Although Fitbit has quite a number of devices on the market, its popular, and best-selling wearable is the Charge HR. Back in 2014 when it was revealed, it was one of the first to incorporate heart rate sensors, while still maintaining a small size. Fitbit just unveiled the successors to the Charge and Flex devices.

The Fitbit Charge 2 is much larger than the original model, in order to pack in a few new features. The Fitbit Charge 2 now has a built-in GPS, which will now track your location while cycling, running and walking. The GPS will let the device add tracking to your workout, and will allow for a more accurate reading. The Fitbit Charge 2 also has a new breathing feature called Relax, which will guide you through a 2 or 5-minute breathing activity. All-round the Fitbit Charge 2 has seen an improvement, from connectivity, to better health readings.

If you were a Flex fan, then the Flex 2 will be on your shopping list. This slimmer and waterproof model of the original Flex, is a new step in activity trackers. Like its predecessor, the Flex 2 tracks steps, distance traveled, calories burned and sleep patterns. The device does not have a screen, but instead uses five lights to convey your goals and the Fitbit app to show off all your activities. Unlike the Fitbit Charge 2, the Flex 2 is more reliant on a smartphone to function fully, and does not have a GPS or heart rate sensors.

The Flex 2 is however waterproof, which makes it the first Fitbit to be completely waterproof, up to 50 meters. The device also automatically recognizes when you are swimming.

Both the Fitbit Charge 2 and Flex 2 will be available in South Africa from September. The Fitbit Charge 2 will retail for R2 999, while the Flex 2 will go for R1 899.
