training
• Heart Rate Monitoring
• Sleep Monitoring
• Pressure Monitoring
• Female Health

SpO2 (blood oxygen content) and heart rate monitoring are continuous as is sleep monitoring (i.e. no need to tell the band you're going to sleep).

Band 7 supports 120 sports modes, some of which it will try and switch into automatically and it can be used for swimming down to 50m (but not diving). While training VO2 is estimated and time to recovery as well as aerobic and anaerobic exercise times.  Standard sports are directly accessed while others via the All Workouts.

What the band can actually measure during say a board game is questionable to say the least. Other sports modes to seem to work and it will pick-up walking and running without having to actually switch to that mode. 

Tracking is reasonable and compares to other much more expensive devices.

Nicely Xiaomi have now added a lot of products to their international store, including the Smart Band 7 which retails for £54.99 in the UK version (mi.com detects your location and uses that to deliver a local store). Straps costs £9.99 (they do break and the button on the clasp can break too).

It is also possible to go to your friendly Chinese site and buy it considerably cheaper (though pricing has changed recently and shipping charges can be more expensive and there will be VAT/Tax added at the point of sale).

Amazfit helping you build your Cor fitness

Amazfit are a relatively unknown brand in the UK, but they're big in China and are actually reasonably well known as as they make the Xiaomi Bands and it's possible to use Amazfit products with the Mi Fit app (which integrates into Apple Health - while the Amazfit branded app is standalone, though may offer some increased functionality with their products).

The Cor is the next generation on from the Arc which has a monochrome OLED display while the Cor is now colour. It has the usual complement of measurements, steps, sleep tracking, calories (made up as it's not tracking anything you eat etc) and pulse rate via n optical sensor under the body of the unit.

It's also possible to get notification from various apps and these can be enabled and disabled in the Mi Fit app.

Though the display is colour, it doesn't really add much to the previous and unless a preset display is chosen, some displays can affect battery life (as they get updated more often).

Step counting, heart rate and sleep tracking are comparable with the Fitbit AltaHR (wouldn't surprise if the actual electronics internally were the same or very similar), where Amazfit does excel is in price, the Cor can be had for around $40 from your favourite Chinese site. It's also waterproof to 5ATM so can be used for swimming and snorkelling and other water sports without fear of damaging it.

Amazfit are definitely a brand to watch in the fitness tracking department and they're constantly coming out with new products.

Recommended in terms of price and functionality, though the Mi Fit app doesn't yet compete with say Fitbit's, also battery life is claimed at 20 days and though it might not actually quite reach that, it will definitely last a week or 2 on a single 2.5hr charge.

Nokia puts the pressure on (your arm)

Nokia Health (as was Withings) has a blood pressure cuff - the BPM, though there's a newer version out now, the BPM+.

The BPM is quite bulky (the newer BPM+ looks quite a bit smaller in the cuff design) with a metal cylinder which has a power switch on the top and this connects to the white (quite stiff) cuff which you uncurl and wrap around your arm. It takes 4 AAA batteries

The cylinder is placed forward and it's recommended that you sit upright with your upper arm by your side and forearm at right angles forward (say resting on a desk).

Initially you have to go into the Nokia Heath app and add it as a device (there's a choice of the BPM and the BPM+), then in future when the cuff is turned on, the app will automatically open and offer to take a reading.

There are two modes when taking a reading, the first will just take a single reading while the second mode takes 3 readings (over 3 minutes). Both your systolic and diastolic readings are stored as well as your blood pressure.

The app can then display a record of the readings over time, to show how progress is being made (for example).

This could be especially useful if you have a medical condition (and results can also be emailed to your doctor).

The BPM costs £89.95 and the BPM+ £109.95 (though they function identically, they BPM+ uses a softer smaller cuff which means it can be put in a bag or similar and taken with you much more easily than the original BPM).

Xiaomi Huami AMAZFIT A1603 Smartband

Xiaomi make lots of stuff, but they also work with partners and specifically Huami who make wearables (under the AMAZFIT brand). In the US it's known as the Amazfit ARC.

Though the functionality is almost identical to the Xiaomi Band 2, it looks much nicer and the silicon strap has a 'hatch' effect on it which is very comfortable to wear. The actual unit is permanently attached to the strap and has a soft 'brushed' metal feel. Underneath there's an optical heart rate sensor and charging pins and the top is a UV coated scratch resistant OLED display.

