Flex not pairing with iPhone 4.

[NightcoreGamer2]

I was struggling to get my iPhone 4 to pair with the Fitbit Flex. I removed the tracker from the app, and there's no button saying "Set up a Fitbit". Can anyone help me? My Fitbit won't even connect with my other Bluetooth devices, like my iPad.

Hello @NightcoreGamer2, have a warm welcome to the Fitbit Community, it's great to have you on board. :smileyhappy

If you're having trouble pairing your Flex with your iPhone 4 might be because the iPhone 4 is not compatible with the Fitbit app, only the 4S is. If you're using an iPad, please check our list of device compatibility to check if your model is compatible as well. 

If the iPad is compatible, make sure that when downloading the Fitbit app, the App Store is set to "iPhone Store" instead of "iPad Store" and keep in mind that your tracker will not pair directly through the Bluetooth on your device, it needs the Fitbit app in order to set up and sync. 

I hope this can be helpful, give it a try and keep me posted in case you need anything else.
