Best electronic signature apps on iPhone and iPad in 2021

Best electronic signature apps on iPhone

Our life is no more limited to our city, state, or country. And while that’s great for business, paperwork can be quite a pain. But thanks to some fantastic electronic signature apps, we can manage it all right from the iPhone; whether it’s an approval slip, proposals, contracts, or agreements.

But if all you need is a digital signature, apps like Microsoft Word, Photoshop, etc., can also handle the job. So, why should you especially opt for an electronic signature app?

Well, there are a few reasons behind it, and before I introduce you to the apps, let me help you understand their role in our personal and professional life.

Why do you need an electronic signature app?

An electronic signature is when you type or draw your name/initials on a document. While you can easily sign documents on your iPhone using the built-in Markup tool, it isn’t usually considered legally binding.

While sufficient for internal affairs, business transactions need something more solidifying and secure. Electronic signature apps offer more than just signatures:

  • Encrypt your documents – These apps use cryptography to protect your documents from prying eyes, keeping the details just between the sender and receiver.
  • Digital trail – From the origin of the document to the final sign, they could help you manage an audit trail, maintaining the document’s authenticity.
  • Legal benefits – Most trustworthy electronic signature solutions boast U.S. or EU government compliance. So, if there’s a court case, you have proper documents.
  • Push notifications – Probably my favorite feature; the real-time notifications help you stay updated and always on top.
