The actual problem
You rarely plan to scroll in bed. The decision happens after your guard is already down.
11:04
You open one app for a minute. The stopping point keeps moving.
12:17
The rule you set earlier suddenly feels negotiable.
7:06
The same loop gets first claim on your morning.
How it works
Three decisions, made before temptation.
Twilock is deliberately smaller than an all day productivity system. Set the boundary you actually need, then get on with your life.
Choose your windows
Set a Night window of up to two hours. Pro adds a second focused window for the morning.
Let Twilock enforce them
When a window starts, your chosen apps are shielded. Strict Mode adds stronger commitment when you need it.
Privacy at a glance
What Twilock can and cannot see.
Twilock needs Apple’s Screen Time authorization to apply the shields you schedule. Apple keeps your selections private, and Twilock keeps the core data on your iPhone.
You approve access
Twilock asks for Screen Time authorization before it can apply a shield. You can revoke that access in iPhone Settings, which stops the protection.
Your choices are opaque
Apple represents the apps and categories you choose with opaque values. Twilock can apply your shield without receiving readable app identities.
Core data stays on your iPhone
Your selected apps, raw Screen Time activity, and Night or Morning window settings stay on your device. Optional account and social data is covered separately in the privacy policy.
Strict Mode
A promise that is harder to renegotiate at midnight.
Normal blocking helps when you want a reminder. Strict Mode is for the nights when you already know a five second settings change will win.
- Available with Twilock Pro
- Protects an active window from impulsive edits
- Stops Twilock from being deleted mid session
- Always leaves a recovery path for genuine need
Strict Mode is a commitment tool, not parental control software or an emergency service. Leave essential apps outside your blocked set.
“I made this rule while I was thinking clearly. Keep it.”
That is the whole idea: your earlier decision gets more weight than the impulse that arrives later.
Night to morning
Protection at the edges of sleep.
A sample schedule not a prescription. You choose the times that fit your life, with each window capped at two hours.
9:30 PMWind down begins
10:00 PMNight window starts
12:00 AMNight window ends
7:00 AMMorning window starts
8:00 AMStart the day on purpose
Why Twilock is different
A focused blocker, not a productivity universe.
Twilock does not try to manage every minute of your day. It concentrates on the two recurring moments when scrolling is most likely to take more than you intended.
Two named windows
Night and Morning make the job obvious. No elaborate rule system is required to protect the hours around sleep.
Commitment without shame
The product adds friction to a choice you already made; it does not pretend that distraction is a character flaw.
Useful free tier
The Night window, streaks, badges, milestone Streak Freezes, weekly Snooze Token, friends, leaderboard, and reclaimed hours count are free.
Private Screen Time data
The app cannot see which apps you picked or how long you use them; that Screen Time data stays on your device.
Pricing
Start with your nights. Add more commitment when you need it.

Independent product
Built by the person who needed it.
Twilock is built by Hussain Taheri, a University of Florida computer science student. It started with a narrow problem: knowing exactly what a screen time blocker should do at night, then turning it off anyway.

Before you set your first window.
What does Twilock block?
Twilock uses Apple’s Screen Time framework to shield the apps or app categories you choose during your scheduled Night or Morning window.
Is Twilock free?
Twilock is free to download. The Night window and core streak features are free. Morning windows, Strict Mode, Streak Repair, and deeper insights require Twilock Pro.
Can I block apps all day?
Twilock is intentionally not an all day blocker. Each Night or Morning window is capped at two hours. If you need workday rules, usage budgets, or cross device blocking, a broader tool may fit better.
Can Strict Mode be turned off during a window?
Strict Mode is designed to stop impulsive edits and prevent deletion of Twilock during an active session. It still includes a recovery path for genuine need.
Does Twilock upload my Screen Time data?
No. Your chosen apps and raw Screen Time or app usage data stay on your device. Optional account and social features use limited server side data as described in the privacy policy.
What iPhone version do I need?
The current App Store listing requires iOS 16.0 or later.
