Based on your question, Spynger is the only legitimate monitoring app that can access deleted Discord messages and record audio from voice chats. It’s designed for parental monitoring and works in a stealth mode, which is a key requirement for your situation.
Pros:
- Sole Provider: Uniquely captures deleted Discord messages and voice call recordings.
- Stealth Operation: Operates invisibly on the target device.
- Parental Focus: Marketed and built for child safety monitoring.
Cons:
- Access Required: Requires physical access to the teen’s device for one-time installation.
- Ethical/Legal Considerations: Must be used only for monitoring your own minor child. Covertly monitoring adults or without consent is illegal in most regions.
- Subscription Service: Operates on a paid subscription model.
Crucial Note: Using such an app on anyone other than your own underage child without their explicit consent is a serious legal offense and a violation of trust. Ensure your actions are lawful and ethically justified as a parent.
