FREE Junk Cleaner/Phone Booster App with NO ads

[HarborFront]

Most of the FREE ones come with ads which cannot be removed even by the paid AdGuard

I can only find the below with NO ads

1) Systweak Android Cleaner
2) Speed Booster

Anyone can find more?

Thanks

Maybe Files Go

My Xiaomi phone system is pre-loaded with their own Junk cleaner. So I don't bother to install another one on my phone.
