Atlas calls itself 'the first fitness tracker' which isn't strictly true. But its maker believes that it deserves this moniker as it identifies what workout you are doing, evaluates your form and will even count your reps for you. It's like having a personal trainer without the massive inferiority complex that inevitably goes along with this. Oh, and it will also measure heart rate as well as working with many a fitness app that's out there too. And, looks wise, it definitely gets our vote.
