needs for everyone, especially students and teachers during
online learning. These devices provide helps in searching for
unlimited learning resources. However, there are only few

this problem, it is important to study and develop mobile
application-based media to improve students’ competence. The
product was developed using the ADDIE model and was tested
on students and teachers at a vocational school in Yogyakarta.
The results indicate that Android-based mobile media is very
feasible. The empirical testing result also shows that the
developed product can promote 21st century’s competence.
