App Description
Full text searching and flexible viewing of your PDF library
Do you have a collection of PDFs that you never refer to because it's just too hard to find what you're after? Or a collection of PDFs, perhaps covering policies and procedures (as an example) that others don't refer to because they can't find what they're after?
Know It All fixes both of those situations - it provides full text searching and viewing of PDFs in one app! No data is shared with the cloud and the device doesn't require an internet connection, so you can use it anywhere and anytime. In addition, you can create multiple indices, so a huge collection of PDFs can be pre-filtered according to your focus at the time! And there are no ads!
