Blocking your phone while studying
Studying is the hardest case, because the phone is not only the distraction — it is often the timer, the flashcards, the past papers and the group chat where everyone is comparing progress at midnight.
It is also the case where the stakes are most concentrated. A distracted working day costs you a working day. A distracted revision term compounds — and when the term in question is a board year or a run at an entrance exam, that compounding is the entire shape of the year.
What to block, and where the key goes
Four decisions. The last one is the mechanism rather than a flourish: unlocking asks your phone to reach the key over Bluetooth and get a fresh answer back, so the placement that works is one your phone cannot hear from where you are sitting.
Separate the studying tools from the studying-adjacent ones
Notes apps, a PDF reader and a calculator are tools. A group chat about the exam is not a study tool, even though it feels like one — it is reassurance-seeking with a study-shaped label, and it is the single biggest time sink in most revision timetables.
Block video before social
Short-form video is the format that does the most damage to a revision session, because a two-minute break has no natural end. If you block only one thing, block that.
Match the block to a real session, not the whole day
Blocking from 9am to 9pm sounds disciplined and lasts two days. Block the session — fifty minutes, ninety minutes — and unlock deliberately between sessions. A break you chose is not a failure; a break that chose you is.
Hand the key to someone else if you can
A parent, a hostel roommate, a study partner, the desk at the library. Another room works, provided it is far enough that your phone cannot pick the key up from where you are sitting — the same shelf behind you is not another room as far as Bluetooth is concerned. Another person works better still, because retrieving it involves a small social cost as well as a physical one.
The failure mode: the phone is also the timer
People set up a beautiful blocked-off study mode and then keep the phone on the desk because it is running the pomodoro timer — at which point the phone is on the desk, which was the original problem. Use a cheap kitchen timer, a watch, or the clock on the wall. A separate timer costs almost nothing and repays itself in the first session, because it is the one purchase that gets the phone off the desk without an argument.
What if my family needs to reach me?
Keep calls available. This is the correct exception and it costs nothing — the interruptions that damage a revision session are notifications and feeds, not the phone ringing twice a term. If you are studying somewhere with a warden's desk or a housemate who can come and find you, even that exception can go.
Questions about studying
How do I stop using my phone while studying?
Put physical distance between you and it for the length of the session, and decide what is allowed before you start rather than during. Willpower fails most reliably at hour three of revision, which is exactly when you need the decision to already be made.
Should I keep my phone in another room while studying?
Yes, where practical. There is published evidence that a phone's mere presence costs attention even when it is switched off and face down — proximity alone occupies part of your working memory. Another room is a meaningfully different condition from a pocket.
What if I use my phone for flashcards or past papers?
Then keep those apps allowed and block everything else. A mode you cannot revise inside is a mode you will turn off. The goal is not a phone-free session, it is a session where the phone can only do the thing you opened it for.
Four more, each set up differently
Blocking distracting apps for deep work
A two-hour focus block that survives a boring paragraph. What to block, what to keep, and where the key goes so the session cannot be renegotiated.
SleepGetting your phone out of the bedroom
The evening block is the one most people need and the one they abandon first. Why it fails, and the setup that survives the hour before bed.
Family timeBeing present with your family, not just in the room
The block that is hardest to justify and easiest to feel. Three apps, two hours, and the reason a phone face-down on the table still costs you something.
TrainingBlocking your phone at the gym and on runs
Forty-five minutes with music and a timer and nothing else. The one use case where the phone is genuinely needed — and still ruins the session.
If what you want is the method rather than the situation, the guides go deeper, and how it works covers the part that makes all of this hold — the key has to be within Bluetooth range of the phone before it will unlock.

A mode you configure once and stop thinking about.
Locking takes one tap, costs nothing and works with Bluetooth off. Unlocking needs the key — which is wherever you decided to leave it, back when you were thinking clearly. The app is free; the key is the one-time buy.
