Hey, Minus, are you guys alright? Because you're demonstrating the developer equivalent of multiple personality disorder. Sixteen months after Dropbox-style cloud storage app Minus shifted 180 degrees to take aim at Instagram, it has once again become a completely different service, this time with a new name. Minus is now "Meow," a randomized chat client, sort of like Omegle or Chatroulette without the video. All that's left of the latest Minus re-brand, or indeed the original storage app, is the "com.minus.android" APK name.
One of the great things about Android's ecosystem is the number of indie developers who are able to enter the market successfully, providing a great product and inspiring would-be developers to join in. For many though, Android development in general is a mysterious topic. How an app or game goes from an idea to an entry in the Play Store is unknown, but (thankfully) not unknowable.
Of course, considering how major development studios bring apps to life doesn't require too much thought – major companies like EA, Disney, or Rockstar have no problem hiring designers and developers to crank out and maintain polished apps.
