## What is Math Shield?

Stay Focused with Math Shield

Math Shield helps you reduce distractions and build better focus habits by placing a math challenge between you and your most distracting apps.

Instead of mindlessly opening social media, games, or other time-wasting apps, you'll need to solve a math problem before gaining temporary access. This simple barrier helps break automatic habits and encourages intentional screen time.

Key Features

Block Distracting Apps: Choose the apps you want to limit and keep them locked during focus sessions.

Unlock with Math Challenges: Solve math problems before accessing blocked apps.

Temporary App Access: Gain limited access after successfully completing a challenge.

Stay Productive: Create friction between impulses and distractions to help maintain focus.

Easy Setup: Select apps, choose your preferences, and let Math Shield help you stay on track.

Perfect For
- Students who want to focus on studying
- Professionals who need distraction-free work sessions
- Anyone looking to reduce screen time
- People building healthier digital habits

Whether you're studying, working, reading, or spending time with family, Math Shield helps you take control of your attention—one challenge at a time.

Download Math Shield and make every app unlock a conscious decision.
