Tweny is designed to address eye strain caused by prolonged screen time, which can lead to issues like eye floaters, headaches, and blurry vision. The app was created specifically for people who spend 7+ hours daily staring at screens and want to protect their vision while maintaining productivity.

Key features include Live Activities integration, an Apple Watch app companion, health tips from professionals, and gamification elements like badges, streaks, and 12 levels to complete. The app provides customizable timers that work with the Pomodoro technique while incorporating eye protection measures.

Tweny works by combining the 20-20-20 rule (taking a 20-second break every 20 minutes to look at something 20 feet away) with traditional Pomodoro work intervals. Every work session ends with a proper eye break specifically designed to reduce eye strain and protect vision.

The primary benefit is preventing eye fatigue and maintaining focus while protecting your vision from the effects of prolonged screen exposure. It helps users stay productive while implementing healthy eye care habits throughout their workday.

Target users include anyone who spends significant time working on screens, particularly those experiencing eye strain symptoms. The app integrates with Apple's ecosystem through Live Activities and Apple Watch support.
