PDF Compress not Working and PDF OCR only Average

I want this to be a great quality app but it is not there yet. My first interest was PDF compression, but this did not work at all for me. The "compressed" files (low, medium, high) all came out as the exact same size as the inout PDF.

The OCR feature is no better than average. I ran the OCR process on a PDF created from Kindle Reader screen shots - very clean input text - but the OCR output had 5-6 word recognition errors on every page.

Come on Developers I know you can do better than this!

Poor value, no novel features

I gave this a try in comparison to PDF Expert and PDF Element. There is nothing novel about this app, and it has several deficiencies.

1. It requires a subscription but provides no more functionality than other less costly apps. PDF Expert, for example, is almost 70% cheaper and does more.

2. It cannot create and edit forms. If this app could create and edit forms as well or better than PDF Element or the even more expensive Adobe software, it would have some competitive advantage. As it stands, I have investigated the feature set and don’t see how it is differentiated from other options.

Also, it seems odd that dark mode and cloud storage are two of the five features highlighted on the app store. Those are of marginal interest or novelty in a PDF app. The free Apple Preview has dark mode and cloud storage, for example.

I don’t see the value proposition here.

Developer Response ,
