Lifestream Learn
Short-video learning, with interactive cues that actually stick.
What it is
Lifestream Learn is an Android-first educational short-video app where videos pause at authored moments and ask you to answer: multiple-choice questions, fill-in-the-blank prompts, and matching exercises. Designers publish courses; learners scroll a feed and practice as they watch. The entire stack is open source under AGPL-3.0, so you can also run your own instance.
