If you are flashing the BMS file to use as a backend flash (bef) then mhd with the flasher module is all you need. You are correct in assuming the jb4 mobile app is sufficient for monitoring your car.

Currently, MHD flasher is better than the BB flasher. The BB flasher is under redevelopment/upgrade and because it's free, could be worth keeping in your case. I have not kept up with the updates but you could research here and on bimmerboost for more information or to help test the new flasher.
