Approximationist: The Friendly World Clock for Humans Approximationist is a world clock app for people who don’t want to do timezone gymnastics before coffee. It helps you quickly understand what time it is around the world, with a fun approximation-first approach that answers the only question that matters: “Is now a good time?” Now with time slider, export/import and share of the teams' info (as sets) Need to coordinate New York, London, and Tokyo? Approximationist lets you compare cities at a glance and translate your local time into theirs without melting your brain. What makes it different World clock, but chill: Track multiple cities and time zones in one clean view. Approximation that helps: See rough equivalents fast when exact minutes aren’t the point. Quick overlap spotting: Find windows when everyone is probably awake and responsive. Human-friendly timing: Think in “early morning,” “around lunch,” or “late evening,” not just raw offsets. Less math, more momentum: Spend less time converting, more time actually scheduling. Perfect for Remote teams spread across time zones Freelancers working with global clients Travelers planning across regions Friends and families who live far apart Anyone who has ever asked, “Wait… what time is it there again?” Approximationist keeps global time coordination simple, useful, and a little more fun. Because life is complicated enough without manually adding 9 hours in your head. Friendly disclaimer: Approximationist is made for quick, practical time estimates, not split-second precision. If you need exact precision, there are many beautiful apps on the App Store, please take a look at them. Introductory pricing note: Approximationist is currently available at a special launch price for early users.
