Spacetime locates a contact on a map by texting them a link to click on

I find myself often texting people, "where are you?" so I wrote this little iPhone app that lets me text them a special link.

What do you think?

In plain words

Spacetime is an iPhone app that helps users locate contacts by sending them a text message with a special link. When recipients click the link, the app uses HTML5 geolocation to determine their location and displays it on a map. The app's accuracy depends on the capabilities of the HTML5 geolocation API. It is designed for anyone who frequently needs to know where friends or contacts are located.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
