A lot has been written about the value of the data collected by fitness and health tech - not least by Stuff ourselves - but whatever the insurance companies have planned for our future premiums, there’s no escaping the benefit of cold, hard statistics right now.
The good news is that data remained consistent and trustworthy throughout our testing – although natural fluctuations always occur when measuring body fat levels, as time of day, amount of water drunk and even how clean your feet are will all have an impact.
But which to buy? If money is tight and you’re only interested in weight then the Wahoo Balance will do just fine, but given there are so many more factors to fitness than pounds and ounces, it's worth spending more. The Tanita RD-901 is based on a professional machine and piles on the stats - useful, but with a less-than-perfect app, it could be daunting to the uninitiated. It's a similar story with the Garmin Index Smart Scales, which could be overwhelming to the non-Garmin fan. Elsewhere, the Under Armour UA scales don't quite live up to their app, while the QardioBase is more fun to look at than it is to use.
That leaves Nokia and the Fitbit. All combine a slick app with stylish looks and accurate data; all are intuitive to use and provide motivation far beyond the statistics.
Although the Nokia Body+ sadly lost heart-rate monitoring in the takeover from Withings (you can get this feature on the £150 Body Cardio), we'd say it just about wins this race, particularly as it's now easily in the sub-£100 bracket.
At this point, it's probably also worth holding off on the original Aria and waiting for the minor upgrades of the Aria 2 later in 2017.
Either way, it's also worth bearing in mind that neither the Nokia or Fitbit will exactly be cheap if you go the whole way (as you should) by investing in a fitness tracker too.
Still, if there's one thing worth spending some money on, it's surely your health.
