The problem I have with phone or tablet-based applications is that the quality of the mic is unknown and therefore deficiencies in the frequency response of the mic are not accounted for in the measurement. Do your speakers have a big droop at 7 kHz or does the mic in your phone??
In REW using UMIK-1, the quality is known and a specific calibration file for the mic is accounted for in the software and, therefore, the measurement results.
I use and recommend REW.
