Is there a user manual?

I have PDF Pen on my desktop and thought the Nitro app might be useful on a tablet. However, the iPad OS app works differently than the desktop and I can’t find a user manual for it. Is there one?

Also, I am mostly interested in OCR and conversion to text documents. It seems like tablets these days have enough power to do that, so will these functions be included? Or are they already included but I don’t know how to find them??

Not all functionality available. No product support

Some of the functionality does not seem to be available on the (paid for app) - cant rearrange or rotate pages. Cant add to the library. Functions are visible but greyed out. There is no product support for the iOS app (only the desktop version) - if there is support I could not locate it. I opened a ticket and posted these issues on the community forum without any success. There are no dedicated iOS product areas. The user guides are hard to locate and only relate to the old PDF pen product. The app doesn’t cost much for a pdf editor but it’s still not worth the money.

Superior PDF handling, & economical

I purchased it for my Macs, and use the free Reader (which has considerable editing functions, including flattening) on my one Windows machine. Greatly satisfactory in both environments.
