Auto Redial is a free utility and tool application developed by Solar Systems for Android devices. It allows users to redial numbers automatically with just a few taps. With this app, you can keep calling a busy number until it becomes available without having to manually redial every time.

The app is straightforward and easy to use. You can set the number you want to redial, the number of redial attempts, and the delay time between each attempt. Additionally, there is an option to enable/disable redial and to enable speaker mode when redialing. A widget is also available on the home screen to enable/disable redial.

One of the useful features of Auto Redial is the option to dial alternate numbers in a contact list, such as dialing a work number if the mobile line is busy. This feature can be especially helpful for users who need to get in touch with someone urgently.

Overall, Auto Redial is a simple and practical app that can save you time and effort when trying to connect with someone.
