Abilipad app, formerly Intellipad app, has a new logo and continues to be updated and expand supports for struggling writers on the iPad. Available for iPad only (19.99), it is the only adaptive note taking app I am aware of.
The ability to add pictures to the note pad also provides additional visual prompts and supports for users during the writing process.
Here is one of two instructional videos about Abilipad app from the Abilipad developers website:
This is a great tool for special needs and is currently a one of a kind and worth the cost for its unique visual and adaptive supports providing word prediction and text to speech tools for writing.
