LOCK IN
Stop killing time.
Why Lock In

Simple to use.
Impossible to escape.

Every other blocker has a back door.
Lock In doesn't.

Setup in two minutes
No account. No server. No email required. Pick your apps, choose how you want to unlock, done. Lock In doesn't need anything from you except five taps.
Actually strict
Real OS-level blocks — not a VPN overlay, not a passcode you set yourself. The app genuinely cannot be opened. Blocked is blocked, full stop.
Personalised to you
Choose which apps to block, how you unlock, how long before it relocks. You set the rules. Lock In holds them. Even when you'd rather it didn't.
Scroll Myself to Sleep
Going to bed? Activate it and get a guilt-free scroll window before everything locks for the morning. Strict all day. A little slack when it matters.
Front-load your discipline
Set the rule once. Lock In enforces it forever. You don't have to be strong every time — just once, when you set it up. It holds even when willpower doesn't.
No tasks. No lectures.
Other blockers make you breathe, journal, or touch grass. Lock In just blocks your apps and gets out of the way. Comfortable to use, impossible to escape.
Our Unique Features

A mode for
every part of your day.

Focus
Mode
Live
Need to actually get something done? Start a timed deep-work session and your distracting apps stay locked until the timer runs out — no early exits, no "just five minutes." The block screen even switches to a focused look that keeps you in it. When the session ends, you're done — go do the thing.
Morning
Lock
Live
Win the first hour of your day. Morning Lock keeps your distracting apps locked when you wake up, so you get up and get going before you get online. No doomscrolling in bed — it only lifts once you're properly up and moving.
Scroll Myself
to Sleep
Live
You've been locked in all day. Now you're going to bed — you've earned a scroll. Activate it and Lock In gives you a controlled window of 30 minutes to 4 hours, then everything locks again automatically for the morning. An ~20-hour cooldown means it only works once a day, at bedtime — not a loophole during the day. Strict all day. A little slack when it matters.
Creator
Mode
Live
Need Instagram or TikTok to actually post, not scroll? Creator Mode gives you a temporary, partial unlock for the apps you create in — so you can publish, reply, and get out, without opening the floodgates on everything else.
Your
Streak
Live
Every day you stay locked in builds your streak. Watch it grow, protect it, and share it — a simple, satisfying reason to keep showing up for yourself, day after day.
The reality

Our generation is
cooked.

We're not talking about occasional distraction. We're talking about years of your life, quietly handed over to an algorithm designed to keep you scrolling. The data is damning. Stop killing time before time kills you.

36
days a year.
The average person spends 2h 21min on social media daily. That's over 16 hours a week — almost 36 full days every year, gone.

3hrs+
every single day.
Adults aged 18–24 average over 3 hours of social media daily. Teens average 4 hours 48 minutes. Every day.

7x
higher depression risk.
A study of over 7,000 young people found depression risk increased up to 7x with increasing smartphone use — with anxiety and sleep disturbances rising in step.

FAQ

Questions we
actually get asked.

You have 3 emergency unlocks per month, and they reset on the 1st. For real emergencies, that's more than enough — and the limit is intentional. If you had unlimited emergency unlocks, they'd stop being emergencies. Note that an emergency unlock opens your apps for up to 23 hours — after that, everything locks again automatically. If you need access to a specific app to deal with something urgent, we recommend removing just that app from your blocked list instead, handling what you need to handle, then adding it back.
Yes — you choose exactly which apps get blocked. Phone, Maps, Camera, Messages — anything you need stays fully accessible. Lock In only blocks what you tell it to. We recommend adding all social media apps and anything you tend to open out of habit or boredom — the apps that eat your time without giving much back.
Completely. Everything stays on your device. No account required. Lock In never knows what you block, when you unlock, or anything else — all logic runs locally: notification timings, unlock windows, relock schedules, everything. The only thing that ever leaves your device is feedback you choose to send us, which goes through our own relay straight to our inbox. Nothing else, ever.
I use and recommend Sociallite — an app that lets you see your feed and inbox across social platforms without the infinite scroll. Because it runs on the web versions of each app it can be glitchy for posting or browsing followed accounts, but for replying to friends it works well enough that you won't miss anything important.
Yes — with Premium. Lock In can block specific websites and entire app categories using Apple's Screen Time framework. Block Instagram the app, the website, and the whole social media category — all at once if you want. (The free plan covers up to 3 individual apps; website and category blocking is a Premium feature.)
Founder talk

Built for myself first.
Turns out I wasn't alone.

I've been on social media since my teenage years. A few years ago I realised it had gotten out of control — not in a dramatic way, just in that quiet, persistent way that's harder to notice. It was bad for me, and I knew it.

I tried a lot of apps to help. Some were decent. Some were genuinely terrible — one had me doing push-ups in the middle of the night just because I wanted to scroll before sleeping. None of them were quite right. None of them worked the way I actually needed them to.

So I built my own. Primarily for myself, exactly the way I wanted it. After using it for a while and seeing real results, I decided to share it — because I know there are millions of people in the same situation, or worse. I added more features, built in more personalisation, and started thinking seriously about where it could go.

Now it's up to you. I'd genuinely love to hear your thoughts — what you'd want to see added, what's missing, what would make this work better for your life.

The founder's setup

Here's exactly
how I use it.

Steal whatever works. Skip whatever doesn't.

Blocked apps
Instagram, TikTok, YouTube, Twitter / X, Facebook — everything I'd open out of habit, not intention.
Unlock method
I switch between NFC card and tap-to-hold depending on where I am. NFC at home, hold when I'm out.
Relock timer
4 minutes. I can't count how many times I've gone in to post something and ended up scrolling — 4 minutes catches me in 4K every time.
Unlock cooldown
9 minutes. Just long enough that by the time I could unlock again, I've already started doing something else.
Scroll Myself to Sleep
1 hour 45 minutes, turned on around 1am. I wake up at 10am to everything already locked and go straight into something productive.
Responding to DMs
I use Sociallite — you can see your feed and inbox but there's no infinite scroll. It runs on web versions of each app so it's glitchy for posting, but for replying to people it does exactly what I need.
Reviews

word for it.

"For a whole day it didn't even cross my mind to open TikTok. I knew it was blocked, so I just didn't. I found other things to do — on my phone and in real life — and got a ton done that I'd normally keep putting off."

"Lock In is the app I've been missing this whole time. Scroll Myself to Sleep is so cool — I've never seen anything like it."

★★★★★

"Honestly? It's annoying. It just won't let me weasel out of it — and that's exactly why it works. I can't say a single thing against it."
