Windows 8 apps: OneNote MX
Microsoft’s excellent freeform notetaking app makes it easy to build documents from photos, (handwritten or typed) text notes, pictures, drawings, audio files and more.
The ability to tag items on the page adds a little flexibility. Add “To Do” tags, say, and your items will gain checkboxes that you can click when they’re complete. You can create multiple notebooks, each with as many pages as you need, then save them to the cloud for access from any of your devices (or perhaps to collaborate on with others).
And of course the program works with Windows 8 Search, making it easy to find the note you need. Even if it was written on a PC, and you’re now on your mobile device.
