You may have hundreds of contacts stored on your smartphone’s address book. Some of them might belong to your social circles, while others could be business clients. Staying in touch with both types of contact groups on a frequent basis is equally important. As long as you can manage to remember whom to call when and how frequently, life is easy, but the problem arises when this list expands, and you’re required to remember calling preferences for each individual contact. This is where Nextcall steps in. Fresh to the Google Play Store, this free Android app brings forth a very simple yet effective purpose of keeping you informed about when you last called your contacts, and more importantly, when should you be contacting them next. To help you achieve said task effectively, Nextcall maintains separate logs for all calls made to your personal as well as business contacts, and lets you define default call scheduling preferences for both supported contact groups. The least contacted numbers are listed at the top, and you have the option to specify custom call reminders for every single contact. More on this simple app to follow after the break.
