says: I use my phone to jot down notes when I don't have pen and paper handy. Depending on what I'm doing I'll reach for a particular app. If I'm looking for a simple interface that I can dump my thoughts into without having to sync with the cloud, I'll go with AK Notepad. If I want to be able to access a note or photo anywhere, I'll go with Evernote. If I want to keep track of my todos and appointments and have it automatically update my calendar and sync to the cloud, I'll use Astrid. I'm I'm brainstorming and want to do a little mind mapping I'll use Thinking Space. If I want to share my notes with others efficiently and read and create QR codes, I'll use 3bananna Notes.
