Adobe Acrobat Sign is a powerful mobile app designed for getting electronic signatures on documents and forms with ease and security anywhere you go. This app complements the Adobe Acrobat Sign e-signature service and requires an active Adobe subscription.

With Adobe Acrobat Sign, users can instantly open and sign documents directly on their screen with a finger or stylus, send documents to others for signature, and track the progress of agreements in real-time. It integrates with popular cloud storage services like Google Drive, Box, Dropbox, and Adobe Document Cloud, making document management efficient for business workflows.

The app is tailored for professionals and companies, ensuring legally binding, encrypted, and compliant e-signatures according to global regulations like the U.S. ESIGN Act and the EU eIDAS Regulation. Additionally, the app provides identity verification, an audit trail, and tamper-evident seals to protect both senders and signers.

Besides e-signatures, Adobe Acrobat Sign also allows scanning physical documents to PDFs with features like boundary detection and perspective correction. This makes it a comprehensive tool for handling paperwork digitally and securely.

However, while it offers robust features for business use, some users report issues with signing in and app stability that can impact usability. Adobe continues to improve the app's performance and reliability with updates.
