Hi Product Hunt! 👋 I built OnlineTimeZone because I was tired of opening a phone app just to set a 10-minute focus timer — or dealing with ad-bloated browser clocks that feel like they were designed in 2009. So I built the tool I actually wanted to use. What makes it different: ⚡ Instant & lightweight — Pure HTML/CSS/JS, no framework, no database. Loads in under a second. 🔌 Works offline — Alarms are synthesized using the Web Audio API directly in your browser. Your Wi-Fi can die and your alarm still rings. 🎨 Actually nice to look at — Dark glassmorphism UI with light mode, animated backgrounds, and smooth transitions. Time tools don't have to be ugly. 🛠️ Everything in one place — Alarm clock, countdown timer, stopwatch with lap tracking, world clock, timezone converter, age calculator, date calculator, and hours calculator. All completely free. No login. No ads. No app download. I'm a solo builder and would genuinely love your honest feedback — especially on what tools you wish existed that don't yet. 👉 Try it at onlinetimezone.com
