iOS: Know Fast for iPhone delivers short (less than four minutes), informative videos to you each day, in categories you choose. It’s a great way to spend a few minutes learning something new and interesting in a field you’re interested in, or just to expand your horizons a bit.
The app itself is fairly simple. Once installed, select categories that interest you, like technology, science, finance, cooking, culture, history, DIY, and more — then watch a short video from one of those categories. Rate it, so the app can deliver better ones to you in the future, share it with your friends if you like, and then sit back and wait for a fresh video to be delivered to you tomorrow.
If it seems a little slower than, say, going to YouTube and binging on all of the DIY videos or services like previously mentioned Brain Pump, it’s intentional — the goal is to give you a quick way to learn something interesting in a short period of time between other things, so it’s easier to make room for it. The videos are also hand-picked, too, so you get good ones (even better if you help rate them.) It’s a quick, simple way to explore a new field, or just make your commute home or idle time more interesting — and educational. The app is free, and available now.
