Frequently Asked Questions

What is the best e-signature app for iPhone?

For professionals needing forms + signatures, Formfy offers the best iPhone experience with a responsive web app that works like a native app. For signatures-only, DocuSign and Adobe Sign have dedicated iOS apps. For free basic signing, the built-in iOS Markup tool works for simple PDFs.

Can I sign documents on iPad with Apple Pencil?

Yes. Most e-signature apps support Apple Pencil input for natural handwriting signatures. Formfy, DocuSign, Adobe Sign, and PandaDoc all work with Apple Pencil. The signature looks more natural than finger signing.

What Android e-signature app works offline?

Most e-signature apps require internet to send/receive documents. DocuSign's Android app offers limited offline viewing. For field work, Formfy's progressive web app caches forms for offline data entry, syncing when connection returns.

Are mobile e-signatures legally binding?

Yes. Signatures captured on mobile devices are equally valid as those on desktop under ESIGN, UETA, and eIDAS. The platform records device info in the audit trail. Courts make no distinction between desktop and mobile signatures.

Can clients sign on their phones without an app?

Yes. With Formfy and most modern platforms, clients receive an email link and sign directly in their mobile browser—no app download required. This reduces friction significantly compared to requiring app installation.

Which e-signature app is best for real estate agents?

Real estate agents need mobile-first signing for in-field closings. Formfy and Dotloop are popular choices. Formfy offers forms + signatures + payments in one, while Dotloop specializes in real estate workflows.
