Just to make sure: My Contact Find needs to read all of your address book data in order to search it. But it never ever sends that data anywhere. The contacts data stays inside the app and can't be read by anybody else (thanks to the iPhone sandbox environment).
See the values of the built in device sensors all together in one app. Supports (if available) acceleration, heading, position, altitude and speed. In addition it gets the current location name and the elevation from the GeoNames database and and the local outdoor temperature from World Weather Online via the internet.
A chess clock consists of two connected clocks which can't run at the same time. Use it as a game clock to measure the time used by two players for their moves e.g. in game of chess. Stopping one clock will start the other one. The purpose is to keep track of the total time each player takes for his or her own moves, and ensure that neither player overly delays the game.
Features:
choose the same time for both players or individually
Measure the time you work and calculate your earnings. The timer keeps running even when you close the application. So there is no need to keep it open all the time.
You can save a history of calculations locally on your phone and email them to yourself for backup and further processing.
