StudyDuo
How to not get distracted by phone while studying comes down to one rule: decide before you sit down, not each time the screen lights up. Turn on Do Not Disturb, put the phone in a bag or another room, and block the apps you open on autopilot. In field experiments, steps like these improved attention within one to two weeks.
What your phone does to your studying
A phone costs you less during the session than at the exam. The loss shows up in what you remember later, which is why scrolling feels harmless while you do it.
| Study | Who and what | What happened |
|---|---|---|
| Kuznekoff & Titsworth, 2013 | Students took notes on a recorded lecture; some used their phones during it | Those who left their phones alone wrote 62% more in their notes and scored a letter grade and a half higher on the test |
| Glass & Kang, 2019 | A college course allowed devices in half of its lectures | Quizzes in class showed no drop, but unit exam and final scores on that material fell |
| Marker, Gnambs & Appel, 2018 | A meta-analysis of 59 samples with 29,337 students | Social media used during studying went with lower grades |
Glass and Kang's result is the one to remember. Understanding in class looked fine, so nobody would have noticed a cost at the time. It appeared later, in what students could still recall on the unit exams and the final.
What about a phone lying silent on the desk? The 2017 "brain drain" experiment claimed its mere presence reduces your available mental capacity. Later replications and meta-analyses mostly failed to confirm it, as we showed in Can't Focus at Home? The parts that hold up are notifications and use, and that's where the steps below aim.
How to not get distracted by phone while studying: 7 steps by strength
The steps run from strongest to lightest. Strong steps take the choice away for the whole session; light ones leave you choosing again at every buzz. Start at the top and stop where it works.
- Cut the phone's internet for the session. In a 2025 randomized trial with 467 adults, participants used the blocker Freedom to cut mobile data and Wi-Fi on their iPhones for two weeks. Calls and texts still worked. Their sustained attention improved by about as much as it normally declines over 10 years of aging. The catch: only 119 of the 467 kept the block running as the study required.
- Silence it and put it out of sight. Kushlev, Proulx and Dunn had 221 university students spend one week with alerts on and the phone within reach. In another week, Do Not Disturb was on and the phone stayed in a bag or pocket. In the alerts-on week, students reported more inattention and hyperactivity, and more inattention went with lower productivity. Do Not Disturb plus distance is the cheapest version of step 1.
- Block or time-limit the apps you reach for without thinking. On iPhone, Screen Time decides when apps are available and caps daily time for a category such as Social Media. Contacts and apps you mark as always allowed keep working. In iOS 27 these tools are called Schedules and Time Allowances; in iOS 26 and earlier, Downtime and App Limits. On Android, Digital Wellbeing's Focus mode pauses the apps you pick, and an app timer closes an app when its daily time runs out. Schedule both for your study hours so they switch on by themselves.
- Add a pause before those apps open. The app one sec makes you wait before a chosen app launches and offers a button to close it instead. In a six-week field study of 280 users, people gave up in 36% of their attempts, and actual openings fell by 57%. One of the three authors created the app, so treat it as a promising result rather than a settled one.
- Clean up the laptop too. Close social tabs, log out of the sites you drift to, and add a browser blocker for study hours. In Glass and Kang's course, the devices allowed in lectures included laptops and tablets, not only phones.
- Study where someone can see you. Students who keep picking up their phones often get the same tip from each other: go to a library or a study hall. There, a phone in your hand stands out. A virtual study room does the same at home. In StudyDuo's Focus Room, cameras are on, mics stay off, and a task sits under every name. Step away, and your camera pauses and the room sees you're away.
- Count your pickups for a day. Android's Digital Wellbeing chart shows today's screen time, how often you unlocked the phone and which apps sent notifications; on iPhone, open Settings, then Screen Time. The numbers tell you which of steps 1 to 6 you need first.
How to stop scrolling and study again
The steps above work before you start. For the moment you catch yourself scrolling, a follow-up experiment with 500 people tested which part of one sec's pop-up does the work. An easy way to close the app had the strongest effect, and the short wait helped too. A message asking people to reflect did nothing on its own.
