This app provides you a handy call list, based on likelihood of dialing in your approximate location, part of the day and day of week. Moreover, you can send an SMS just via single long-click on the contact!
If you currently spend 3 seconds per action on messing with standard contact list, and you call 10-20 times a day, this app will save you 2 to 4 hours of your time per year.
No setup required, zero options to tune. The application sets up a reasonable guess for you already based on your call history, the first time it launched.
CoolCall reports no statistics or personal data over Internet, but it requires the permission to display the advertisements.
