So the first app has been submitted to the app store for review.
Its called 5pm somewhere and basically it tells you where it is 5pm in the world. It tells you how far away it is, how to say Cheers and a little fact about the place.
You can get this information on the iPhone or on your apple watch.
It does use your location to work out the distance to the place so please give it location access.
I will add a link when it is approved in the appstore but here is a sneak look…
