Hello,
I can build Mac cleaning tool such like cclener. Do you expect to run on iPad & iOS as well?
what is the device factor you are looking for? I will do this project in two phase. First phase will have plain cleaning tool which will list catch files, downloaded files etc. upon clicking on Analyze button. ( with progress bar)
Once you select the type of file you want to clean, it will simply delete it.
In second phase, will implement more features and functionalities also depends on phase-1 feedback.
Thanks,
