Yes it is. But honestly it’s not worth it.
CPU’s are not good enough to mine bitcoins. I saw some stats like yoj will mine 0.20$ per day for 24h use. These kind of apps will also charge a small comission which will bring your profit per day at 0.15$ ?
I recommend you at looking at special gear (200$) which will do only one thing, but really good : mining. Maybe mine altcoins which are easier.
By the way I just developed an android application which combines Bitcoin and Clicker Game with simulation. Check it out and tell me what you think, it's still in development :)
