what is the difference between a fitbit versa and a fitbit ionic?
The Fitbit Ionic has better battery life than the smaller Fitbit Versa (five days promised versus four days), a better screen, and GPS built-in. On the flip side, it is bigger and bulkier, so keep that in mind if size is a concern. The Fitbit Ionic gets discounted regularly to $200 (don't ever pay more than that).
