TSAwait
TSAwait almost made the FAAwait naming scheme make sense. It let you see TSA checkpoint wait times at airports all across the country. But then the TSA for some reason decided to stop sharing this information with the world, and this precious app was left to plod along with data that grew more and more outdated. So it was finally sent to that great queue in the sky to live out its life in early-iOS design glory.
Along with it went the (undepicted) TSAwait Lite, a companion app that offered some of the functionality with none of the (admittedly minimal) price of the "full" app. Yes, there was a whole brand strategy of sorts there. But the TSA had other plans.
Thunder and Lightning
(Version 1.0)
Sure, this app started as a bit of a joke. And as an app it was entirely a one-trick pony (to try to estimate how far away you were from a sound source). It had a horrible first-generation-iPhone UI that was never updated for any of the iOS releases (or devices) that followed. It was left on the store because it was free and a lot of people downloaded it, and year after year it just continued to work. It was a bit of an experiment as to how long some of that classic code could survive on newer and newer hardware and software. Those days seemed to be coming to an end, and the time was nearing to pull it from the store and put it out of everyone's misery. But then we did the right thing and updated it a bit, after a mere eight years.
