## Questions & Answers

**Q: Does it come with charger or do you have to buy separately?**
A: It comes with a charger.  I have not been able to buy it separately.  You have to buy a whole new Flex 2.

**Q: Will this recognize activity from stationary cycling?**
A: I don't think any one of these people really answered your question. It is not going to recognize that you are cycling and it will just run up your step count. I find this to be a problem because I am not taking any steps when I am riding my bike and don't want that counted as walking.

**Q: do you have to have the app or a phone**
A: If your phone is not compatible with the device (as mine was not compatible) then you MUST purchase a dongle to go with this particular tracker as it is not included in the purchase of the Fitbit Flex 2. With a dongle plugged into your computer, you pull up the Fitbit icon on your computer and tell it to sync if it has not synced in a while....but it will sync from time to time on its own. If your phone does work with the tracker, then you just download the app and you are set to go.

**Q: Does this fitness tracker touch the skin?  If so has anyone with a nickel allergy worn it for a substantial amount of time?**
A: I have a severe nickel allergy -- rash, swelling, blisters.  But the Fitbit Flex 2 band doesn't irritate my skin at all, even though I've been wearing it 24/7 since I got it.  Granted, only the two little posts that secure the band (not the tracker itself) have any metal that touches my skin, but usually that would be enough to set my wrist on fire.  When I researched before buying, the only official word I could get from Fitbit said the clasp is surgical grade stainless steel, which by definition shouldn't have any nickel in/on it.

### ⭐⭐ Not as described
*by S***D on 6 March 2024*

The device looks amazing, stylish. Battery life is 24-36 Hours not even close to 2 days and they claim 5 days . The charger cable got broken on the 1st week. In short - Great design, poor performance.
