Multichronos app for iPhone and iPad

This app allows you to time up to 3 participants in a race event.
It is easy to follow the turns of the various competitors by the use of large buttons that do not need to look at the screen to validate their passage.
The use of the internal clock of the telephone avoids any shift of the chronometers even in case of very close turns. The timing continues even with the phone on standby.
Competitors can be identified by name or photo.
All partial times are stored and can be sent as a file by email.
