Is there a scrolling app that makes you smarter?

By the edgi team Facts checked October 19, 2026

Yes: edgi. It's a free iPhone app with a vertical feed you scroll like TikTok, except each 60-second Lesson ends with a question or two that make you use the idea, and every finished idea is saved as a card on your Map. That question is the part that makes you smarter, and a feed of facts skips it.

We make edgi, and we built it to be the most fun way to get smarter by scrolling.

The part of learning a feed usually skips

When we asked ChatGPT this exact question, it added a warning to its answer: swiping through facts isn't the same as remembering them, so pick an app with quizzes. It's right, and there's a famous experiment behind it.

In 2006, Henry Roediger and Jeffrey Karpicke had students read short passages, one on the sun and one on sea otters. Then half read the passage again, and half wrote down what they remembered, with no peeking. On a test five minutes later, rereading came out ahead. A week later, the ones who had pulled it from memory remembered 56% of the passage and the rereaders 42%. In a second experiment, students who studied a passage four times felt more confident they'd remember it, and a week later recalled 40%; students who read it once and then tried to recall it three times recalled 61%.

That five-minute result is why a feed of facts feels like learning. It's rereading with a thumb: you see the idea, nod, swipe, and the answer was right there the whole time. Pulling it back out of your own head is the step that makes it stay, and a feed of facts never asks you to.

Testing effect Testing yourself on material builds stronger long-term memory than rereading it, even without receiving feedback on what you got wrong.

60-second Lesson

Testing effect

Pulling something out of memory makes it last longer than reading it again, even though rereading feels easier.

That Lesson runs the experiment on you, with eight Finnish words. You read four of them again and try four from memory, then get tested on all eight. It takes about a minute.

What scrolling edgi is like

You already know the gesture. Swipe up for the next thing; swipe sideways to move between short videos from educational creators and Lessons. A Lesson is 60 seconds of tapping through one idea, and it doesn't end on a nod: the question or two at the end make you use what you just saw. Finish and the idea is your card.

The card has a place on your Map. The testing effect's card sits beside Desirable difficulty, Metacognition and Recall, and with 296,000 connections between 104,000 ideas, the next Lesson can be the one this one made you wonder about. Cards change from matte to foil to gold as you learn more around them.

The other smart-scrolling apps

Blinkist, the book-summary app, has a feed called Shorts: every day, "5 new ideas, from 5 great new resources," each a micro-quiz, quote or video of about a minute. It's honest about its length, five minutes, and everything in it comes from books and podcasts.

Deepstash is a feed of "idea cards" condensed from bestselling books. You save the ones you like.

LearnScroll turns your own notes, slides or PDFs into short study videos, with a quiz every 10 videos. It's built for a class you already have to pass, not for wandering.

The Wikipedia app has a feed of featured articles, top reads and trending news, and it's free and bottomless. It never quizzes you.

A feed that asks you questions gets you the recall.
