Have you looked at Evernote? Even the free plan does a lot: - synchronized notes across 2 devices - favourite things you want to be always available on your phone/tablet - search for text in images and PDFs Other plus points: * Plus and Premium plans for more data and devices. * As many notebooks as you like for different subjects * Tags to use in place of or in support of notebooks and document content. Disclosure: my only connection with Evernote is as a satisfied customer.
