The actual EFB just shows takeoff speeds in non limited runways. In the real EFB you can input all the conditions to get a RTOW (Restricted Takeoff Weight) as this plane most of the time operates in limited runways (High Altitude Airports, extreme weather, short runways). This changes a lot the takeoff speeds and specially limits the TOW.
Check the real takeoff calculator from ATR. Its a free app although databases needs to be updated.
