What is the point of offering a trial if you can’t even demo the product? It would be fine if they include a watermark or prevent export files, but this is just a complete waste of time. They can’t even figure out how to make a demo - doesn’t bode well for the paid version. The search for an Acrobat alternative continues. ### 1/5 — Shame on this development team and developer *2025-05-30, version 1.7.0* I purchased the Pro version and I didn’t received the pro version trash app ### 1/5 — Don’t get excited *2025-03-20* (SwiftyStoreKit.ReceiptError error O.) upon signing up for the free trial, while fully intending on paying the annual fee when it ends. Nothing better than finding an app that does exactly what you’ve needed, only to find out it doesn’t work. ### 1/5 — Not working at all *2024-05-12, version 1.7.0* I lost my time and money ## Frequently asked questions about SwifDoo PDF ### What are the main functions of SwifDoo PDF?
