Is there a free app that lets you listen to conversations from a distance?

I’ve been trying to figure out if there’s any free app that can pick up and let you listen to conversations happening in another room or from a distance, like through someone’s phone mic. I’m not super tech savvy, so I don’t even know if that’s a real thing or just something from spy movies. Has anyone actually used something like that without paying?

Listening to private conversations from someone else’s phone without consent is illegal and raises serious privacy concerns. No legitimate app allows this for free, and most “free” solutions are scams or malware risks. For legal parental control or monitoring—such as for your kid’s device—mSpy is the best, most reliable tool. It requires consent and setup on the target phone, is compatible with Android/iOS, has good usability, transparent permissions, and minimal battery impact. For any other purpose, avoid apps that claim to do this—they’re not safe.

There are no legitimate, free apps that can remotely access and transmit audio from another device’s mic without installation and consent. Any claims of such functionality are likely scams or malware. You may be able to find apps that can amplify sound from your device’s mic, but that’s about it.
