### 1/5 — Problem

*2025-02-14, version 1.8*

Cannot get it to show the text but will in Adobe.

### 2/5 — Love the app but….

*2023-12-29, version 1.6*

This app is very user friendly, however sometimes when I email the document, it can take more than a day to arrive in my inbox. Please fix this glitch

### 1/5 — Whoops not on an iPad 2 buddy

*2023-09-26, version 1.6*

Whoops not on an iPad 2 buddy.  Didn't do anything, probably choking on file sizes.  The 4.99 did make the ads go away, so that's nice.

### 1/5 — This app is a rip-off it doesn’t let you do anything but color things no text editors

*2023-09-07, version 1.6*

I want my money back

### 1/5 — The app keeps on closing while working on it

*2023-03-09, version 1.6*

Terrible

### 1/5 — doesn’t work

*2021-05-13, version 1.6*

I bought the paid app and the app still doesn’t work properly. Poorly made. Don’t buy.

### 1/5 — Doesn’t Work

*2021-03-28, version 1.6*

I upgraded but could not get access to my PDF files to export them. So I wasted my money. I’ll have to do my work in another app.

### 1/5 — Useless

*2020-12-25, version 1.6*

Bought the paid version but could not print my pdf.. printed half way and it exit the application.. waste of money..I would like a full refund

### 2/5 — JPEG export crashes every time

*2020-10-26, version 1.6*

An absolute necessity is to be able to select multiple pdf’s at a time to send by email. Sending one attachment at a time for a business email is really unprofessional! Ether this gets fixed soon or this app get deleted.

This version doesn’t import pdf’s properly. Signatures and notes don’t show up anymore. The app seems unable to import many pdf’s now and crashes instead.

Overall I like the app but the jpg export option doesn’t work. Needs to be fixed.

Marking up pdf’s is great but the ability to use folders would be very handy. The colour coding is pretty much useless because you have to just remember which colour matches which project - instead of just naming a folder as the project.

I find myself using this app less and less and these glitches add up without getting fixed. This was once my go-to pdf app but it rarely works anymore.

### 1/5 — Good idea bad execution

*2020-10-22, version 1.6*

Paid for the upgrade to be able to send files easily via texts and the layout doesn’t allow for me to access the send button. Also saves as file number.pdf as opposed to what I actually named the file. Waste of money to upgrade since I am doing exactly what I did with the free version...
