I like it a lot.
I have just used it for the first time now on my newly jailbroken 7.04 phone and it's freed up just short of 1GB of memory by deleting unused language packs, keyboards, unused dependencies etc from my phone. I also really like the launch daemons feature which lets you disable things that run in the background like sending crash reports to apple, I'm sure this can only positively improve the performance of your phone.
Is it updated for the 5s?
Thanks
iCleaner is one of the most useful tweaks you can use
I went to the app store and there was no iCleaner, whats the actual name?
