01 / The problem
Why it exists.
Many PDF apps upload your documents to a server for simple jobs like merging or compressing. That is a poor fit for contracts, forms and identity documents.
PDF ToolKit does the work on the phone. There is no account to create and files never leave the device.
02 / What we built
What is inside.
