The app works surprisingly well, even tracking with my Galaxy Note 8. The build quality is amazing because it looks like you're using professional camera accessories that you can buy at B&H. A good suitcase is also included. Filmic Pro doesn't work, but that doesn't matter because when you start capturing video, you probably only have control over the focus and can control it on the display. But I had to go back because Vilma M didn't balance my Galaxy Note 8 even without a case. For small phone users, I highly recommend it, but for Galaxy Note users, you have no choice for Vilma M.
