Hey Product Hunt! 👋 I'm thrilled to introduce FlowFlip (https://flowflip-seven.vercel.app)! Like many makers, I spend hours coding and writing in my browser. But whenever I tried using standard digital countdown timers, they either felt clinical and boring or were cluttered with annoying ads and monthly subscriptions. I wanted something tactile, aesthetic, and satisfying to leave open on my second monitor. Inspired by vintage Solari railway split-flap boards, I built FlowFlip: ⏱️ Physical Split-Flap Kinematics: Realistic 3D card flipping that gives time a tangible physical weight. 🎧 Tactile Audio Feedback: Mechanical click sounds synthesized with Web Audio API, plus ambient rain, cafe, and white noise. 🖥️ Distraction-Free Zen Mode: Fullscreen mode designed to sit on your desk or secondary screen without notification clutter. 🎨 16 Deep Work Themes: From vintage warm Solari and Monokai to Midnight OLED and Cyberpunk. 🌍 Fair Global Pricing: No recurring subscriptions. Just a one-time lifetime pass with Purchasing Power Parity (PPP) built-in. FlowFlip is 100% free to use in your browser right now—no signup required to start a session. I’d love to hear your feedback: 1. How does the card flip animation feel on your screen? 2. What other soundscapes or themes would you like added? Thank you so much for checking it out! 🚀
