The result of field test shows that there are some statement items that are in valid criteria with value of Factor Factor> 0, 5. Aspects with valid statement items include Preparation stages with 5 statements and Alpha Cronbach values ​​obtained at 0.640, Learning Activity stages with 23 statements and Alpha Cronbach values ​​obtained by 0.962, and Closing stages with 4 statements and Alpha Cronbach values ​​obtained at 0.680.  Based on the results of the study, it was found that supervisors and teachers were very appreciative with the instrument of android based clinical supervision and the supervisor felt easier to conduct clinical supervision activities to the subject teachers.
