After a system update you may be seeing an alert, that an application you just launched will be incompatible with future system versions (See: 32-bit app compatibility with macOS High Sierra 10.13.4 and later - Apple Support). The next version of MacOS X to come (MacOS X 15.x.y) will probably no longer support 32-bit applications.

Before you decide to upgrade or not next fall, make an inventory of your installed applications. You can get a full list of applications and plug-ins and their 64-bit status using the System Information utility.

To launch the System Information, hold down the options key ⌥ while clicking the -menu in the upper left corner of the display.
Click the first item "System Information".

In the system Information panel scroll down in the sidebar to Applications and click it.
Make the panel wide enough by dragging the corners to see all columns. You can make the columns narrower by dragging the dividing lines in the title bar.
Click the 64-bit column to sort the applications by 64 Bit (Intel) or not.

Looking at the result I can see that I will need new versions of Carbon Copy Cloner and Audacity, if I should decide to upgrade to a future MacOS 10.15 and I would have to say to GarageBand 6.0.5 and QuickTime Player 7, as no updates will be available.
