Well, I checked it out just now, and if i'm not mistaken it is not free. I found something everyone can use for free, and i don't think its worse than the ReptileScan. I'm pretty sure both apps have similar features, just that one is free and the other one you have to pay for, because it has "reptiles" in its name hehe. I think apps such as VueMinder are just as effective, as ReptileScan
