Hadn't heard of iblacklist so checked on it and see mostly poor reviews. Sounds good tho but would be hesitant to try it for $3. Do you use it and if so, do you like it?Interesting... these options that you mention are better than nothing (of course), but a far cry from what is offered with iBlacklist.
Wonder why the iBlacklist author won't port his app to Android.
Is he afraid of others stealing his code, it being not feasible perhaps, or something else entirely? Or maybe he just doesn't have any interest?
EDIT, further checking I see numerous apps called iblacklist and all different devs.
