The biggest struggle when contemplating a tattoo is knowing what it’ll look like when it’s actually on you. This app makes the decision a little easier. Ink Hunter lets you try out different pieces from its gallery of pre-made sketches, or you can upload your own. You simply draw a smiley face on the area you want your tattoo, point your phone’s camera, and the tattoo will be overlaid onto your skin. With this, you’ll know how a tattoo will look before you get it inked. Download the app for iOS here.
