If you spend 7+ hours a day staring at screens, your eyes are paying the price. Eye floaters. Headaches. Blurry vision. I built Tweny because I was tired of my own eye strain. Tweny is the first focus timer that combines the 20-20-20 rule with Pomodoro. Every work interval ends with a proper eye break. You stay productive AND protect your vision.

XcodeDevelop, test, and distribute apps for all Apple platforms

I used Xcode for the entire development of Tweny. It handles everything from writing SwiftUI code to designing the Apple Watch app, building widgets, and testing Live Activities. The integrated simulator lets me test on different iPhone and Watch models without needing physical devices for every case. Instruments helped me optimize performance and catch memory issues early. For native Apple development, there is really no alternative.

I chose GitHub because it keeps everything organized and safe. All the code, version history, and project files live in one place. I can track every change I make, roll back if something breaks, and keep a clean record of how the app evolved over time. For a solo developer, having that safety net is essential. It just works and I never have to worry about losing progress.

Claude by AnthropicA family of foundational AI models

I used Claude throughout the development process as a coding assistant and thought partner. It helped me debug tricky SwiftUI issues, refactor complex logic, write cleaner code, and think through architecture decisions. When I got stuck on something like Live Activity state management or WatchConnectivity sync problems, Claude helped me understand the issue and find solutions faster. It also helped with copywriting, from onboarding text to App Store descriptions. Having an AI that understands context and writes quality code made the whole project move much faster.
