During those three years, they took over and completely rewrote our iOS and Android apps, and added many significant new features.  They learned Android development during working for us, and became a fabulous one-stop mobile software development shop. They’re amazingly independent and responsive, and need very little direction.  Literally, I ask them to implement something on both platforms, and they do it. Thanks, guys!”
