I think this has a ton of useful features, but it fails at the most basic level of PDF use - reading. PDF at its heart is a document and documents need to be read. Panning and zooming controls work different than every other viewer and are inconsistent, making reading on a small phone screen difficult. Portrait mode has so much wasted space - nearly 2/3rds of the screen is taken up by UI elements that are themselves too large and space hogs for no reason, leaving about 6 lines of text visible.

Thanks for the detailed feedback. We agree that the controls take up too much space while reading PDFs in portrait mode. We're working on improving the reading experience by allowing the controls to automatically hide while reading, giving the document more screen space. We appreciate you pointing this out.

Great pdf application. Has most of the tools and is ad-free!! Just a few bugs in the UI, like the cross button sometimes goes at top corner of the screen in the status bar, so you can't click on it. And image-pdf would be better if you could see preview of the images and reorder freely, even better if it could rotate images automatically to match correct orientation, yk sometimes you have a potrait image in landscape orientation. And a search bar for pdf tools will be great too 😁

Thank you for the detailed feedback and suggestions! We're glad you're enjoying the app and its ad-free experience. We'll look into the UI issue with the close button, and we appreciate your ideas for image previews, easier reordering, automatic image orientation correction, and a tool search feature.

The image scanning option isn't very reliable. Other apps have dedicated windows for scanning the image. I suggest to improve the scanning of images. Currently the app fails to scan images properly; like when I was trying to scan multiple images at once, some pages were not scanned, some complete white and some turned sideways.

Thank you for the detailed feedback. We're sorry to hear about the issues with image scanning. Improving scan reliability, page detection, orientation handling, and multi-page scanning performance is a priority for us. Your suggestions are valuable and will help guide future improvements to the scanning experience.
