The idea behind Tattoo, of placing a digital tattoo over an image of your arm, leg, back, or wherever, is a fantastic way to prepare for tattoos and ensure you get the right one in the right location.
Tattoo is a well-designed app that is relatively easy to use. Open the app and either take a photo or choose one from your library. Then choose an image from the tattoo library and drag it to where you'd like to see it placed. Then rotate and adjust size to get it just right. The entire process is quick and easy and the results are surprisingly lifelike--potentially making for some hilarious photos as well as planning for your next tattoo. The tattoo app works quite well, but it has a major drawback in that you only get a small handful of tattoos to choose from, with the rest requiring in-app purchase to view. In fact, only the letters and numbers are free with every other pack requiring a purchase, and there is no option for installing your own tattoo graphics or altering the ones that are already there.
Tattoo is an easy-to-use app limited only by the number of graphics. If you know you are getting a tattoo soon and are interested in the art in these packs, it is a good fit; if you are just experimenting, there are others with more free options.
