Customer Reviews


Crashes quite often, probably once every 3-5 times I use it. I still use this app because I have yet to find another free app that allows tabbed PDFs along with annotations.

needs more features

to make this app better, please consider:
1. add horizontal scroll (when zoomed in > 100%)
2. ability to add text box annotation
3. just put all annotations on menu bar, instead of “more annotation tools”. as so far there are only ~5 icons

if these three features were added in next release, i will modify to 4 star (at least)

Full Screen is broken

I enjoyed the simplicity of Mighty PDF until I attempted to view a pdf in full screen mode on my second monitor. MightyPDF acts like it wants to be on Mountain Lion (10.8) so it gives me a big grey screen. Unforunately, it’s in Mavericks, so the actual pdf is nowhere. Three stars is generous but fair, I think, considering this app does what I’ve wanted other to do without nagging me for something: tabbed pdf viewing.
