It would be great if there was a watch app.

Worked for awhile. Now I can’t login. It says click I agree to the license agreement but that button doesn’t even show up. Smh

So Happyrun says to use the SmarGoo app which is basically the newer version of the old happyrun app which stopped at version 1.0. Unfortunately, when they decided to move over to SmarGoo to support More bike and computers, they still do not support all of the models that are made by happy run. I.e. when I add my G 100 Pro it tries to add it as a G 50. Some functionality works like the mapping and the ability to lock and unlock the bike. However, when I unlock using the app parts of the display do not work, which makes me wonder if the computer thinks It’s a G50 and therefore you’re going to limit your ride functionality using the app to unlock. Because now the computer thinks you’re on a G50 instead of a G 100 Pro. In short, this app is woolly behind the physical production of the bike. The bikes are great, but the app support sucks. If you get locked out of your bike and you’ve already synced using this app, at least you can get into your bike if you lose your NSC cards.. Using NFC tool to try to copy your NFC cards does not work because the NFC cards that happy run uses are not readable by iPhone NFC reader. These guys have a lot going on and they need to think of all their stuff to make it work together.. As of right now, I would give this apple one simply because it unlocked my bike but beyond that is a useless piece of crud.
