Hi there @RQ, I hope you're having a great day, it's nice to see you around. 

If your Blaze is not syncing with your iPhone 7 I would like to suggest checking @HelenaFitbit's excellent tips and recommendations that have been proven to be very helpful for many members in the Community dealing with the same situation. 

In case these steps don't seem to work, my best recommendation would be setting up your tracker as a new device. Don't worry, none of the information already stored in your account will be deleted.

To set up your tracker as a new device:

1. Go to the Bluetooth settings on your phone and check if your tracker is on the list of paired devices. If it is, tap on it and select Forget this Device.
2. Restart your phone.
3. Restart your tracker once again by pressing and holding the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen. Then, charge your tracker by plugging it in to an USB port
4. Make sure there are no other Bluetooth devices around that might interfere with the syncing process. 
5. Try to set up the tracker as a new device. 

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