I just bought it after seeing this. Its pretty neat. I mean its really just paying for the fancy interface mostly. Though it feels very nice and sleek, great UX so far. The
reviews on it on GPlay kind of sketchy, seem paid for. Though it very well could be a close group from beta test, they probably are from a private community on Google Plus.
One thing I think is pretty neat is it has a decent database of RBAs and when you select one, there is an option to see a list of suggested coil setups that you can rate and download to try out. That is pretty cool I think, as long as it grows and is used.
I say give it a shot. Seems to have everything Vapers Toolbox has in regards to its coil calc, but much cleaner interface and some neat additions.
