4sqwifi — find nearby venues w/ wifi & their password

Hi HN, I want to show you my first iPhone app. It's called 4sqwifi. I use Foursquare to find nearby venues with wifi and their passwords. We (me and a friend of mine who helped with coding) used Titanium Appcelerator to develop the app. The way it works is that we have a nice little algorithm communicating with Foursquare's API and then brings back the results which are only nearby venues with wifi -- and their passwords as tips. I think it's an interesting way to use Foursquare, right between social location awareness and everyday life-hacks. If you have any feedback, it's greatly…

In plain words

4sqwifi is an iPhone app that helps users find nearby venues with wireless internet access. Using Foursquare's API, the app locates neighboring locations that offer wifi and displays their passwords, which are crowdsourced as tips within Foursquare. Built with Titanium Appcelerator, it bridges social location awareness with practical everyday utility by combining venue discovery with network connectivity information.

    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…
