Now you have an app for your device that allows you to think twice before making that call you want to do but you should not be doing.
This app is not like any other app to block contacts or block incoming calls or pass tests to prove that you're sober and you can call. On the contrary, you can always make the call whenever you want but if it is with a contact that you have added to the black list you will see a lock screen where you will have to confirm that you really want to make the call. Confirm a call is very easy for anyone, and sometimes you're not in your best judgment, so the way the app allows you to make the call is making a small charge through Google Play, so you'll have to think twice or more if you really want to talk to that contact that you should not call .
The app also allows you to get free credits to make calls instead of making a payment via Google Play, so you'll always can call that improper person, but, you will have to think about it several times.
The Log of the app lets you see the date and time of all call attemps you make to a blocked contact, as well as see if you confirmed the call or if you decided to cancel it.
