An app that records is no longer enough. Cops are tuned in now. They just confiscate the phone, erase files, etc. Do you have an app which makes the recording and streams the data to an upload site so cops cannot seize your phone and destroy evidence against them once its out of your possession ? Imagine streaming the entire conversation to an upload site, one in which you catch cops conspiring to destroy evidence on top of the fact that they illegally seized your phone and illegally arrested you.