So when you notice you've drifted:
- Close the app at once, without finishing the video or the thread.
- Put the phone face down and out of reach, or in the next room.
- Read the last line you wrote, then write the next one before anything else.
That's the honest answer to how to stop scrolling while studying: make stopping easier than carrying on, and don't count on a reminder to do it for you.
Social media while studying: the overlap is the problem
Most advice on how to not get distracted by phone while studying stops at your own screen, and two findings go further. The meta-analysis by Marker, Gnambs and Appel separated two habits. Using social media while studying went with lower grades (a correlation of −.10), slightly more than general use did (−.07). General use was not linked to spending less time on schoolwork (−.03).
So social media doesn't so much eat your study hours as split them. These are correlations, and weaker students may simply multitask more. The advice holds either way: keep the apps off the device you study on, and reply in one block after the session.
Other people's screens count too. In Glass and Kang's course, exam scores fell for material from device-allowed lectures even among students who hadn't used a device themselves. In a library or a group, sit where other screens are out of your line of sight, and agree that phones stay away until the break.
Apps to keep you off your phone while studying
Start with what's already on your phone, which costs nothing. Third-party apps add locks, friction or rewards. We make StudyDuo, a study room rather than a blocker, and none of the apps below are ours.
| Tool | Works on | What it does | Free version |
|---|---|---|---|
| Screen Time | iPhone, iPad | Schedules limit when apps open; Time Allowances cap daily use per category | Built in |
| Focus | iPhone | Silences notifications except from people and apps you allow; can run on a schedule | Built in |
| Digital Wellbeing | Android | Focus mode pauses chosen apps; app timers close an app when its time is up | Built in |
| Freedom | Mac, Windows, iPhone, Android, Chromebook, Linux | Blocks apps, sites or the whole internet, synced across devices; Locked Mode stops you quitting a session | Yes, sessions up to 2 hours |
| one sec | iPhone, Android, browsers | Makes you pause or breathe before a chosen app or site opens | Basic features |
| Forest | iPhone, Android, Chrome, Firefox | Grows a virtual tree while you focus; open another app and the tree dies | Yes, with ads |
About two in three tools are built around a single kind of feature, a review of 367 self-control apps and browser extensions found, most often blocking:
| Feature | Tools |
|---|---|
| Block or hide distractions | |
| Track your use | |
| Set goals or remind you of them | |
| Rewards or penalties |

The review's authors note that little is known about which designs work best. Few tools have been tested in experiments; one sec and the Freedom block above are exceptions. Choose by what fails you. If you open apps without thinking, use a block or a pause. If you lose track of time, use a timer or a daily report. If the problem is sitting alone with nothing to keep you there, a room of people working is a different kind of fix, and it's what StudyDuo is built for.
Whatever you pick, use it for a week, then count your pickups again and compare them with step 7. That tells you how to not get distracted by phone while studying in your own case, not the average student's. If the phone turns out to be only part of it, the work itself may be the problem: see why uni work is so hard to focus on.
With the phone out of the way, how to lock in for school turns the rest into a daily routine.
FAQ
Does airplane mode help while studying?
Yes: it cuts mobile data, calls and alerts in one tap, the same idea as the internet block tested in the 2025 trial. Its weakness is that it also takes one tap to undo, so pair it with distance, such as leaving the phone in another room.
What if I need my phone nearby for emergencies?
Use a focus setting instead of switching it off. On iPhone, a Focus can let calls and notifications from people you choose through while silencing the rest. On Android, Focus mode pauses only the apps you pick, so anything left off the list still comes through.
Is my phone the problem, or could it be ADHD?
Notifications made ordinary students report more inattention and hyperactivity within a week, so a phone alone can produce ADHD-like distraction. If focusing is hard everywhere and has been for months, not only around your phone, talk to a doctor.
