  • React Ecosystem
    Integration with the React ecosystem provides access to numerous libraries and tools, allowing developers to use familiar technologies and streamline the development process.
  • Ionic Components
    Leverages Ionic's UI components that are designed to look and feel native on both iOS and Android, providing a consistent and polished user experience across platforms.
  • Live Reloading
    Features like live reloading and hot module replacement can speed up the development process by allowing developers to see changes in real-time.

    Being part of the larger React and Ionic communities, developers can tap into extensive community support and resources to help solve issues and improve their applications.

Possible disadvantages

  • Performance Overhead
    Applications built with React-Ionic may experience performance overhead compared to fully native apps, which can be a concern for performance-intensive applications.
  • Learning Curve
    Developers new to the ecosystem might face a learning curve due to the combination of React and Ionic concepts and components.
  • Platform-Specific Customization
    While React-Ionic provides cross-platform functionality, achieving platform-specific look and feel or leveraging native features can require additional customization and work.
  • Ecosystem Dependence
    Reliance on both the Ionic framework and React means developers must stay current with updates and changes in both ecosystems, which can cause maintenance challenges.
  • Bundle Size
    The inclusion of both React and Ionic libraries can lead to larger application bundle sizes, which might impact load times and performance on lower-end devices.

Questions & Answers

As answered by people managing Scroll Brake and React-Ionic.

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.
