This app helps me track my costs in real time with all the metrics from facebook itself (CPC/CPV).
It has saved us tons of money by showing us what we are paying vs actual performance as well as letting users know if they're getting value out of their ad spend. I dislike that it's difficult to export data into other programs like excel or google sheets so this could be improved upon at least somewhat. Try using it! We have been able to save quite a bit of cash over our previous tools while also providing more detailed information about how each campaign was performing and allowing feedback loops to occur without having to go back through multiple reports manually after every update.
