Huan Truong, a software developer, writes in a blog post: There is always an unlikely app that consistently works on all of my devices, regardless of their OS and how old they are: Google Maps. Google Maps still works today on Android 1.0, the earliest version available (Maps actually still works with some of the beta versions before that). I believe Maps was only a prototype app in Android 1.0. If I recall correctly, Google didn't have any official real device to run Android 1.0. That was back all the way in 2007. But then, you say, Android is Google's OS for Pete's sake. How about iOS? Google Maps for iOS, version 1.0, released late 2012, still works just fine. That was the first version of Google Maps ever released as a standalone app after Apple ditched Google's map solution on iOS. But wait... there is more. There is native iOS Maps on iOS 6, which was released in early 2012, and it still works. But that's only 6 years ago. Let's go hardcore. How about Google Maps on Java phones (the dumb bricks that run Java "midlets" or whatever the ancient Greeks call it)? It works too. [...] The Palm OS didn't even have screenshot functionality. But lo and behold, Google Maps worked.
