SOP3A runs in a browser, so there is nothing you have to install. The Windows and Android apps are the same SOP3A in a window of its own — handy on a shop floor, or when you want it in the taskbar.
Nothing to install. Works on any computer, tablet or phone.
A desktop app for Windows 10 and 11.
Windows shows a “Windows protected your PC” warning the first time, because this installer is not yet code-signed. Choose More info, then Run anyway.

Android will ask for permission to install apps from this source. That is normal for an app that is not yet on the Play Store.
Get the Android appNot available yet. Use SOP3A in Safari in the meantime — it works well on a phone.
We will put it here as soon as it is approved. In the meantime, open SOP3A in your browser.
Do I need to install anything?
No. Everything SOP3A does works in a browser, on a computer or a phone. The apps are a convenience, not a requirement.
Is the app different from the website?
It is the same SOP3A. The apps add the things a browser tab cannot: its own icon, a window that remembers where it was, and downloads that land in your Downloads folder. Because the app loads SOP3A live, it is always up to date — you do not reinstall it to get new features.
Why does Windows warn me about the installer?
Because it is not code-signed yet. Windows shows that warning for any installer it has not seen signed by a registered publisher, whoever made it. Choose More info and then Run anyway. We are working on signing it so the warning goes away.
Does it work offline?
No. SOP3A needs a connection, because your procedures live with your team rather than on one machine. The apps tell you plainly when they cannot reach the internet.
