Questions & Answers

As answered by people managing Sharp World Clock and ZoneMap.

Which are the primary technologies used for building your product?

ZoneMap's answer:

Typescript, Vite, React, Hono, Framer Motion.

How would you describe the primary audience of your product?

ZoneMap's answer:

Remote workers and distributed teams are the core audience: engineers, managers, and freelancers who work across multiple timezones daily and need to quickly find meeting windows. Secondary audiences include international travelers checking destination times, digital nomads coordinating with clients across the globe, and curious people who simply want to see what time it is around the world with a beautiful day/night visualization.

What makes your product unique?

ZoneMap's answer:

ZoneMap is the only free world clock that combines a live day/night terminator map with a multi-city time comparison view in one interface. While most timezone tools show you a list of clocks or a static map, ZoneMap renders an astronomically accurate solar boundary on an interactive world map in real-time, you can instantly see which cities are in daylight and which are in darkness. You can also drag the timeline to scrub through any time of day and watch the terminator shift across the globe. It supports searching 33,000+ cities (powered by GeoNames), far more than alternatives that typically cover only a few hundred. And everything is shareable via URL. No account, no ads, no friction.

Why should a person choose your product over its competitors?

ZoneMap's answer:

  • Visual clarity: Competitors like WorldTimeBuddy show time as rows of numbers. ZoneMap shows time spatially on a map with a live day/night overlay, making it intuitive at a glance.
  • Zero friction: No sign-up, no ads, no popups. Open the link, add your cities, done. Your configuration persists in the URL so you can bookmark or share it. 33,000+ cities: Most competitors support a few hundred cities. ZoneMap's GeoNames-powered search covers virtually every named place on Earth.
  • Working hours overlap: A visual bar instantly highlights when business hours overlap between your selected cities — perfect for scheduling across timezones.
  • Time scrubbing: Drag a slider to any time and see all city clocks update simultaneously, plus the day/night boundary shifts on the map. No competitor makes "what time will it be everywhere at 3pm my time?" this visual.
  • Completely free and open-source (MIT license).

What's the story behind your product?

ZoneMap's answer:

ZoneMap was born from the frustration of juggling timezones in a distributed team. Existing tools were either cluttered with ads (timeanddate.com), limited to a handful of cities (Every Time Zone), or lacked a visual map entirely (WorldTimeBuddy). I wanted something that answered "what time is it for my team right now?" in one glance, a live map showing day and night, with city clocks overlaid, and the ability to scrub forward to find meeting times. So I built it as a weekend project, open-sourced it, and launched it on Product Hunt and Hacker News. It now serves users worldwide, entirely free with no accounts or ads.
