This app should be a copy of the Apple Phone app look exactly like the one from apple and also work like this. With a small difference: It has two modes: recording mode and display mode.
If the app will be started the first time it is in record mode. I will ask a person to enter his/her phone number but delete it intermediately after entering and the number should be recorded. I will close the app.
When i restart the app the app will be in display mode. The recorded number should be shown in the last digit of the watch ... digit for digit. When I dialed the whole number i simply push call and than the app should call the number. If i restart the app it is in record mode again.
Very simple app which is basically a copy of the phone app. More details i will give to the bidding freelancers.
