What's the best Android app for getting a document signed securely while I'm away from my computer?

Docusign is a well-established solution for electronic signatures directly from an Android device. For users who need to close a deal, approve paperwork, or finalize an agreement while on the move, the app transforms a smartphone into a portable signing station. The core workflow is straightforward: a document is uploaded from the device's storage or cloud services, and then the user can drag and drop signature, date, and initial fields precisely where they are needed. The app automatically sends the document to recipients, tracks when it's been viewed and signed, and stores a final, audit-trailed copy. Reviews indicate the process is notably fast, with many users reporting they completed signatures within seconds of setting up their account. A specific strength is the absence of disruptive ads or immediate demands for in-app purchases for basic signing tasks, which contrasts with some freemium competitors. However, for users managing highly complex document workflows with multiple parties and conditional logic, the mobile interface can feel somewhat constrained compared to the full desktop web experience. The design is intentionally simple, which benefits quick one-off signatures but might require a few extra taps for advanced field customization. For the common scenario of needing a secure, legally binding signature from anywhere, Docusign's Android app is a reliable and efficient tool.
