Go64 Editor's review

Go64 provides a fast, free way to get a comprehensive look at your 64-bit app compatibility and avoid surprises before installing macOS Catalina. Take an inventory of the apps on your Mac and see which ones are still 32-bit. Go to a developer's website or search the web for update or upgrade information. Keep track of upgrade costs so you can plan your spending to get all the upgrades you need. Any app that's built with Apple's 32-bit software libraries will need to be updated so it will run in 64-bit mode. These are primarily older applications, but some newer specialty apps are also still 32-bit.
