Screencastify recently updated and now integrated with a variety of other apps. This process (formerly called “appsmashing”) is when you take 2 or more applications and combine their uses (and I currently can’t help but think of Captain Planet right now).
Screencastify can now app smash with a few other awesome tools such as Edpuzzle, Wakelet, and Remind. Once you record and create your flipped video/screencast you can directly upload it to one of those apps just by signing into that account via Screencastify. Check this out!
Hope this helps!
