Forgetting to turn off Silent Mode and missing calls at the most important moments? SoundOn can help you! The app works based on notifications. If you want someone to be able to reach you even when Silent mode is on, ask them to send you a message via messenger with a codeword. When your device receives this message, SoundOn will automatically turn off the Silent mode (and/or Do Not Disturb mode), turn the call volume to maximum, and you will definitely hear the next call!
