The Problem: Most PDF signers are bloated, require subscriptions for everything, and upload your sensitive documents to the cloud.
The Solution: I built Signis! to be the simplest, most private way to handle documents on Android. It works entirely offline: your signatures and data never leave your device.
Some features: Sign anything, PDF Toolbox, Watermarks
