First: this Progrm was written in 3 days for Code Geist hackathon 2018 (not the best thing ) but i am proud with my team that we made that with this idea.
Second: some of open library we use all thier © recived for the real owner
Third:may be in the future we back to develop this project more with our own library this time 😊 ( or at least by myself i still put that in my mind )
thanks
