A:AnswerIt is compatible with iPhones. I have an iPhone XR and it works great! There is a Fitbit app you download that displays all the information that the watch collects. You have to connect your Fitbit to your phone through Bluetooth and you can receive certain notifications like text messages, calls, emails, and more. With your watch, you can answer calls but you still have to talk through your phone but you cannot answer text messages through the watch with an apple phone like an apple watch. If you have an android, I believe you can reply to texts from your Fitbit. I hope this helps!
A:AnswerThere is a limited selection of pre-worded responses available right from the watch. Works on my Samsung Note 9, as long as the watch does not lose connection, which happens all too often.
