Client reviews Ivan, Impulzity "Impressed on the detail quality not only on the functional side, but also on the visuals! Besides, transparent and direct in communication and results. Well done, any time again!" Mike Lanza, Streetography “Streetography employed Bee Wise as its mobile app developers from 2016 to 2019.  It’s been a wonderful relationship, and Bee Wise has performed extremely well. 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!”
