The MyCircadianClock app facilitates the participants with all the research work, where they can track their daily food intake, sleep, exercise, blood pressure & body mass index. They can send images with the food name to the server where research coordinator tracks the participants’ daily activities. If the participant doesn’t send any food details to the server then research co-ordinator notifies the participant with a notification. With this app participants can track their daily steps count, height, weight, cycled distance, heart rate which is synced from the google fit app.

Implementing square camera feature was not an easy task because we had to manage the camera preview according to different screen sizes.

Offline data sync feature was another good challenge for us where we had to sync huge amount of data with the server.

Restoring all the data after re installation by the existing user was best way a user can get back all the data.

Managing the different screen sizes to display the chart was exciting for us, giving good experience about managing views.

To get the accurate details from google fit was another challenge for us, which we managed to pull off at the end.
