E-mailing the customer his shipping document at the moment he receives it is crucial these days. ### 4/5 — Love love love it!! *2017-08-08, version 2.2.0* Sign PDF makes my job a breeze! I can do business without a lot of fuss and expense! ### 4/5 — Love it!! *2017-08-03, version 2.2.0* Took me a bit to figure it out but once I did it has been so helpful!! ### 5/5 — Super Convenient *2017-07-07, version 2.2.0* Easy to use and convenient when there is no printer available. ### 5/5 — Best sign app *2017-05-25, version 2.2.0* This is my favorite sign app. It's easy to use and doesn't have glitches like others. ### 4/5 — Great app *2017-04-14, version 2.2.0* Works great for editing and signing documents on my mobile device. It's a bit annoying that you have to purchase credits after a vey small allotted credits offered ### 5/5 — Great *2017-04-02, version 2.2.0* AwesomE ### 5/5 — Great app *2017-01-26, version 2.2.0* So easy to use to sign legal documents with ease ### 5/5 — fantastic tool *2016-11-30, version 2.2.0* great work！ ### 5/5 — Perfect *2016-11-02, version 2.2.0* Perfect app ### 5/5 — Easy to Use *2016-10-24, version 2.2.0* After I figured out how to send PDFs to this app (in my e-mail, I selected the PDF attachment and then scrolled right to "Copy to SignPDF"), it was easy to use. It came in handy when working from home. ### 5/5 — Very user friendly. Almost easier than pen & paper. *2016-10-17, version 2.2.0* Such a user friendly interface. I use this to submit claim forms practically effortless! And free to boot! ### 5/5 — Awesome app *2016-10-04, version 2.2.0* Very useful for signing PDF documents. Immensely increased my productivity on the road. ### 4/5 — Great App *2016-10-01, version 2.2.0* I love this application. It's so easy to use and makes signing documents easy also. You can have more than one signature, so if you have to use a title, put it in. ### 5/5 — Very good work *2016-09-28, version 2.2.0* Good work well done! ## Most critical reviews (10 lowest-rated) ### 1/5 — What happened!???? *2019-10-20, version 2.2.0* I purchased this app a year ago. I paid the one time fee for unlimited PDF edits. It was working great, but now the app won’t open on my tablet or phone. I’ve deleted and re-downloaded it numerous times. All of my documents are inaccessible and I use this app for business. I can’t even get the app to load past the grey screen. If admin will reach out to me, I will adjust the rating , but right now this is unacceptable to be advertised as a pro app. If you sell it...support it. ### 1/5 — cannot use *2019-02-22* Cannot ues ### 1/5 — Not working *2016-12-31, version 2.2.0* I bought both models of the app and I used them a while but they stopped working. I contacted the app maker and they never helped their support department is very bad. wasted money! ### 1/5 — Save your money *2016-04-02, version 2.2.0* Try Adobe fill & sign free app works easier and better ### 1/5 — Not working right *2016-02-17, version 2.2.0* It was a great app before. But recently it's not working right. The signature won't show where it should be.. ### 1/5 — Glitchy! *2015-11-16, version 2.2.0* Tried multiple times to align and when I click save the final pdf smears work. Don't waste your time and money. Totally regret buying credits. ### 1/5 — Don't waste your money or time *2015-10-08, version 2.2.0* As soon as I paid the $14.99 for unlimited credits for signing documents, the app stopped working. It freezes and crashes every time I try to use it. Their website is not found so you can't even get any app support or give them feedback. ### 1/5 — Does not load since update *2015-09-27, version 2.2.0* New update & it still sits there just loading. Please fix as it is used for my work. Absolute rubbish!!!! ### 1/5 — Terrible User Experience *2014-12-28, version 2.0.0* I downloaded this app to fill out some paperwork in PDF format. I added my information, which was time consuming because every line of text had to be adjusted for size. Not the developers fault, but the process was cumbersome and could have been streamlined a bit. But the real nastiness came when it was time to export the completed documents. I was then informed it would cost a "credit" to export a single document, and I had four "free credits." As I had five documents to export, I would have had to pay $2 for the smallest "credit" package, for an app that I would now never use again. Fortunately, I was spared this expense when I did a test export of the first four documents and found out that the exported PDFs were unreadable by Adobe Acrobat Reader. Not particularly useful. I ended up printing and scanning my documents and plan to avoid useless signing apps in the future, and I advise anyone reading this to do likewise. -Michael ### 1/5 — Crashes *2013-05-23, version 1.0.0* Terrible app, crashes every time you try to save or email edited PDF. ## Most praised reviews (10 highest-rated) ### 5/5 — Fair pricing *2020-07-14, version 2.2.0* Love this app. It offers the free version, and always the paid version lifetime. ### 5/5 — Must download *2019-06-13, version 2.2.0* Love this app!
