On Android you actually have something better than Filmic Pro, you can use something called MotionCam [Pro], which allows you to record RAW video, or optionally ProRes or HEVC (still in beta/alpha right now) in various log formats. There's also mcpro24fps for a slightly more traditional video app (free in Russian language). Between these, the video recording situation appears to be signficantly ahead of iOS even without Filmic Pro.
