Yes, I've been actively using PDF Guru
https://guardian.ng/technology/tech/pdf-guru/ for some time now, and I can confidently say it's a truly excellent tool for working with PDF files. I myself spent a long time searching for a convenient solution, as there are too many apps on the market, and often the functionality is limited or the interface is confusing. PDF Guru pleasantly surprised me with its simplicity and power: editing text and images directly in PDFs is seamless, working with forms and signatures is intuitive. And merging and splitting documents takes literally seconds.
