Startup Idea: Android Cloud-based Note Organization App

Startup idea to develop an Android-based note organizing app. That would allow college students to easily scan, store notes on a cloud, and search them using OCR. The app should also let users add reminders, categorize notes, sync with their laptops, and integrate with a calendar. The app could also be expanded to save receipts and function as a planner.

I am currently a college student, and am close to graduation.

I usually find it tough to keep track of my notes and the like as they fly all over the place. I wish I could easily scan my notes into my android and store them on a cloud somewhere, preferably combined with OCR. OneNote comes close, but is quite messy to use at times, making me more disorganized. Preferred features would be adding in reminders to submission based scans, categorization, and if possible, synchronization to my laptop. I have mainly tried OneNote and EverNote, but they get very cluttered, and I have to insert pictures separately, which can get annoying. Finally, it would be nice to be able to link it heavily with a calendar, etc. In fact I could see such an application being used to save receipts, becoming a planner, etc. Those issues drove me off OneNote, and EverNote.
