### 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.

### 4/5 — App Does Not Work on IOS 13.1.3

*2019-10-22, version 2.2.0*

Very good app to use. But needs updating ASAP.

App does not work at all at the moment it keeps crashing out.

### 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.

### 4/5 — Works great.

*2019-06-21, version 2.2.0*

Easy to use and works well.

### 5/5 — Must download

*2018-10-04, version 2.2.0*

Easy to use and very convenient.

### 4/5 — Paperless

*2018-08-27, version 2.2.0*

Paperless is the way of the future. E-mailing the customer his shipping document at the moment he receives it is crucial these days.
