Show HN: Windo, a Simple Timezone Tool

I created the timezone tool I have always wanted. Something simple, useful and shareable.

The application is URL based and saves to your browser's storage so you don't have to keep adding/removing timezones to compare.

Additionally, I wanted each URL to be shareable across many platforms. Windo parses each URL to generate dynamic open graph images and titles that unfurl when you post that link to different platforms.

There is a lot I still want to do, but I was curious if this is something you all would use and why?

Thanks a ton!

...But then all of the suggestions for cities to add were "close" timezones. I naturally can quickly infer when California or New York time is, so once I've selected that I'm in Chicago, a pile of suggestions for n-2 and n+2 cities isn't all that helpful.

If I pick a US-based initial timezone, offer me London, Tokyo, etc. Like, suggest timezones that I probably can't easily calculate from memory, and am likely to be interested in based on popularity in international business.

Only thing is it has a limited set of free features.
