With High Sierra coming soon should I invest in apps like CleanMyMac 3 or do you still say there is no need for these apps?

No need. What is it you are trying to do? If you want to tidy up your documents, you need to get in there and organize them yourself. An app can't make decisions like that for you.
As for files like cache files and such, macOS has been handling those for years, maintaining them and such. No need for a third-party app for that. You'd just be throwing your money away at best, at worst you'd be causing issue and slowing down your Mac unnecessarily.
If there is something specific you are worried about, let me know what that is and I can advise you.
Thanks Gary. Nothing specific just received an email promoting CleanMyMac 3 and they talk about left overs after deleting an app just by dragging to trash etc
David: Yeah, they need to try to justify themselves. To give you an idea, I checked 4 third-party apps and looked for their preferences files, which would be left behind if I dragged-and-dropped to uninstall. The average size was 100 bytes. Not kBytes, bytes. With a 250GB drive, that's 0.00000000037% of the drive. Anyone concerned about that should also be concerned after specks of dust inside your car weighing your car down and causing an increase in gas mileage.
Every once in a while you end up with some app storing 100K or so in your preferences file, but it is rare and still quite small. Any app that installs tons of things as a library or something will come with its own uninstaller (like Adobe apps do).
Many thanks Gary. I'll continue working without these programs as you have consistently recommended
My daughter has an iMac Air with 128 gb hard drive. The drive was low on storage, so she bought Clean My Mac 3. The first time she ran the app, 23gb of data was freed up.
Clyde: Impossible for me to know for sure what it deleted, but it could have just been temporary files, cache files and local backups, that would have been deleted anyway if she needed the space for something else.
