Focus Sessions
Set timed deep work sessions with app blocking to keep you in the zone.
About Code Lock
You sit down with a clear plan for the next two hours, and forty seconds later you are reading something you did not choose to read. Not because you are lazy or undisciplined, but because the apps on your phone are engineered to interrupt you and your attention has been trained to accept the interruption.
Code Lock is a focus app built around a simple premise: willpower is a terrible security system. Instead of asking you to resist temptation all day, it removes the option for a fixed window of time — then shows you exactly what you accomplished inside it.
Why screen time limits stop working after a week
Most built-in screen time tools fail for the same reason: they ask permission. A banner appears, you tap "Ignore Limit," and you are back where you started with a fresh layer of guilt on top. The friction is cosmetic, so the habit survives it.
Code Lock changes the order of operations. You decide what you are unavailable for before the session begins, while your rational brain is in charge. During the session, the decision is already made — there is nothing to negotiate with.
Built for deep work, not just less screen time
Cutting your screen time is a side effect. The actual goal is uninterrupted blocks long enough to do work that matters — writing, coding, studying, designing, thinking. Those blocks are fragile, and every context switch costs you the ramp-up time to get back in.
Code Lock protects the block itself. A timed session, a blocklist that fits the task, and a clean record of the work when you finish.
One timer, one intention
Start a session with a length and a purpose, so you know what "done" looks like before you begin.
Profiles per kind of work
A writing profile can allow music while blocking everything social; a study profile can lock the phone down completely.
Streaks that mean something
Your streak counts focused sessions completed, not hours your phone sat idle in another room.
Who Code Lock is for
Students who lose entire study sessions to a single notification. Remote workers whose deep work keeps getting eaten by the same three apps. Founders and freelancers whose income depends on output rather than hours logged. Anyone who has tried deleting an app and reinstalled it within a week.
If your problem is not knowing what to do but repeatedly failing to stay with it, that is exactly the gap Code Lock is designed to close.
How a focus session actually goes
Choose a duration. Choose a profile. Start. Your blocked apps stop opening, and if you reach for one out of habit you are routed back to the task instead of into a feed. When the timer ends, the session is logged and your streak advances.
Over a few weeks the log becomes the useful part: you can see which times of day you actually protect, how long your realistic focus window is, and which app you keep reaching for when the work gets hard.

Frequently Asked Questions
How does app blocking work during focus sessions?
System-level controls prevent you from opening selected apps during a session. Attempts to open blocked apps redirect you back to your task until the session ends.
Can I customize which apps are blocked?
Yes. You can create different blocklists for different types of work — for example, a creative profile that allows music apps while a deep work profile blocks everything.
Why don't built-in screen time limits work for me?
Standard screen time limits ask permission: a banner appears and you tap past it. Because the decision happens in the moment you're already craving the app, the friction is cosmetic. Committing to a session up front removes the negotiation entirely.
How long should a deep work session be?
Most people do best starting at 25-50 minutes and extending as their focus tolerance improves. Session logs help you find your realistic window instead of guessing — a completed 30-minute block beats an abandoned two-hour attempt.
Can I use Code Lock for studying?
Yes. A study profile can block social media, games, and messaging while leaving reference or note-taking tools available, so revision sessions stay intact.
What happens if I need a blocked app urgently?
Build your blocklists per profile so genuinely essential tools are never blocked in the first place. The point is to remove the apps that hijack you, not to lock you out of your own phone.
Is Code Lock free?
The core focus timer and basic blocking are free. Premium features like advanced scheduling and detailed analytics require a subscription.
