What are your favorite productivity apps that you use everyday?

I am trying to find the app for whatever task I do at given time of the day. I use Evernote (for note taking), Omnifocus (for tasks, calendar, reminders), Google Maps (for navigation), WhatsApp (for calls, chats), Apple Mail (for emails), TripIt (for trip planning), UBER (for commutation), Apple Music (for music), Mendeley (for research), Google Photos (for storage, gallery), Spotify (for Podcast), and Apple Notes (for grocery shopping). I am trying to find a good app for grading (assignment, and exam), taking attendance, password management, and budgeting. Any suggestions?
