This App is for alphaprep internal users(instructors ). They can login to the app and log their session time (billable time) and this will be saved in the server db. Two options are available; one is for individual student billing hours and other one is for class billing hours. If they take a class for an individual student, they can submit those details through this APP by selecting the student and the subject, hours and the description. If they want to submit billing hours for individual student they have to get the student signature - the app has the option so that students can sign there, this signature will be uploaded to the server. In this, the instructor can verify all the submissions. For the class room billing, the user can select the class, where it lists out all the student names for that class. Instructor can mark attendance and submit the billings hours for the same to the central db.
