Develop an Android App for Internal Communications

QuarkMe is a marketing startup based out of Delhi NCR, focusing mainly on organizing and targeting local crowds for brands with our BTL/offline marketing activation and conversion Campaigns. Our team of Promoters physically reach out to the end-user, give a product demo, explain the functionality and convert the potential lead into an active user of the product. The promoter then has to feed this information back to the management team, and the management team compiles and organizes this data to be shared with the client at the end of an activity. We're currently using Google Sheets to collect, store and organize this data and we want to develop an Android app that will be shared with our team (with different access levels). The key-functions of the app would be: - Maintain a user database on three access levels: Admin, Supervisor, Promoter. - Create and assign tasks and tickets - Execute the task(s) on a ticket (data collection) - Validate the task - Store and sort this data - Generate relevant reports This app will be used primarily for internal communications within the organization. Hence, the app has to be secure enough to preserve the confidentiality of the data being collected.
