pretty sure that it only supports certain systems

It supports Android and Windows, supposedly it only works on 64-bit OSes but it seems to work fine on my 32-bit PC, but the app never fully installs on my Android phone [ my phone is an LG K51 ]. All Android phones [ Samsung, Motorola, LG, etc ] all run on the same OS, so no, it doesn't just work on certain systems.
