Questions & Answers

As answered by people managing AppBlock and Scroll Brake.

What's the story behind your product?

Scroll Brake's answer:

We noticed that standard app blockers fail in two ways: strict hard blocks force users to delete the blocker during an urgent message, while passive 5-second delays become invisible to muscle memory. Escalating mental math creates the exact cognitive pause needed to close the app voluntarily.

Which are the primary technologies used for building your product?

Scroll Brake's answer:

Native Swift, SwiftUI, Apple FamilyControls / ManagedSettings / DeviceActivity frameworks on iOS, and TypeScript / Manifest V3 for the Chrome Extension.

What makes your product unique?

Scroll Brake's answer:

Instead of passive countdown timers or breathing animations that muscle memory learns to ignore within days, Scroll Brake uses active cognitive friction — requiring you to solve adaptive mental math puzzles (with escalating daily difficulty) before distracting apps or websites open.

Why should a person choose your product over its competitors?

Scroll Brake's answer:

  • Cognitive System 2 Interruption: Arithmetic challenges break automatic dopamine scrolling loops.
  • 100% On-Device Privacy: Built on Apple Screen Time API (FamilyControls) and Chrome Manifest V3 with zero cloud servers and zero browsing logs.
  • No $99/Year Subscriptions: Generous Free Forever tier (up to 3 active limits covering unlimited apps) + optional $29.99 one-time Lifetime unlock.

How would you describe the primary audience of your product?

Scroll Brake's answer:

Developers, students, founders, and knowledge workers with ADHD or high screen exposure who want to stop compulsive doomscrolling on iPhone and Chrome without surrendering their privacy or paying $100/year.
