Will all the respect to your amazing work, personally I find installing one application in my device (which has plenty of personal info) that I don't know all the thing it does (e.g. might easily include a keylogger or other data collection mechanism) less safe than exposing the code to the scrutiny of hackers. I feel very bad that I cannot help you by testing you nice application. Hope I can continue later in the future.That is, I hope you reach soon the point you can release the code. Thank you again for your time.
