Google's ability to interpret and translate handwriting isn't perfect. Sometimes you'll scribble a word or take a photo of a restaurant menu on holiday, only to have a garbled mess thrown back at you. To help its "smart" assistants and services, Google has released a new app on the Play Store called Crowdsource. It's a bare-bones affair, asking you to transcribe digital squiggles and photographed road signs. There are no discernible rewards, only the occasional message ("you're great!") and meaningless 'milestone' when you've completed a certain number of tasks. In short, you'll need to really love Google to open the app more than once.
