Drawboard PDF is a document markup app for reviewing and annotating PDFs. Its listing describes freehand ink, text highlighting, underlining, shapes, text, and inserted images. The interface can be customized with a toolbar of frequently used tools, and the app supports Apple Pencil input on compatible devices.
PDFs can be uploaded to cloud storage and marked up with collaborators in real time. The developer says Pro adds storage and advanced tools, including redaction, measurement, callouts, hyperlinks, audio notes, and an on-page ruler. The US App Store lists a free download, but does not state Pro billing terms or current prices.
Before sharing, check cloud permissions and recipient access, especially for contracts or personal records. Redaction should be verified by reopening and inspecting the exported PDF to ensure sensitive text is actually removed. We have not tested sync, measurement accuracy, or redaction behavior; retain an original copy before editing important documents.
