### 5/5 — Really good

*2023-07-16*

It’s convenient, but if you want to merge pdfs really quickly you’ll have to pay for it. It’s a good app to have available if you want to merge pdfs simply gets the job done.

### 1/5 — Too Many Bugs To Use

*2021-09-11, version 3.1*

I bought the lifetime merges feature for this app. Mistake. First, there  it only merges. It doesn’t separate documents. There another app that does both better for the same price. After I updated the app, it will no longer merge anything. I have deleted, downloaded, etc., and nothing. I wrote customer service and got no response.

### 1/5 — Doesn’t function

*2021-06-16, version 3.1*

I hit bugs at every step. I tried waiting 60-90 minutes for the free queue and got repeated “network errors” hmmm...is it a trick to force you to pay $10 to upgrade? I tried 2 other (worse) PDF combining apps and as a last resort paid the $10 but buttons were greyed out and app unresponsive. I closed app and retried and it said I hadn’t upgraded, and still didn’t work. Thanks for wasting my time and stressing me out!

### 5/5 — Simple & Clean

*2021-04-18, version 3.1*

Handy app that gets straight to the point! The simplicity of user interface is appreciated.

### 5/5 — Thanks

*2021-03-24, version 3.1*

You’ve made my document so easy to compile without having to hassle others on how to do this.

### 2/5 — App paid but not working after 4 days

*2020-12-05, version 3.1*

I upgraded from free to paid app because free app takes 1 hour to convert 5 pages documents. The paid version takes 1-2 minutes to convert. But app stop working after 5 days and it’s been over a week and I emailed customer support and no reply from the company. I hope this app gets fixed soon or please refund my money.

### 3/5 — Pro is pricey

*2020-11-03, version 3.1*

This extremely simple and low budget made app should cost no more than 3$ for the pro version. You only get 3 free tries. After that, to buy the pro unlimited version it’s 7$. Way too much. I'd buy the pro if it was about half the cost. This app developer blocking their blessings. More people would buy if it was cheaper.

### 4/5 — Delivers!

*2020-08-27, version 3.1*

The only criticism... it doesn’t show the progress as the combined file is being created. After several minutes I had given up. Then it was suddenly finished. Still no sound effect or chime or graphics.

### 4/5 — Gets It Done and Beggars Can’t Be Choosers

*2020-04-14, version 3.1*

(**it’s only free if you’re willing to wait 60-90 minutes for your merge)

If you’re tighter on cash than you are on time and value simplicity and effectiveness over extra perks, then I think you’ll be happy with this app. 

It’s easy enough to use. You can view the documents you’ve added to the merge list and adjust the order. Sometimes, I had trouble finding my documents from the app’s upload options, but that was easy to overcome by opening the documents and sending them to the PDF Merge app. (Note that I am a PC/Android user learning to function and access my files on someone else’s iOS, so pure iOS users with their own device might not have this issue at all—but hey, that speaks to the simplicity and intuitiveness of this app).

I suppose I would rate it higher if it let you work on two merges at the same time or to upload documents that could be reused for subsequent merges, but this is a free app, so I don’t expect those features.

### 2/5 — Not optimal; no developer response to feedback

*2020-02-14, version 3.1*

The app does what it’s supposed to do, but at such a slow rate that it’s almost not worth it. If one were to use combinepdf online, one could merge dozens of PDFs in the time it takes this app to create one merged file. Despite the myriad reviews corroborating on this issue, the developers must be negligent in responding to user feedback in any meaningful way, since, in the several months that I’ve had this app, no improvements either to user interface (e.g. how it refuses to accommodate for screen tilts) or this abhorrent sluggishness have been made. At least it works, but considering that no updates seem to be incoming, I can’t authentically give any more than two stars.
