New Knowledge + Short Videos + Daily Habit = Happiness
Science has proven that lifelong learning is a recipe for becoming happier, healthier and smarter.
We are all familiar with the idiom “A picture is worth a thousand words” referring to the fact that a complex idea is conveyed much more effectively and quickly using a single still image compared to a description. Watching educational short videos offers a whole new dimension to learning.
Know Fast combines these concepts and allows you to create a new habit of improving your understanding of the world surrounding us.

Ratings and Reviews
I used to love this app. NOT any more!
So it would ring every day at 12. It was loud, but it was like my 12 pm alarm. Then they changed the notification. It rings sometimes at 12, but not every day. If I opened my phone at any time after 12, it rang again! Loud and obnoxious. I can't open my phone in the office if it's any time after 12. So I deleted the app. Pity.
Developer Response ,
We are sorry to hear you have deleted the app :(
Usually if you set a notification to 12 than it will pop at 12. Sometimes when there is no connection or the device was turned off, the notification can pop once connection was gained or device turned on. In any case you can turn off the sound of the notification from the settings screen. If you would like to reinstall, we will be glad to assist you with the settings.

I love this app & it's quick videos. I would however like to see 2 a day. Also with the latest update - it cleared the videos I already watched & now I can't go back to get the information from one that I wanted. A backlist would be great too, to narrow down the topics. I don't care about history or computer science.....
I've learned lots of new stuff! Great app.
Short videos, everyday. Quick and to the point. For people who wants to learn fast. Most videos are very interesting and diverse.
