Which Should You Buy?

Charge 4 will cost you more, but I think it’s a better bargain than Inspire HR. It’s a better smartband than Inspire HR, as it comes with NFC that supports Fitbit Pay, the ability to control music on Spotify, has a longer battery life, has inbuilt GPS, and is equipped with more fitness tracking features.

Inspire HR is still a decent choice if you have a tight budget.
