Scroll
Scroll: Learn AI is a mobile learning app for understanding how AI works. Its official page describes short lessons about concepts such as tokens, prompting, hallucinations, and safety. It is available on iOS; the publisher says Android is still coming.
Learning one idea at a time
Each lesson card covers one AI idea in about a minute. You can open a longer explanation with a worked example and a limitation or catch. The app uses plain language and does not require math or coding.
That format suits a short learning session. Choose a concept you encounter in your own use of AI, then use the deeper explanation to connect the term to an example. Bookmark a lesson if you want to return to it instead of trying to cover several unfamiliar topics at once.
Choosing an interest track
Scroll organizes its catalogue into eight tracks. These include core concepts, how models work, prompting, practical use, tools, safety and ethics, spotting AI, and recent releases. You can state your interests and starting level to influence the feed.
The publisher says the What's New track refreshes monthly. Treat that as a way to find topics to investigate, while the core lessons provide background for understanding them. The app teaches about AI systems and tools rather than generating your work inside a chatbot.
Checking understanding
A short multiple-choice question follows each lesson. Correct answers earn XP, and the app tracks levels and daily streaks. Bookmarks collect saved lessons in a personal library. Eighteen achievements reward lesson and streak progress.
Use the quiz to check the specific idea you just read. If the answer is uncertain, reopen the example and identify the distinction you missed. Completing a streak is a record of participation, not proof that a concept is ready to apply in a complex project.
Free and Pro access
The free tier includes five lessons a day and two interest tracks, along with quizzes, streaks, and a daily reminder. Pro unlocks unlimited lessons, all eight tracks, and full deep dives.
Pro offers monthly, annual, or lifetime purchase options. The exact price varies by country and appears in the app before purchase. Check the local option after trying the daily lesson format; Android availability should also be confirmed before planning around that version.
