In terms of sleep tracking, both of these trackers off a nearly identical experience, and Fitbit sleep tracking is one of the best in the business.īoth devices offer a breakdown of time spent in sleep stages and the duration of your night's rest. On the sensor front, both use a 3-axis accelerometer to track steps, some indoor and outdoor activities and enable sleep monitoring. Though it's clear the Charge 5 can offer you more in some of those departments. When it comes to the job of tracking your steps, sleep, health or exercise, both of these trackers are capable of covering all of those things. The Charge 5 gives you a superior color screen, the same sort of customisable strap options and nicer case materials too if you're not a fan of the all-plastic look on the Inspire 2. The Inspire 2 is the slimmer and lighter of the two, has more versatile wearing options and does offer the ability to mix up the strap options too. A bright screen mode makes it better suited for indoor viewing, you just might struggle to always see it in clear view outside. The Inspire 2 in contrast uses a greyscale display that helps Fitbit to deliver strong battery performance, but we found struggles for visibility in bright sunlight. There's big differences on the screen front with the Charge 5 packing a full AMOLED color touchscreen, which offers an always-on mode. It's a similar story for the Charge 5, which hosts haptic control and additionally includes stainless steel panels to offer the ability to take ECG and EDA readings.

In terms of interacting with these devices, the Inspire 2's case can be squeezed to wake up the display or skip back a screen. Like the Inspire 2, it's been slapped with a 5ATM water resistant rating letting you submerge them in water up to 50 metres, making it safe for swimming. On the Charge 5 you get a much higher-class aluminium case, with a removable silicone band with an array of other official Fitbit bands on offer. A clip accessory means you can wear it on a waistband or underneath your clothes for more discreet tracking. Unlike the Charge 5, you don't only have to wear it on your wrist either.
