Stopped pairing when changed phone to iPhone 7

*Updated Review*

I've updated my phone to iPhone 7 and surprise surprise, I have deja vu all over again. The watch refuses to pair with my iPhone. The app hasn't been updated since last year. Safe to say I won't be buying a G-shock with Bluetooth again! The Apple Watch looks like the smart choice to pair with your iPhone. Forget the G-shock range Casio don't want to support the app!

*Old review 2015*
Wrote a review two days ago out of frustration with the previous version of this app, the app did not work with iPhone 6. I am now pleased to say that my GBA 400 pairs with my iPhone 6. Can now fully enjoy all the features of my watch. Have not fully tested this out but things look promising. Casio has finally sorted this out.

It does not work!!!

The watch can only be adjusted by the application and it doesn’t work with all versions of Apple iPhone operating system. Please be aware before you purchase the watch. Utterly frustrating for something that should take less than a minute!!! SHAMEFUL

Loose stool water

Seriously, sort the app out. It is absolutely pants. It won’t pair with the watch, is glitchy when it does, and if I had known this prior to buying the watch, I wouldn’t have bothered. Loose stool water is the best description I can give of this app at the present moment in time.
