Notability is good to write in & has some excellent features - BUT - trying to read notes becomes an issue - there is no way to turn off the controls & simply read or revise notes - this is a big issue for me & I have contacted the developers who have advised that they will take it into consideration for future updates - which is great but - for the moment, it's far too distracting when trying to read my notes.
Besides trailing Springpad - which I already posted about - I am leaning more & more toward simply using Pages & then setting up folders in Readdle Docs for file management & search capabilities - Pages allows for great composition when adding pictures, has good font choices etc although it's obviously a no-go for handwriting.
For basic handwriting together with audio - audio note is pretty good & has a free lite version but for a combination app - handwriting, text, web clips, audio recording, graphics/photos etc with excellent handwriting capabilities - Whitenote is an impressive app- the UI isn't too pretty but it has email & Dropbox capabilities & you can also paste PDF's into a notebook - the 'notebook' motif is also useful & has possibilities for different books for different uses - eg lecture notes, meetings, assignments etc ... It's definitely worth a look if looking for a complete multi-capable app - audio is not as good as with dedicated audio recording apps such as Audio Memos - the paid version of audio memos allows for background recording however so this is yet another way to go? Audio Note has good recording plus text and handwriting and will highlight text during playback - very handy.
I have tried a variety of different note systems and I am beginning to think that there isn't one app that can meet all my needs all the time - at the moment I am dedicating different apps to different needs - eg meetings require audio so I use audio note or audio memos - if I want straightforward notes with some graphics then Pages is clean and pretty - more complex stuff - such as lecture design I use Whitenote. & writing assignments based on PDF's I will use Noterize as I can annotate plus add entire pages to my PDF's - file management is through Readdle/Dropbox as mentioned so that although I create documents in different apps, I store them in relational folders that make sense to me & ensure they are available through both iTunes to transfer onto my computer and/or Dropbox for both desktop access and access to my stuff if at a work computer ....
Apologies for the long post & if I have repeated apps mentioned elsewhere ... It's a subject I am passionate about- I spend a lot of time testing these apps as note taking/document creation & VGA output of said documents in class are the main reasons I bought my iPad.
