This is absolutely the best app to learn flexbox. I've always had huge problems understanding the concept and froggy has helped wrap my head around it. Thank you!

looks like a good tool and I've heard good stuff about it but it doesn't work on mobile

This is a great entertaining game to learn flex box in CSS. My only complaint is that it doesn't work on mobile.

Great learning tool to brush up on your flexbox skills but I wish it worked better on smaller devices.

This the ported version of the open source original. Some ads have been removed and generally made to look more as a web app rather than a website. Anyway, great tool for learning and internalizing flex box in css.
