Over all a very well made app even in (beta). A few things to work on as all beta's have. the few issues I noticed with it is after first launch you may not get a tikl network connection. The application still has problems with the breaking up of voice transmissions. this is on a issue but would be a better feature for it to have when you first get a in-comming call there is no play back option. so the first message is missed. the last issue i have seen is the application wont work until it is opened. When these issues are resolved by a final release it will be a amazing PTT application.
