Prevent app read the database (presence app)

I need an app to record my students’ attendance online. I have about 380 students and they must report their attendance twice a day. Therefore, there will be 760 new data a day.
Unfortunately, the app always read the result database and show it at the front page.
For some old phones, it makes them lag to do the job because of the big database.

Is there any way to prevent the app to read the result database?
I need to make it write only without reading the database.
Thanks in advance.

Perhaps this will help that:
