  The main aim of the proposed system is to assist the software development
team to estimate the cost, effort and maintenance of the project under
development. Android-based platform, namely MIT App Inventor is used for the
development of application, which contains visual block programming language.
The current study has following uniqueness of (1)Accuracy of results,(2)user
friendly environment(3)no such application is available on android platform to
the best of our knowledge. Questionnaire regarding CoCoMo model is developed
and circulated by using objective qualitative method. Findings: The estimation
module of our application is quite important with respect to facilitating the
students of software engineering for performing CoCoMo-based cost estimation
easily, and enabling the software developers for performing software cost
estimation easily. The cost estimator based on CoCoMo model is developed on
android platform however, to the best of our knowledge no such application is
available. This system can be used by business and educational stakeholders,
such as students, software developers, and business organizations
