Android App for website?

Hello guys,

I´ve my own website of tarot telefonico 24 horas is in Spanish, the translation would be “tarot in telephone 24 hours”

I´d like to have a great android app, because my clients need to be in contact with me faster and in an easier way so, I saw tools in Internet to do this fast and cheap, but I readed about native apps and I think that is what I need.

What do you think guys?
