Learning and memory
Apps to replace doomscrolling, by how they work
Short answer
They work in one of three ways. A learning feed gives you something else to scroll, a blocker puts a pause or a limit in front of the feed, and a reading app swaps many short posts for one longer piece. One blocker, one sec, has a published field study; Scroll, our app, hasn't been studied. Apps built on streaks can become a new reason to check your phone.
Doomscrolling here means reading an endless feed, often of bad news, for longer than you meant to. Online adults spend well over two and a half hours a day on social and video platforms, about 18.5 hours a week, according to GWI data in DataReportal’s Digital 2026 report (published October 2025). Apps sold as a replacement for some of that time step in at different moments: when you pick up your phone, when you tap a feed’s icon, or when you have 20 minutes and nothing planned.
Below, they’re grouped by that moment. Every app named here was checked on its own US App Store listing or website on October 17, 2026, and every price is the US price on that date. Scroll is ours, and it sits in the first group.
Three ways these apps work
| Type | What changes when you reach for a feed | Apps checked | The trade-off |
|---|---|---|---|
| Learning feed | You scroll short lessons, stories or idea cards in a different app | Scroll (ours), BrainScroller, Chunks, Deepstash, Nibble | You’re still scrolling, and some of these feeds don’t end either |
| Blocker or app gate | A pause, a wait or a limit appears before the feed opens | one sec, Opal, ScreenZen | It gives you nothing to do once you’ve backed out |
| Reading app | You read one longer piece in place of many short ones | Libby, Instapaper, Wikipedia | It needs a few spare minutes, not a few seconds |
You can use more than one. The last section shows how a gate and a feed fit together, since they act at different moments.
Learning feeds give you something else to scroll
A learning feed keeps the swipe and changes what’s under it. The five below differ most in length, in whether a question follows each item, and in how much the free tier covers. “Not mentioned” means the listing and website we read don’t say; the feature may still exist.
| App | What you scroll | Length, as the app states it | Question after each item | Streaks | Paid plan (US) |
|---|---|---|---|---|---|
| Scroll (ours) | 1,700+ lessons in 8 categories | 21 to 115 words, 32 to 50 seconds | Yes, one question with four options | Yes, plus XP and 42 achievements | $3.99 a month or $19.99 a year; the free plan has 5 lessons a day |
| BrainScroller | 1,800+ idea summaries in 7 topic areas | No figure given | Not mentioned | Not mentioned | $4.99 a month, $34.99 a year or $99.99 once |
| Chunks | Narrated stories you read or listen to | About 5 minutes on its site; under a minute in its store description | No, by design | Yes | $9.99 a month or $49.99 a year |
| Deepstash | Idea cards from nonfiction books, articles and podcasts | About 5 minutes a day | Not mentioned | Not mentioned | Pro listed at $12.99 to $19.99 a month or $29.99 to $119.99 a year |
| Nibble | Interactive lessons, plus games, chats, video and audio | About 10 minutes in its store listing; 3 to 10 on its site | Yes, questions inside each lesson | Not mentioned | Listed at $19.99 a month; yearly plans from $12.99 to $89.99 |
Scroll is our app, so weigh that row accordingly. Its lessons are the shortest stated length in the table, and every one ends with a four-option question and a one-line explanation. Five lessons at the median 44 seconds come to about 3.7 minutes of reading, which is also where the free plan stops for the day. It has no audio, no book summaries and no languages besides English. Here is one of its lessons, with the question as it appears in the app.
The Attention Economy
Herbert Simon observed that information abundance creates attention scarcity. Every business on the internet competes not for money first, but for attention. Attention, once captured, can be monetised (advertising) or converted to purchase intent. This is why TikTok's algorithm is so valuable, it captures attention with superhuman efficiency. The cost: human time and cognitive bandwidth.

Quick quiz
Every app on your phone, whether it sells products or just shows content, competes for the same scarce resource. What is it?
The others make different trade-offs. Chunks narrates every story and leaves quizzes out on purpose, which suits listening while you walk or cook (the examples its listing gives). Nibble’s lessons are longer and closer to a short course. BrainScroller and Deepstash are nearest in shape to a social feed: a run of short cards that keeps refreshing, with saving and collections, and in BrainScroller’s case an AI guide for explanations.
