NoTrample

The app has two features:

1. It can detect dangerous crowd you have located in the outdoor, whenever you have on the spot of the event or on the road to the event spot, if there are enough people around you have install the app;

2. If the density of the crowd reaches the risk critical, it will send different warnings to people locating different positions in the crowd in the order from outer to inner with certain long interval.

The app are just used in the situations where people are taking part in the public events, so it is used with extremely low frequency and has hardly economic values, but in some situations it can save lives.

The server that acts as data centor for the app is stopped, unless there are managers of public events send an email to me that they will hold a public event and need the server to be run: [email protected].
