Cloning humans seems to be impossible, if not immoral, beyond the realms of sci-fi. So how do you clone your best friend, so that in case something happens to them, you still have one left?
I highly recommend Split Lens 2 Pro. It won't actually clone anyone, but a short video or picture of your pet duplicated is enough to multiply the size of your heart. This handy app with loads of split and color effects and lets you export to high resolution. Normally $0.99, but today it's FREE.
