I know this question is not related to programming, but after brief google search, i've seen that there are multiple apps in market which can block apps, read time of use spent in app and can also read text,what's app messages without jail break I just want to know starting point to make such an app for personal use, I have no intentions to upload it to app store, so i could use API's app store don't allow
Any small link, book or reference will be appreciated
thanks
