One UPDF app to rule them all

Have absolutly loved UPDF pro. It has allowed me to go through My Emails, Documents files, and everything else including Sheets, Google Drive and other drives and begin the process of organizing, consolidating, and eliminating duplicate with ease using the online cloud feature which also has allowed me to access on my iPhone or MacBook.

Even editing PDF's has become much more streamlined having everything I need in one application. Storage, organization, editing, signing, creation. I love this app.

I only wish I had more seats so I could use on my iPad as well without having to sign one device out.

I also have discovered that when I name a PDF anything that contains a "/" will not upload. Something I haven't brought up to the developers yet but will update the interaction here once I have.

But Hands down I recommend this application. I haven't tried the Ai and doubt I will only because I don't care to use applications that are subscription based but I am sure it's great based on my experince so far.

had PDF element, switched over to UPDF

I had the perpetual PDFelement plan for 3 years now. there were times when it froze up on me making it really frustrating. searching for topics would let me punch in 3 letters then itd freeze while it searches terms then proceed. Not to mention i had to pay a separate amount to get the mobile app (which works great on the ipad. its equal to UPDF in that regard).

UPDF is cheaper than most other pdf editors and it works across ALL platforms. this was helpful since i had a windows latop and a samsung phone but was considering switching over to apple and needed to know if i would have access to my comments embeded in the highlights from PDFelement. IT WORKED. all my notes transfered over, i can access on any device or operating system.

Gave 4/5 stars cause im not sure if theres a way to autosync the UPDF with my iCloud. ive lost information with PDFelement so now i try to save more frequently. maybe ill reach out to customer service to find that out. but in the last 3 weeks of using it for 9-12 hrs sometimes MORE every day 6 days a week i think this works very well. i would have encountered hickups by now.

It is wondeful app to study and make summarize the relevant point of one text. It use avoid the lost of time with not essential aspect of one text . It sd relevant to connect ideas, define trends about one topic, prepare presentation with the esence of one aspect, etc.
