Are there any ad free speed boosters?

[RevealZero]

Title says it all. I'm looking for an ad free speed booster. I don't care if it's paid. I'm just tired of all the ads in all the speed boosters I've tried. TIA!

What kind of things are you looking to speed boost?
Most are just snake oil these days.

No speed booster app would be ad free. Your phone will be faster as well.

What do you mean by, 'your phone be quicker as well'?

I would suggest against using such apps. They might work for say, if you want to clear the cache, but if you want an app that interferes with RAM management etc, those would be detrimental to the device. Even clearing the cache manually is an easy task which could be accomplished in under a minute.
If an app claims that it can clean unused background apps out of RAM and that would speed up the device, I feel the developer doesn't understand how Android works. If the booster app is automatically killing apps, then you might get into a cycle of killing and reopening that would just drain the battery.
Android has come a long way in terms of memory management.
