Clock Name bug
I discovered a bug when entering a Clock Name that uses a space such as "New York". After using a space I am unable to enter any more characters - the keys no longer worked. But, I could get around this by exiting the app and starting it again and continuing the "York" part of the clock name.
Other people that only include cities without a space in the name would not encounter this bug.
So far, a good & practical app otherwise as I have only used it for 20 mins.
