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.
