Some lying software is just plain goofy. For example, an iOS app called lets you take one of your actual photos and add an image of a big fish, so it looks like you caught it.

for iOS enables you to a modify a photo of someone to make him look fatter.

A site called will let you type in the dialogue of a fake conversation between you and Apple's voice assistant, Siri. The site will produce a convincing screen-capture spoofing the conversation.

Most of these, of course, are for pranks and fun. But another site is very serious about helping you flat-out lie.
