I don't think mining a coin on mobile is worth or not, what is the cost of a mobile phone as compared to mid-range GPU? Everyone has his own choices but I'm not really convinced about the mobile mining concept.
I don't think you get the idea behind this "mining"
It's just a simulation of mining, you'll not use the resources of your smartphone, you'll gain a little amount of coins, just installing the app and enter some days. It's just part of the marketing for the company / coin, to achieve more users
