Have removed the device, uninstalled and reinstalled the app and Fitbit keeps giving an error after the very first step. It says “turn on Bluetooth to pair device”; however the Bluetooth is on both on the phone and on the Bluetooth classic. I have seen the numbers flash to confirm pairing but then I get the error and can’t move forward.

Hello there everyone, thanks for your reports!
@RNHEATHER @ArnoldDownUnder @bananasfoster @leahalex7 @Pfizi @Tktribe8
I have exciting news for everyone! iPhones X/8/8+ have been added as compatible on on fitbit.com/devices.
There is much testing involved in such a process. I highly appreciate all of your patience regarding this matter! All features should be working at a 100% using these iOS devices!
Happy Holidays! ![]()

I figured it out! There was a software update for the Blaze - I had to reconnect to my old phone, do the software update and then disconnect from old and the new phone saw it right away!

Hello @lauramont, @sunshineh, @SunsetRunner and @MikeyO, I hope you're all doing well, it's a pleasure for me to welcome you to the Fitbit Community.
@sunshineh and @MikeyO, thanks for letting me know your issue has now been resolved, I'm glad your Blaze was able to set up in your iPhone X.
@lauramont and @SunsetRunner, at this moment I would like to suggest you the following troubleshooting steps in case your trackers are still unable to pair to your accounts:
I hope this can be helpful, give it a try and keep me posted in case you need anything else. ![]()
Hi. I have done the above. After entering the code on my phone which is given on the blaze I have the following error message (com.fitbithttp error 403). Any advice.
I’m having the same issue as Amararani. Any suggestions?

Best AnswerHaving the same issue with my charge 2 and new iPhone X. I don’t have access to my old phone tho. Frustrating!
Right after I got my new iPhone X, I returned my old iPhone to its factory settings. Should I download the app again on my previous iPhone and unpair my fitbit blaze with the previous iPhone as well??

Best AnswerI just got a new iPhone X and I am getting the same error. Surely someone at Fitbit has a fix for this issue. If not, is there something in the works? I would hate to be forced to leave the Fitbit community because of this incompatibility.

Best AnswerIt is figured out. It does too make a difference. I was in the exact same situation as you and I got it to work. Not fair for you to blame FitBit when they did fix it and it works now. I have had my Blaze connected to my iPhone X since I got the iPhone X in mid November. It works beautifully.

Hey everyone!
@Amararani @Sluck @Amander9448 @stef152 @misterJames @sunshineh Thanks for your reports about this. I wanted to step into this thread and inform you guys that iPhone X is not yet listed as compatible on fitbit.com/devices and that is the reason why some of you have been having difficulties syncing or setting up your Blaze devices to your iPhone X's. Therefore, some or all functionalities may or may not always work at a 100% even after trying @sunshineh's workaround.
If possible, try setting up or sync via a device listed as supported or using a computer. Our team is always working to test and add more iOS devices to the supported devices list, so keep an eye open for updates!
See you around guys. ![]()

Best AnswerI just got my iPhone X. I am not able to sync it with my blaze. I am concerned and would like to continue to use my blaze. Is there a fix?
Best AnswerI have followed the instructions and my iPhoneX still cannot “see” the Blaze as a Bluetooth device 😞
Please help!!!
