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.
