Mac apps to “cleanup your computer” ?

Mac OS runs maintenance scripts automatically that take care as any "cleaning" needs that may develop.That started about 20 years ago. Macs also self-defragment.

Adding useless third-party cr@pware is only falling for scams, because the computer world knows Macs have those maintenance routines that take care of any issues.

Macs are like cats--they clean themselves. The only thing you need do is to restart the computer once every 1-2 weeks to freshen things up.

Never use any app that claims to speed up or clean your Mac.

Macs do not need "cleaning". They don't have files installed all over creation as they do in Windows. For any basic cleaning, such as clearing cache files, you can do that yourself without the need of any other software.

Are Mac apps to “cleanup your computer” any good?

No, no, a thousand times no. Also don't install any antivirus app.
