6 best signature apps for Android phones in 2026: Features, pros & cons

The first time I signed a writing contract in 2019, I used the built-in markup tools on my Samsung Galaxy A10. It felt quick and convenient, but I didn’t realize that my signature was basically an image. There was no audit trail, no time stamp, and no way to prove that the document hadn’t been altered after I signed it. If anything had gone wrong with that client, that signature wouldn’t have protected me. 

Many Android users also rely on PDF viewers or markup tools on their phones to scribble a signature and call it a day. But these tools lack tamper protection, identity verification, and a reliable way to track who signed what. That’s where dedicated signature apps make a real difference. They offer the same convenience of signing electronic signatures on a phone but with added technical layers that ensure its legality, including security, audit trails, compliance, authentication, and structured workflows to keep documents moving. 

Over the years as a freelance tech writer, I’ve tested dozens of e-signature apps across mobile and desktop. I recently reviewed the most popular options for Android users to find the best apps for everyone on both sides of the signing workflow. In this guide, you’ll discover the six best electronic signature apps for Android and their features, pros, and cons. Interested in seeing which app offers the best balance of mobility, ease of use, and security? Let’s dive in.

How to choose the right signature app for Android

If you search for “digital signature app” on the Google Play store, you’ll find hundreds of apps for mobile document signing. But many of them are awful to use or lack critical features expected from modern e-sign apps. Before choosing an e-signature app, it’s important to think about how you’ll actually use it. Some people just need a quick way to sign PDFs on their phone; others need workflows that keep documents moving across teams. No matter the case, evaluating your needs upfront makes it easier to choose an app that fits your volume, workflow, and budget. Here’s the criteria I followed in selecting these apps and some guidance to help you make the right choice:

• Define the volume of signatures and the workflow you need: If you sign documents occasionally, a lightweight tool may be enough. But if you send contracts regularly, manage approvals, or need templates and automation, look for apps built for higher-volume document processing. They usually include routing, reminders, reusable templates, and team dashboards. 
• Check compliance and security: If you’re signing anything business-related, legal compliance is non-negotiable. Look for apps that explicitly support the Electronic Signatures in Global and National Commerce (E-SIGN) Act; the Uniform Electronic Transactions Act (UETA); and Electronic Identification, Authentication, and Trust Services (eIDAS). These standards govern how e-signatures work. Also, look for apps that offer strong security features, such as encryption, user authentication, audit logs, and access controls, to protect your documents.
• Compare free vs paid options and pricing scalability: Many signature apps for Android offer free plans with limited signing, which you can quickly outgrow. Check how many documents you can send each month, whether templates are limited, and how pricing scales as your needs grow. You want to make sure long-term costs align with your expected usage.
• Prioritize usability: The best signature apps on Android make mobile document signing fast, not frustrating. Choose tools with intuitive interfaces, reliable PDF handling, and features designed for on-the-go use.
• Evaluate how the app fits into your existing workflow: If you send signed documents to your cloud storage, CRM platforms, or project management tools, integrations are essential for saving time and keeping documents synced across your systems.

The 6 best signature apps for Android I’ve tested and how I picked them

To make this list, I rounded up over 30 e-sign apps, but that was too many to test meaningfully. So I cut the list down by reading user reviews and checking websites to exclude any app that didn’t meet the criteria or had generally poor user feedback. That reduced the list to about 15 apps. 

For each app, I created an account, uploaded a test document, and sent it to another email address so I could sign as both the sender and the recipient to get a feel for the overall workflow. At this stage, I cut apps that took forever to load, crashed every time I launched them, were not intuitive, or didn’t seem like a good fit. Then I spent more time exploring the apps that passed and tested all their features. Based on all that, here are the six best signature apps for Android in 2026. 

1. Jotform Sign Mobile: Best for mobile professionals and structured signing flows
