Great Idea, In Theory
Hiya is a great idea, but the app needs serious work. There is currently no way to mark a number as "not spam." If there is, its very difficult to find and the developers site doesnt help. Also, theres just a huge list of flagged numbers as opposed to a recent call list.
Deleting the app because of these issues, but would happily download a better executed version.
