There is a significant segment of the "hard hat" market that needs project based mobile apps. These apps must be quick and easy to develop as they may only be used for three months on a particular project. The ROI needs to be a matter of days, not years. During those three months, however, project management and the profitability of the project could realize great benefits from having real-time data collection, reporting and collaboration via mobile devices.
I think a project-based mobile app may need to include a quick data collection and reporting template that is pre-integrated with a database and reporting tool. Otherwise, the integration and report generation work might take longer than the project.
