Our quick take
Fitbit Charge HR - 4.5 / 5
Simple design
Activity tracking plus caller ID
Great heart-rate monitoring
Basic sleep tracking
Fantastic Fitbit platform
To recap
The Charge HR is a fantastic activity tracker for those that use the gym as their main source of exercise, embracing it where its competitors penalise. It lacks GPS, water resistance should be better and the sleep tracking could be improved but it runs on a fantastic platform and it’s accuracy is brilliant from our experience. It’s not the best looking activity tracker out there, but it is one of the best.
