A smart scale is a great first step if you're new to tracking your health. It takes a ritual you're used to, connects it to your phone then adds as many or as few extra metrics as you want to track.
Buying a smart scale from the likes of Withings or Fitbit could also be one of the best ways to keep track of your health goals. A whitepaper by Withings has shown that those who track their weight regularly are more likely to succeed in hitting their weight goal, and there's a plethora of devices on the market to help.
A top body analyser will track your weight, body fat and even heart rate, plotting your progress on your smartphone, so you can get a feel-good buzz about shedding the pounds.

However, buying a smart scale isn't just about the bit of plastic or glass you stand on. It's also about the ecosystem that tracks your weight and how useful the information can be. Read on for our round-up of the best out there.
Withings Body Cardio
Like the majority of smart scales, the Withings Body Cardio measures weight, BMI, body composition (fat, muscle, water and bone mass) and standing heart rate, sending each to the Withings Health Mate app pretty much immediately.
However, the company's latest scale goes one further and adds Pulse Wave Velocity (PWV), which the company claims is a key indicator of hypertension. PWV is a measurement of heartbeat-generated vibrations and can sniff out stiff arteries or high blood pressure. If you're a health nut interested in this, just be warned that not every weigh-in captures this data. It can be a bit of a pain.
The heavy-ish Withings scale does indeed work on carpet as well as hard flooring, as claimed, something that would throw off its older Smart Body Analyzer.
Aside from great stats and accuracy, Withings Health Mate picked up the best connected health platform gong at the Wareable Tech Awards, for the way in which it tracks weight, heart health, fitness and sleep data. You can connect to the MyFitnessPal app to track food, set weight targets and you'll get badges for reaching new low weights plus add more than one user per household.
The Aria was launched back in 2012 and remains one of the most reliable and informative health gadgets, offering accurate stats about weight, BMI and fat percentages for up to eight registered users.
The scale is a good-looking wedge of glass available in black or white. The backlit display flashes a range of data including identification, weight, body fat percentage and lets you know when uploading over Wi-Fi is successful.
As a standalone set of scales the Withings offers more, but Fitbit owners will get more from adding the Aria to their health tech line-up, rather than opting into a whole new ecosystem.
The app (or dashboard software if you prefer) is easy to navigate and after a few weeks the weight/BMI graphs will start to make useful, rather than daunting reading. For a complete assessment of your eating and exercising habits there's also a food diary log, and to keep you motivated you can sign up to compete with friends and boast about triumphs (or not) via social media.
Polar's smart scale supports up to 10 individual profiles, and will keep a log of weight and body mass index (BMI) within the Polar Flow app. It works using Bluetooth Smart to link to a paired smartphone or Polar Loop band, which will show you progress against your weight goal. It's lacking some of the metrics you get with the Garmin and Withings and won't display body fat percentage or muscle mass data.
Under Armour HealthBox
Available primarily as part of the Under Armour Health Box, which comes with a fitness tracking band and heart rate monitor, the scale is a standard affair which isn't as comprehensive as its rivals. It tracks weight and body fat percentage and can recognise up to 8 different users. The data syncs into Under Armour's impressive app ecosystem and it can be tracked with MapMyFitness and MyFitnessPal as well as UA Record.

The iHealth Core measures more than just your weight, adding muscle, bone, water and into the mix with bioimpedence tech, as well as BMI and all the usual data. Supporting up to 10 users, it feeds into the growing iHealth ecosystem and records and tracks data within the ByVitals app. The company also builds glucose monitoring and blood pressure devices, making it a top competitor for Withings' excellent health monitoring devices.
Another Bluetooth 4.0 device, this time for iOS users only (iPhone 4s and above), but the Balance looks good and syncs quickly with the Wahoo Wellness app. It tracks weight and BMI, and has the option for 16 different profiles and weight goals and handily it stores up to 130 weights so you don't have to have your phone with every time you weigh in.
The Wellness app offers the usual collection of graphs and goal alerts, but handily it can also sync your weight data with the superb calorie counting, exercise logging MyFitnessPal range of apps. Wahoo isn't unique with this – Fitbit and Withings both offer the same data sharing – but for the price it is a great extra to have.
Garmin Index Smart Scale
The new Garmin Index scale is one of the most complete scales out there, with both Bluetooth and ANT+ connectivity built in, which means it can pair with your smartphone and fitness watches such as the Fenix 3. It measures weight, body mass index, body fat and muscle mass and have them added to the Garmin Connect platform, which is superb for runners and users of Garmin's sports watches. The Index scale will also support up to 16 different profiles.
