I tried Evernote and was not impressed. I'm vision-impaired and the mobile version was not user friendly for me. It's unfortunate since I could see its potential. I have the same complaint about Quora. I've tried Microsoft's OneNote. It was much better, but it took forever to open. Hardly surprising since Microsoft made it.

I've been using a Notebooks app on my iPad that syncs to Dropbox but is no longer in the Apple AppStore, so it's life is limited. I'm open to other options that allow for a nested folder structure and the ability to increase font size for the notes and for the interface itself.

You mentioned Nimbus and Notion. Can you tell me if either is any good for a vision-impaired user? Also, can either be synced across both an Android and Apple?
