Best Adobe Acrobat Pro Alternatives and Competitors (2025)

Hello, sandra
You will have lifetime access to UPDF. However, if the software is entirely redesigned or upgraded, then it might need to upgrade. Customers are the persons who decide to upgrade or not. If they don't want to upgrade, they still have premium access to the current version of UPDF. :)

I agree. How is this a LTD if once they change the software it no longer works with your operating system. or say if Windows has a major update & it requires a core change in the software, then that basically means you may need to use a version of Windows that is older or unpatched to use the software. catch 22.

It is a play on words. Their interpretation of Lifetime is you download the current version of the software and you have it for life. However, this is a Perpetual license. So, when a new major version is eventually released, (e.g., version 3) you will then have to pay for that new major version.

It's a tool for a very specific user and purpose, it's for web developers or agencies who want to share the website with their clients. Then, clients can leave feedback on the site like they would on a PDF.

You would share a preview URL of your WordPress, Webflow, Next.js, etc site. Hope it's more clear now?

My users highly appreciate this tool's lack of login requirement and its seamless integration with any page. Since it's meant for preview/staging sites, I leave the login portion up to you; if you add a password to your staging site, it's already behind a login.

Leaving an email and name is under the "user icon". I will note that and will try to make its UX a bit clearer.
