If you searched for “hidden spy apps,” the more useful question may be how to tell if someone is spying on your phone—and what to do without increasing your risk. There is no defensible current top-five list of apps to recommend for covertly monitoring another person. Software used to monitor someone without consent or persistent notification is commonly called stalkerware; this guide explains possible warning signs and safer next steps.
What “hidden spy apps” usually means
The Coalition Against Stalkerware uses stalkerware for software that enables remote monitoring without consent and without explicit, persistent notification. The Federal Trade Commission (FTC) describes it as software installed on a phone or other device without its owner’s knowledge. “Spyware” is a broader term that can also refer to tools used by governments or criminals.
Depending on the software and its access, monitoring can include tracking location, reading messages or email, accessing photos and videos, observing online activity, or activating a device microphone. These capabilities describe what stalkerware may do; they do not mean that any particular app is on your phone.

There is no single symptom that proves stalkerware is installed. The FTC suggests treating a cluster of unusual device behavior or unusually specific knowledge by another person as a reason to consider the possibility—not as a diagnosis.

Battery and performance problems can have ordinary causes, so do not conclude that a monitoring app is present from a symptom alone. The FTC’s warning signs and safety guidance are at Stalkerware: What To Know.
What to do if you suspect a spy app on your phone
Think about safety before investigating or changing the device. The FTC warns that calls, searches, or removing software may alert the person monitoring you. It advises contacting a domestic-violence advocate before attempting removal and not contacting an advocate or law enforcement from a device you think may be monitored. The Coalition Against Stalkerware also cautions that removal or significant changes may be detected and could increase abuse or harassment.

- Use a safer device to seek help. If you can, contact a trusted advocate or support service from a device the other person cannot access. If you are in immediate danger, seek help using a safer device or through someone you trust.
- Discuss the risk before changing anything. An advocate can help you weigh whether investigating, removing an app, or changing device settings could create additional danger. Avoid confronting the suspected person based only on device symptoms.
- Make a plan for device changes. Do not immediately delete an unfamiliar app, reset the phone, or install a scanner on the device if doing so could alert someone. A security scan may identify some threats, but a scan cannot be treated as proof that stalkerware is absent.

What app-store rules do—and do not—mean
Google Play policy allows monitoring applications only in restricted, policy-compliant parental or enterprise contexts. The policy requires prominent disclosure and consent; it does not make covertly monitoring a partner acceptable. Google Play describes stalkerware as monitoring that violates its rules, and Play Protect’s warning reads: “This app can spy on you by monitoring your location or your activity on this device.” That warning is an alert about an app category, not a diagnosis of a particular phone.

What the SpyFone case establishes
In a December 2025 release, the FTC said it denied Scott Zuckerman’s petition to vacate or modify a 2021 order related to SpyFone. The agency described the order as barring Support King, LLC and Zuckerman from offering, promoting, selling, or advertising surveillance apps, services, or businesses. This is a specific enforcement action, not a finding about every monitoring app or company. FTC: FTC Denies Petition from SpyFone App CEO to Vacate 2021 Order.
