I think there's a misconception that you need a 'subscription' for the addon IPTV Stalker, but in reality you are getting access to a Stalker middleware that interfaces to NFPS or Rocket iptv servers, which is what you donate for. There are 4 ways to connect to the stalker middleware, through dedicated Set top boxes, through STB emulation, or through 2 different Kodi addons, PVR Stalker or IPTV Stalker. Someone out there integrated IPTVstalker into a custom Kodi build, calling it an App...it isn't necessary, and maybe a scam. Hopefully, Kodi with a stalker addon is all you need, its assumed thatit probably will work, but not completely sure after 15 july, unlike the STBs which is almost certain to work
