Solve2Open

Does your child open their phone without limits? Solve2Open blocks any app and only allows access after a math challenge is completed. No subscriptions, no ads, no cloud data.

HOW IT WORKS

Every time someone tries to open a protected app, a math challenge appears on the screen. Only those who solve the problem correctly can access it. If they don't succeed in 10 attempts, they return to the beginning.

Upon completing the challenge, the protected app opens automatically. If the screen is locked while using a protected app, the challenge will be presented again upon unlocking.

CUSTOMIZE IT

- Choose which apps to protect: YouTube, games, browser, or any other

- Select the type of challenge: addition, subtraction, or both

- Adjust the difficulty: 1, 2, or 3-digit operations

- A parental PIN protects all settings so only you can change them

TOTAL PRIVACY

Solve2Open does not collect any personal data, requires no account, and does not connect to external servers. Everything works locally on your device.

It requires enabling the Android Accessibility Service to detect which app is being opened. This permission is used exclusively to intercept the launch of protected apps and does not access passwords, text, or personal data.

WHO IS IT FOR?

- Parents who want to limit their children's screen time on phones and tablets

- Families who need parental controls without paying for subscriptions

- Anyone who wants to reduce compulsive app use
