I’ve finished the development of the PDF Generator Adalo component, which can generate PDF within your Adalo Application (Web,iOS&Android) without requisition any PDF generator services.
Currently, it is on review in the Adalo Market place. I hope it soon will be available there.
As for now, it can be installed from https://itsmi.store/components with 14 days trial period.