Like most trackers it measures steps but also sleep (you obviously have to wear it at night), distance and active calories. The battery life is VERY good (Huami claim 20 days). It can also display notifications from your phone (currently iOS and Android are supported).

As a bonus it's also water proof and can be used when swimming, though it doesn't track swimming.

There's a USB charging cable that is magnetically polarised so it 'snaps' on to the charging pins on the bottom of the unit, this also stops you getting it the wrong way around.

There is an Amazfit app available and through it's pretty basic, it does support all the devices features and notifications, alarms etc can be set through it. However, it the ARC also works with the Xiaomi Mi Fit app, which has a lot more features and links with Apple Health and Android Fit on the relevant platforms. The Mi Fit app also seems to have a few more advanced features like being able to track heart rate when sleeping which give more accurate results (though reduces battery life).

It's definitely a cut above the Mi Band2 in terms of looks and comfort and on a par with traditional fitness trackers from established US companies, though at a very competitive price. However, the apps of more expensive western vendors are generally quite a bit better with more functionality.

The list price is $99 from the US Amazfit site, but various Asian sites have it available for around £30 including shipping.

Fitbit Alta HR - a pretty little fitness tracker

Fitbit are the leading manufacturer of fitness trackers (and foraging into the smart watch market with the purchase of Pebble assets last year). The Alta was released a while back and it was the prettiest of Fitbit's offerings. Now comes the Alta HR which is the name suggests, supports heart rate monitoring. Fitbit have managed to squeeze the LED system into the base of the unit (next to the skin) and still keep the same size as the original Alta.

There are various modes and the Alta HR can be set to record heart rate automatically or manually and to background sync etc. The different options will affect battery life, which is about 7 days on a full charge.

The Alta HR will track steps (and a run if you're inclined that way), distance travelled (but it's calculated as there's no GPS), calories and sleep (if you wear it to bed). If you do wear it to bed it will also calculate your resting heart rate as well as show your type of sleep (light, deep, REM and awake).

Though splash proof, it's not waterproof so no swimming or showering. When you remove the unit it should stop trying to read your heart rate, but sometimes it seems to continue to try to read it (the LEDs flicker) for quite some time.

The smarts is in the Fitbit companion app (Apple Health compatible on iOS) and that where most of the information is displayed.

There are a variety of standard bands that can be bought in different colours. They're made of a fairly chunky silicon that 'feels' pretty solid and use a standard pin/hole clasp to close so can easily be adjusted for size.

Fitbit are now selling premium leather bands and even metal bands which turn the Alta HR into bracelet, though they're pretty expensive and as they're solid, heart rate tracking may not work (as the unit may not be snug on your skin).

Fitbit make other trackers that are more functional, but the Alta HR is definitely the prettiest, but it's reasonably expensive at £129 or more for the premium versions. It's a lot compared to something like the Mi Band2 which can be had for about £16 (it's not as pretty) for almost identical functionality and the battery life on the Mi is over a month.

Beddit - tracking your sleep

Beddit is a device that has a little computing/Bluetooth module and a ultra-thin film sensor that's placed on the mattress that measures your sleep. The strip should be placed on the bed, approximately where your chest is.

Older versions of the device used a Bluetooth 2.0 module which meant the accompanying app (iOS and Android) took forever to connect, while newer versions have a Bluetooth 4 (SMART) module and as soon as the app is opened it connects almost immediately.

The app then tracks sleep quality, respiration and heart rate. It shows how many times you got out of bed, when you went to bed and when you got up. Unfortunately currently you need to start the app to do this which means if you forget, say because you're drunk - when you'd really like to know how you slept, it won't measure anything.

If you do remember to pen the app, then you get a nice display of min/max heart rate and averaged breaths per minute and then a visual graph of what kind of sleep you were in.

The next version of the app should automatically connect when near the Beddit sensor and then know when you go to bed and automatically track your sleep. It may also have a live display showing breathing and/or heart rate.

If you have problems sleeping, this won't cure them, but will show you your sleep patterns and maybe help you improve them.

If you're a Misfit user, Beddit also works with the Misfit app (so will use the Beddit to track your sleep rather than the Misfit Shine/etc).

Prices vary widely on-line, but it can be had for as little as £61.
