Cross-Platform Focus App Development

I'm looking for a developer to create a focus/flow state app for both Windows and Mac. The primary purpose of this app is to improve productivity by blocking distractions. Essential Features: - Distraction Blocking: The app should block all distractions except for those that the user explicitly allows. This includes social media sites, unwanted notifications, and certain websites and applications. Ideal Skills and Experience: - Experience in developing cross-platform applications, specifically for Windows and Mac. - Strong understanding of productivity tools and user needs. - Proficiency in implementing effective distraction-blocking mechanisms. - UI/UX design skills to create an intuitive and user-friendly interface.
