Hi Product Hunt! 👋
I'm Gen, an indie developer. I built Zzzappy because I was diagnosed with early-stage tendinitis AND dry eyes — both from coding 10+ hours a day.
I looked for a tool that could remind me to rest my eyes AND monitor my arm/wrist strain. Nothing existed. Every break reminder app only tracks time, not your actual input load.
So I built Zzzappy. It monitors 5 dimensions of keyboard/mouse/trackpad usage in real-time and calculates a fatigue score. When any metric hits your threshold, it reminds you to take a break.
The smart pause feature was born from frustration — I hated getting break reminders during Zoom calls. Zzzappy detects meetings, videos, calendar events, and custom focus apps, and pauses automatically.
One thing I'm proud of: the break experience. Instead of a boring gray screen, you get a beautiful frosted glass overlay with film grain and ambient lighting. It makes taking a break feel rewarding, not punishing.
