A little while ago, Microsoft updated its Android OneNote app to allow users to take Handwritten notes. I wanted to play around with it a bit before coming to any conclusions. Having done so, I think OneNote is now one of the leaders if not the leader when it comes to organization.
If you're not familiar with OneNote, it is similar to Evernote in that it allows you to create Notebooks with web clippings, notes, etc. If you have a Onedrive account with Microsoft (free/paid), you can store your notebooks in the web and access them across multiple platforms.
For example, I have various projects that I am working on. I have a OneNote notebook for each project. Inside the notebook I now keep my handwritten notes (either scanned in or, now with the update, taken on my tablet). I can then look at those notes on the computer and add in other notes, annotate PDFs, copy in articles, and much more.
For me, the ability to hand write notes on my tablet directly in to OneNote is an unbelievable gain. It is a shame more people aren't familiar with OneNote and what it offers. If you're in that boat, I highly encourage you to give it a try.
