Purpose and Motivation: The rapid progress in mobile applications and the highly competitive environment increase the number of mobile application projects. Problem Statement: The purpose of the study is to find an appropriate approach that meets the requirement of mobile application systems. Methods: We will study agile processes to meet the requirements, making mobile application development simple and well-suited wit the characteristics of mobile devices. It was discovered that agile methodologies are best suited to the development of mobile applications as they are small time, need suppleness reduces misuse and promotion of time. Results: We have studied several agile approaches, but no research provides specific reasons to adopt Agile as necessary model for development of mobile applications. Conclusion: For mobile application development, we have proposed the modified Agile methodology that would the best Agile approach and that meets the strengths of each selected approach for mobile software engineering and removing the weakness. ©2019 IEEE.