None of the five listings we read cites a study of what the app does to time spent on other apps, and we haven’t tested that for Scroll either. Scroll lessons are short introductions for general interest. They aren’t medical, psychological or financial advice, and we haven’t tested whether reading them changes anyone’s memory or focus. For a decision about your health or money, talk to a qualified professional.
Blockers and app gates put a pause before the feed
The second group leaves your feeds where they are and changes the moment you tap one. You choose which apps get the gate, and the gate decides what happens next.
| App | What happens when you open a chosen app | Free version | Paid plans (US) |
|---|---|---|---|
| one sec | A short breathing animation, then the choice to go on or back out; it can also send you out again after a set time, such as 5 minutes | One app | $6.99 a month, $19.99 a year or $99.99 once |
| Opal | Blocks on a schedule or for a timed session, plus daily limits; its release notes describe a waiting room before an app unblocks | Free to download | Plans listed from $4.99 a week to $99.99 a year |
| ScreenZen | A wait before you choose whether to open the app, which can grow each time; optional blocks after a set number of opens or minutes | Yes; the only purchases listed are tips | None listed; tips from $5 to $40 |
Opal’s listing also describes a Deep Focus mode that can’t be canceled or bypassed once it starts, and its App Store version needs iOS 18 or later. ScreenZen lets you lock its own settings so you can’t loosen them in the moment.
What a study of one sec found
In 2023 David Grüning, Frederik Riedel and Philipp Lorenz-Spreen published a field study of one sec in PNAS. They followed 280 people who had just installed the app, for six weeks. Each person chose their own target apps, and social media made up more than 80% of the screened app activity, with Instagram and Twitter alone accounting for half. About 36% of the time, people who reached the pause backed out. Attempts to open the target apps fell 37% between the first week and the sixth, and with both effects together, actual openings were down 57% after six weeks.
A second, online experiment with 500 people tested the app’s three parts separately on real and viral social media videos. The option to back out had the strongest effect, the time delay also cut viewing, and the message asking people to reconsider didn’t work on its own.
Reading apps swap many short pieces for one longer one
The third group asks for more time per sitting and gives you something with an end. Americans aged 15 and over spent an average of 16 minutes a day reading for fun in 2025, against 2.6 hours watching TV, according to the American Time Use Survey from the US Bureau of Labor Statistics. That average includes everyone who didn’t read at all that day.
Libby lends ebooks, audiobooks and magazines from your local library, free with a library card. Instapaper saves articles from the web into a plain text view you can read offline or have read aloud; Premium costs $5.99 a month or $59.99 a year. The Wikipedia app is free. It has a Home feed of trending articles, reading lists that work offline and a random-article widget.
A saved-article queue has one property a social feed lacks: it runs out. When you’ve read what you saved, there’s nothing new until you add more.
The catch with streaks
Several learning apps count streaks, Scroll included. Scroll’s is the number of days in a row you’ve read at least one lesson. A streak gives you a reason to open an app every day, and a daily reason to open an app is close to the habit you were trying to change.
Duolingo’s numbers show how strong that pull can be. In June 2026 it ran a one-time event that let eligible learners restore their longest-ever streak if they opted in and completed three lessons. According to its second-quarter shareholder letter, 15.4 million learners revived their streaks, and nearly 8 million of them had no active streak when the event began.
The research on habits is more forgiving than a streak counter. In Lally and colleagues’ 2010 study of new daily habits, missing a single day did not derail the process. Scroll’s streak resets after a missed day, though your XP and achievements stay. If you notice you’re opening a learning app to protect a number, the same tools apply to it as to any feed: turn off its notifications in your phone’s settings, or put a gate on it.
Using a gate and a feed together
One setup: put one sec or ScreenZen on the two apps your phone’s screen-time settings say you opened most yesterday, then move a learning or reading app into the home-screen spot one of them used to fill. When the pause appears, the alternative is one tap away.
Small amounts add up in either direction. Ten minutes a day comes to 3,650 minutes a year (10 times 365), which is about 61 hours.
