We chose Duolingo for the daily futures, It's an app for learning languages (a culture/education subject), and has good user experience design.
The graphic interface is very simple and minimalistic, and breaks down everything into small sections and lessons - which make something which is very difficult seem very easy. The visual + audio way of learning makes it easier for those who are visual learners, as opposed to how it would be in a classroom setting. It's using the web/app format as a different way to learn something that can be very helpful in everyday life.
It has goals, clubs (to connect with your friends and see how they're doing) and rewards which are an incentive to keep learning it - and you can learn lingots to buy 'clothes' for the owl character. This gamification makes it fun and interesting.
The lessons are in short 5 minute sections, so it can be done waiting for the bus, for example. The lessons also adapt to you - so if you're in a place where you cant speak, it will stop prompting you to speak back.
It also teaches you in a variety of ways, both asking you to translate from english > spanish and the other way, to translate from hearing, choosing the words and typing them yourself. There is a progress bar at the top, which goes backwards if you get something wrong - and then uses that word a lot more until you get it right every time, not just once.
