WritePad Update Link
WritePad is probably the definitive handwriting recognition app for iOS. It’s been updated to version 6. It’s a very capable note taking app. WritePad supports Dropbox syncing and Google Docs access. There is also support for Spanish and French recognition (in app purchase) as well as a user dictionary and shorthand support. There’s really no training necessary although it does allow some minor tweaks to how recognition is performed.
