  • Bad Experience - App Crashes Repeatedly -I lose work

    By Dr. Barry Shaffer
    Purchased the editor a couple of days ago. I’m wishing I had not. The editing is clumsy. It sets things up in boxes that are hard to get into and then it divides them randomly. Doesn’t work well with blanks. In addition to it crashing over and over. And it doesn’t save before crashing. Feel like I wasted $9.99. 5th generation. Would not advise purchase.

  • Really, really sketchy

    By Woo ten
    I was really upset that this great program, that I paid $10 for a year ago,was disabled in the new IOS. I couldn't email or print my altered pdf files any longer. I think that was a bit greedy on their part. Then on their website it said basically, what are you complaining about, you spend $4.95 for a cup of coffee. True, but when I am half way done with my coffee, Starbucks doesn't come seal my cup and say "that will be another $4.95 if you want to finish it". I love this product, but have to say, if this happens again, I will deal with a less jazzy app. Because I am not going to be a rube. *****Update....they just did it again to me. Another $9.99 if I want to use the program tat I ave purchased now twice! Time to find another app!

  • Good but not Great

    This version and the previous version of the app seems to be hogging my battery. I can no longer get through the day with one charge. Battery usage statistics show that the app is eating up 80% of my battery! In addition, simultaneous editing and syncing on two different devices is a joke. I have tried suggestions from your support team, which didn’t help the situation. Refreshes take forever, which results in syncing issues. It is especially terrible on the Mac app. I never had this problem on Notability using iCloud sync, which leads me to suggest that there is an issue on the apps end. For being such an expensive app, I would have expected that simultaneous multi-device functionality would be standard. I use my iPad to write on the PDF and my MacBook to type on the PDF @ the same time. However, syncs either never occur or occur rarely, which is INCREDIBLY frustrating. It’s almost so frustrating that I am considering moving back to Notability. Lastly, Apple Pencil support and palm recognition support need to be vastly improved. This app is definitely way behind other note taking apps in that regard! I really love the other features of this app, however these need to be improved for this to be my one and only note taking app!
  • Surpassed Expectations

    When compared to other apps that focus mainly on scanning or even Adobe’s own subscription-based service, Expert 6 is solid. Having tried many, many scanner and PDF apps, I was at first surprised and then excited by the high-quality features PDF Expert 6 offers, especially when used with its sister-app, Scanner Pro. The pair of them made it possible for me to manage a 300-page mess of P.O.s and shipping documents with relative ease. Especially helpful are tools, such as color tagging for files and a stamp-pad tool that allows for custom images or text. All of the features are more or less intuitive, and there’s so many features that it always seems like more are left to discover. This app does not scan but it does allow for a really excellent digital environment for working with scanned files—basically, you can create custom notebooks, access drawing tools, import images, much of the same things you can do with note-taking apps, such as Notability. Add to this mix the revamped screenshot features of IOS, and whatever appears on your screen can become an editable PDF with just a few clicks.

  • Great app for reading/editing, but poor file management

    By kccnyc
    I’ve been using this app for years, but I have become increasingly disappointed with the Readdle teams’ inability (unwillingness?) to better integrate the app with iCloud. There are two ways to edit documents that are stored in iCloud: 1) Place them in the PDF Expert subfolder. Doing this allows you to open seamlessly from within PDF Expert, make edits/annotations, and have them sync back to that original folder seamlessly. 2) If a document is ANYWHERE ELSE in iCloud, you have to import it into PDF Expert. This creates duplicate documents, and basically breaks the seamless workflow required of a productivity app. This is disappointing, because PDF Expert works the way it should with other online file storage systems, such as Dropbox. You can open a document from anywhere in Dropbox (not a special “PDF Expert” folder), and it will sync back automatically without creating duplicates. This is also not something that can be blamed on Apple. Adobe’s free PDF annotation DOES allow you to open and sync back from anywhere in iCloud. This oversight needs to be corrected. Given how well Readdle does everything else productivity related, I can only hope this will be fixed in a future update.
