You were answering what is essentially a product recommendation question. The question should have been closed. It is also asking how to do it for a mobile device, another off topic reason.
Your answer was useful in itself but felt to me that it was not answering the question, the off topic product recommendation, as it was asked.
So I converted your answer to a comment.
