The app is used to be able to calculate how many iMessages/Texts/Phone calls you've exchanged with a certain user.
You should also be able to save a current message thread with a user (and be able to export it to email, etc).
You also will be able to use this app to make sure to "hide" numbers so you can't contact certain individuals for periods of time. We would then add an In-App purchase (called 'Keys') which would allow you to contact them.
Please send a price and timeline with proposal. I wont provide artwork and designs
