Sharing doodles and drawings over mobile devices is nothing new. There are plenty of apps that let you do that without any problem. However, you generally have to unlock your phone to use them. LokLok lets you share doodles and notes without even unlocking your phone.
The app basically turns your boring lock screen into a white board that syncs with your friends and family so you can share notes and drawings with them without having to open up your phone or load anything else. Perfect for those times you just need to fire a off a quick message or when you’re supposed to be in a meeting.
“I wasn’t messing about on my phone! See, still locked! You’re so paranoid,” that could be you. Or you could just use it to leave cute little notes on your significant other’s phone. Whatever. The app doesn’t leave a trace, once you erase something, it’s gone for good. LokLok is currently in beta but has fairly good reviews and is free in the Play store for Android devices.
