Works on the ipad gen 1!!!

Doodle jump fan

This was the only pdf annotator I could find that still works on my old ipad gen 1 - thank you!!! I am doing loads of readings for uni and wanted to try and go paperless. I tried the kindle app but found that not all files could be annotated on that. This one does! It's easy to transfer files and keep them organised in folders. On the odd occassion I can't annotate by highlighting in a particular file, I can still draw on and make notes. It does crash a fair bit, but so does EVERYTHING else on this ipad gen 1.

Brilliant otherwise, except for protected files


I bought this app to be able to place annotations on a protected document. This particular document was viewable on other readers but annotations could not be saved on them. This app crashed every time I tried to open this particular pdf. I am quite annoyed but it is quite useful otherwise.

Great but...


Need more colour selection options for drawing lines and shapes, I'm constantly flicking through several colours and not all fit on pre selected colours line.
