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

Scroll Myself
to Sleep

Live

You've been locked in all day. Now you're going to bed — you deserve to scroll. Activate Scroll Myself to Sleep and Lock In gives you a controlled window of 30 minutes to 4 hours to get your dopamine hit and drift off. When morning comes, everything locks again automatically. A ~20 hour cooldown means it only works at bedtime — not as a loophole during the day. Strict all day. A little slack when it matters.

The reality

Our generation is

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.

The average person spends 2h 21min on social media daily. That's nearly 15 hours a week — 32 full days every year, gone.

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.

Limiting social media use to approximately 30 minutes per day may lead to significant improvement in well-being.

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 24 hours only — 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, no data sent to any server. Lock In never knows what you block, when you unlock, or anything else. All logic runs locally — notification timings, unlock windows, relock schedules, everything. None of it touches a server because none of it needs to.

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. 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.

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.
