Congruent worked in tandem with the partner in building this application. The application is built in typical waterfall model and done completely offshore with quick turnaround.

About the App

HD is an app that will turn an Android tablet into a Kiosk and hence gather electronic information from patients using surveys. HD includes three modules – Blocker, Notification and Survey which work together to get the desired output.

While the Blocker turns the device to a kiosk, the notification acts as bridge between the Android device and HD server in communicating the data back and forth. Survey module launches the survey, when available, to the users for them to fill in their responses to the questions in the survey.

Data thus collected, gets posted onto the HD server directly over Secure Socket layer based communication. The app provisions for multi-lingual support, good and easy navigation for users as the target is people aged 60+ who may not be savvy about the use of tablets.
