Notes is the built-in memo taking app for iPhone, iPod touch, and iPad. It debuted with the original iPhone as part of iPhone OS 1.0 and has persisted ever since. As bare-bones an app as they come, Notes eventually added a very few extra features. iPhone 3.0 added copy and paste, and eventually the ability to show replacements and definitions. iOS 4 brought the ability to sync over IMAP. iOS 5 added — thankfully — the ability to change the default font from the original Marker Felt to Chalkboard or the system default Helvetica. Sadly, font changing was lost when Apple updated the look and feel of Notes for iOS 7. With iOS 8, however, a few new features will again be added, namely rich HTML text support similar to Mail — the ability to use bold, italic, and underline, and to insert photos.
Apple added a version of Notes to the Mac with OS X 10.8 Mountain Lion, and Notes are also available and accessible via the web at iCloud.com.
