Does the environment you wrote it in support networking? If so an interesting option would be two have it run on two phones. Each phone would show both times. This would have two advantages over other phone chess clock apps I've seen. 1. Convenient placement. Each player could have their phone where it is most convenient for them instead of it having to be in the usual place on the side of the board. 2. Others have brought up the concern that people might hit the phone too hard after their move. In a time scramble people do sometimes hit pretty hard because they are trying to hit it as fast as possible. Also, they don't always hit it with relatively soft flesh. They often hit it with the bottom of the piece they just captured. Imagine what repeated hits to the phone from pieces from a tournament sized triple weighted set could do. If each player is hitting their own phone they might be more careful.
