SilentAlert Plus is an enhanced version of SilentAlert designed for iPhone users who often forget to switch their phones back from silent mode. This app introduces VOIP support and offers three main features for alerting users when their device is muted. The app notifies users when their phone remains silent for a specific duration, when they leave the location where it was muted, and upon arrival at specific locations. The badge on the app icon indicates the mute status, clearing once the device is set to ring again.

In the app, users can customize settings such as receiving alerts only once when muted, enabling vibration notifications, setting alert intervals, and configuring alerts based on distance traveled. Additionally, users can add specific locations to trigger alerts upon entry. To use location alerts efficiently, users need to enable "Location Services" with minimal power consumption and set them to always.
