Question: what is the difference between a fitbit charge 3 and a fitbit versa?
Answer: The Versa is built like a smartwatch, with a wider display intended to let you see and do more things. The Charge 3, on the other hand, is built more towards being an exercise companion and little less in your way. Yet they both also have things like waterproofing, a heart rate sensor and an SpO2 sensor.
