The problem QuickAttend solves

The aim of the project is to ease the task of recording attendance for teachers and helping students to check their attendance
without involving the teacher.

Challenges we ran into

1)The first and major problem was that we needed an online database, which can filter out Students' and teachers Data at a different level and that was possible with the help of Firebase's firestore database.
2)The second problem was we didn't want our application to be limited to the online database only. So we decided to provide the functionality to convert Attendance data in an excel sheet also and that made the bug that we faced were very tiring as we only thought about it and didn't have any experience on how to do it. So we googled it ran into few APIs got some bugs, tried to solve it got some more bugs, contacted the developer, and tried his solution, and after too many hits and trial we finally did it.
