Signature Share is a free Android app developed by Binary Solutions that allows users to capture and share electronic signatures. The app is designed for demonstration purposes only, and its functionality has been merged with the Signature Capture app. Users can download the Signature Capture app from the Google Play Store.

The Signature Share app is released under Apache License 2.0, and its source code is available on GitHub. Users can report any issues with the app on the GitHub issues page. The app allows users to sign by touching the screen and provides a context menu with options to view, share, rename, or delete signatures. The app requires a digital signature capture library, which will be prompted for installation later on. For commercial purposes, such as signing PDF documents, users can contact support via email.

Overall, Signature Share is a useful app for capturing and sharing electronic signatures. However, its functionality has been merged with the Signature Capture app, so users will need to download that app to use the features of Signature Share. The app is free and easy to use, but users should keep in mind that it is only for demonstration purposes.
