Ratings and Reviews
Nice to use
Pro:
I use it to read paper and book during my Phd study, convenient and useful.
Con:
I purchased the AI feature but didn’t purchase the Pdf feature, so it will leave watermark in my Pdf and the really annoyed.
Developer Response ,
Thank you so much for your encouraging words 🌟
We’re glad to hear that UPDF helps with your PhD studies. Regarding the watermark issue — this happens because the PDF editing/export feature is part of a separate license from the AI feature. If you’d like to remove the watermark, you would need to unlock the full PDF feature.
For more details or assistance, please feel free to reach out to our support team at support@superace.com , and we’ll be happy to help.
Would recommend!
The clean, simple and intuitive interface was the thing that prompted me to subscribe to their PRO version. I’ve tried tons of PDF editors available on the current market and I think UPDF definitely is among the top 3. You’ve got all the basics and a little more advanced tools you need for PDF editing. And for normal workload, this app is more than sufficient. The only improvement I hope to get is their AI “Ask PDF” layout: instead of cluster listing the numbered links that connect to specific parts of the PDF at the bottom, it’d be so much better to integrate them within the answer. Otherwise, I highly recommend this app for your everyday PDF editing!
No Custom Signature & Stamps - Already use Premium & Subscription the apps UPDF
Very Disappointed for this apps cause I can't upload my Own Signatures and My own Stamps. 1. To dev make sure your apps can do that things. I need to use handwriting Signature without using electronic Signatures. Also please make can add Unlimited signatures for save. 2. For Stamps I can't use my own Stamp via upload the image or pdf. And very limited to use the default stamp on this apps. So for Dev and Support team please add this feature also can Add unlimited Stamps to due i have an custom Stamp to use. 3. Totally I requested are can add custom signature (unlimited) also Stamp (unlimited). I very like to use your apps due have an Ai and clean modern design ui. But have an limited some section to use. Hope your can add that feature requested. Thanks
Developer Response ,
