Call Billing

The app calculates call price automatically on outgoing calls, records it in its database, adds it to the monthly price.
Configuration possibilities:
The count unit can be set up(eg. 60 s taking a minute-based tariff), along with the default call price.
Different tariffs can be set to individual numbers (for example when you can call a number for free), and also to different phone number prefixes.
The app builds a handy history list of the outgoing calls with the prices of the calls in it.
The daily expenses are shown on a graph.
You get a notification on reaching 80% of your monthly price.
