Genius Sign is the best app to sign, date, and annotate your documents.

“Genius Sign shaved off about 30 min of my daily routine.” – Jane D., realtor
“I wish I had known about this app before” – Mike C., business owner.

Have you ever had to print a contract you received by email, to be able to sign it and scan it before sending it back? Well, Genius Sign is now going to save you a lot of time, trouble, and paper.

With Genius Sign, import any document, insert your signature, some text, the date, and export it wherever you need to.

To sign, draw your signature on the screen with your finger. You can also scan your actual handwritten signature with our award-winning scanning technology for a realistic rendering.

Genius Sign features two smart technologies that save you tons of time:
“Sign Here” magically detects the pages you need to sign, avoiding you to browse through the entire document.
“Auto Repeat” enables you to repeat your initials on all the pages.

Genius Sign is free to use and has no limit on the number of documents or signatures that you can manage. Should you be interested in the premium features, you can decide to upgrade to Genius Sign+.


- Create and save new signatures, either by drawing or scanning them.
- Import PDF, Word or image documents.
- Insert text and date, change their format, color, style or size.
- Precisely position your annotations.
- Quickly locate the signature fields with our Sign Here feature.
- Import documents from Genius Scan, your Photos library or any cloud service.
- Export your documents by email or to other apps.


+ Have guests sign documents without keeping their signature in the app.
+ Flatten annotations so that no one can modify them.
+ Repeat your initials on every page of a document.
+ Export to your favorite cloud service (Box, Dropbox, Evernote, FTP, Google Drive, OneDrive, OneNote, SugarSync, WebDAV).
+ Print documents with AirPrint.
+ Duplicate documents with or without their annotations, to reuse them as templates.
+ Password-protect and encrypt your PDF files.
+ Protect Genius Sign with Face ID, Touch ID, or with a passcode.

A Must Have

I am not sure that I have ever taken the time to write a review about anything, but I was just asked to rate this app, which I gave it a full 5 Stars. I was then asked to write a review. I won’t bore you with detail of why this App is top notch, as I don’t have to. It’s free give it a try. Regardless of whether you have a fast passed job or not, the three Genius Apps (Scan, Fax, Sign) work very well and integrate seamlessly with each other. The only cost I have decided to to pay for is for cloud storage and faxing. The days of using large, scan, copy, fax machine are in my rear view. How many people are sick of having to print something out just because they have to sign it and then scan it back in to send the signed document back? These three apps allow the user to do all of this right from your phone without paper and within seconds. It also allows sharing documents using just about any type of sharing account; Google Drive, Drop Box, One Drive, etc. I am aware there are many apps that do this. That said, when you combine the user friendliness with the cost or lack there of it’s unbeatable. That’s my two cents.....

Genius Sign - makes signing documents easy and secure

I used to wait until I get home in my laptop to be able to sign documents electronically. With Genius Sign App, I can now access documents needing signature even when I am not at home working on my laptop. I use Genius Scan often and found Genius sign last month. I downloaded the app, and went through the tutorial today. It was brief and easy to follow in the iPhone screen. I just sign my first document using this app and was successful forwarding the signed document to my team. Definitely a 5 star for its accessibility and security.

Missing Information

So what I’ve found is that when someone emails me a time card or some other document I found see all the information on it and then I’d import it to the Genius Scan app where it seems some of the information does not appear. I may see their signature at the bottom of the document but the important information in the body is missing. It’s hard for me to explain without sending an actual copy for you to see. The documents are sent to me as either a PDF or sometimes a .jpg but the results are the same. I see everything then import it and some of they typed in portion disappears but at the bottom of the document is signed by the sender and I sign and send back without realizing there’s info missing. Another comment which I made before but never answered is why if I have a document that has colors in and I scan it that it’s always just black and white?
