### 1/5 — Misleading description

*2021-09-16, version 2.1.1*

Says in the App Store GOOGLE DRIVE SUPPORT (LIE) however, after buying it only supports WebDAV and Dropbox but NOTHING ELSE

LIARS

### 2/5 — Cloud services

*2021-05-26, version 2.1.1*

Guys why don’t you have the same cloud import options like Jotnot? Using Box.com and Drive and no option?

### 4/5 — This is my favorite SIGNING app, but...

*2020-12-11, version 2.1.1*

Good, basic signing app, but there is one odd flaw.  You can not resize or change the font!  
This is my favorite.pdf signing app.  Basic, as it doesn’t have all the costly “bells and whistles “ that are forced upon you in other apps.
Has ability to save signatures & initials, and duplicate them quickly throughout the document, but the size and font of inserted text are fixed (and the font used is rather LARGE for most document usage) and the font is very plain and austere.  Similar (if not exact) to the font in this review, only much bigger!
 Also, you are confined to the inserted DATE format, i.e. 12/11/20 is the only date format available!  It is almost like small issues are rarely addressed, and only major issues (like operating system changes) fixed.  Almost like there ‘is no development’ being done, except for major changes brought on by consultant developers and the company during major Apple changes - where as this “developer” is a mere “investment company”, a “shell” as a developer - just sitting back selling the app for profit with little to no improvements.  Their other apps, while good, follow this same bizarre pattern.
Would be PERFECT if these easy issues were addressed.

### 5/5 — 100%

*2020-04-28, version 2.1.1*

Brilliant well worth the money so easy to use

### 4/5 — Does the job.......?

*2019-07-02*

Very basic app but I like the option to outright purchase rather than subscribe.  Can resize font, pencil support, make duplicates.  Wish u could create folders to save docs

### 5/5 — So easy and convenient to work

*2018-12-29*

I usually am not big fan of writing reviews but this app is fantastic and was forced to write one.
Its easy to use & modify doc, specially editing/writing on pdf docs.
Awesome functionality with Text, signature , date etc..
Fab app..Thumbs up
5 star for sure.

### 1/5 — Stopped working

*2018-10-10*

Used this app for a month, but now it will not open on my iPhone 8. 
I uninstalled it and reinstalled. No change. When I try to open it, the app will open then immediately close.

### 5/5 — Great value! I will use this app for many years!!

*2018-10-06, version 2.1.1*

I was suspicious when the document did not register my signature upon signature. This is an easy issue. Make sure you save changes by selecting the “Document” button on top-left of screen. This will register the signature. Easy!

### 3/5 — Google drive-please

*2018-03-16*

Jot not scan connects to Google drive but signature does not. It takes multiple steps and saves to position file in right place for signature.

### 5/5 — This is a time (and Life) Saver!

*2018-01-08, version 2.1.1*

Highly Recommend For anyone who hates having to print and scan documents!
