Mobile devices are characterized by attractive advantages, and provide broad benefits in the university students’ math teaching. Our study proposes integrating the Mobile Applications in teaching geometry. Findings of the researches showed that students face difficulties in learning geometry. The material and virtual maneuvers may assist the university students in learning and understanding geometry easily. In this research, we investigated the effects of Mobile Applications (GeoGebra and Sketchpad) on the Students’ Achievement. In this concern, we prepared the educational materials, achievement exams and worksheets according to the university curriculum. And they were applied on the students. This quasi-experimental study was applied on 105 students. The results showed that the use of Sketchpad and GeoGebra facilitated the students’ understanding of the geometry concepts. Furthermore, the results showed that GeoGebra had more effect than Sketchpad on the students’ learning.
