How does LockLeaf block apps on iPhone?
LockLeaf uses Apple's Screen Time controls on iPhone to block distracting apps. When you want more time, you answer a short quiz to earn a limited unlock instead of relying on willpower alone.
Focus without punishment
Beat doomscrolling
without deleting your apps
LockLeaf blocks distracting iPhone apps, then lets you earn screen time back with quizzes, flashcards, streaks, and rewards that actually make focus stick.

The Doomscrolling Trap
You don't lack discipline.
Apps are just built to trap you.
Existing app blockers feel like punishment, which is why you always end up deleting them. We need a solution that works with your brain, not against it.

FAQ
Questions people ask before they finally fix their screen time
The short version: LockLeaf makes distracted phone time harder to do automatically and easier to use intentionally.
Do I need to delete TikTok, Instagram, or YouTube?
No. LockLeaf is built for people who still want those apps on their phone, but want a better loop around when and how they use them.
What do you actually earn when you complete a quiz?
You earn a short, intentional unlock window. LockLeaf turns extra screen time into something you earn with focus instead of something the feed takes automatically.
Can LockLeaf use flashcards instead of random questions?
Yes. LockLeaf is designed around recall, so your unlock flow can reinforce vocabulary, facts, and study material instead of wasting the interruption.
Who is LockLeaf for?
LockLeaf is for students, creators, founders, and busy professionals who keep bouncing between focused work and reflexive scrolling.
Is LockLeaf privacy-friendly?
LockLeaf is built with a privacy-minded approach and a bias toward collecting as little as possible. For the latest app-specific privacy details, email support@lockleaf.app.

Hi, I'm Thang 👋
I'm a student in Vietnam who loves building tools that actually help people. I noticed how much time we lose to endless scrolling, and how existing app blockers feel like punishment instead of encouragement.
That's why I built LockLeaf — to turn focus into a rewarding game. I believe software should be playful, intuitive, and respectful of your time.
