AutoSilent is a utility app available for iPhone that automatically mutes your device during meetings, scheduled times, or at selected locations. With a 7-day free trial period, AutoSilent offers premium features such as schedule events, location events, and calendar events. However, these features require an auto-renewable subscription of $1.99 per month.

The app allows you to manage your subscription and turn off auto-renewal through your iTunes Account Settings. It also provides the option to restore purchases in case of any issues. AutoSilent synchronizes with your calendars and mutes your device during meetings, automatically reverting it back to regular/ring mode afterward. Additionally, it can detect your current location and mute your device when you're at school or the university, ensuring you don't miss important calls or get embarrassed by alerts during meetings.

Please note that the app requires access to your current location and notification permissions. It also comes with a battery disclaimer, as continued use of GPS in the background may decrease battery life.
