### 5/5 — Wow! So glad I came across this app.

*2024-02-16*

I happen to be installing a new instance of NextCloud for a very specific purpose. While installing Pax Fax, I came across the Certificate24 extension. Thought I give it try. So glad I did. I was very skeptical, as the website didn’t have a lot of info. But, it works flawlessly. Would love to learn more about Certificate24. That said, I have it on one large and one small instance of NextCloud. I have the app on my iPad. I can’t believe there is no cost. I would definitely pay $10.00 for this app. I just hope in the future they don’t change and make it into rent-a-ware. To the developer, thank your for your time and hard work on this project. It’s awesome!
