Known stalkerware
Installed apps are compared against a public, maintained list of surveillance products, by package name and by signing certificate, so renamed copies still match.
Sweep
A plain-language phone checkup.
Beta. Experts in domestic-violence tech safety have not reviewed Sweep yet, so treat it as one tool, not an authority.
"Is something on my phone watching me" is a normal question with a hard answer. Sweep checks the specific places surveillance apps live: the list of installed apps against publicly identified stalkerware, device admin powers, accessibility services that can read your screen, apps with no icon, and installs that came from outside any store. Then it explains every finding in words, not scores.
The checkup itself runs in the Android app, because a web page cannot and should not see your installed apps. This page explains how it works.
Get the app
Sweep for Android asks for one permission: the ability to list installed apps, which is the whole point. It has no internet permission, so what it sees cannot leave your phone, and it keeps no history of results.
On an iPhone? That button will not help you: this checkup needs an Android-only permission that does not exist on iOS. The explanation on this page still applies to your phone; there is no working checkup to install yet.
What it checks
Device admins
Apps with administrator power can lock the phone, wipe it, and resist removal. You should recognize every name on this list.
Accessibility services
These services can read the screen and watch input. Wonderful for accessibility, and the favorite hiding place of watchers.
Hidden and sideloaded apps
Apps with no icon, and apps installed from outside any store. Plenty are legitimate; the point is that you get to look at the list.
What Sweep will never tell you
That you are safe. A checkup can only report what its checks found, and sophisticated spyware works hard to fail them. Sweep says "these specific checks found nothing" and means exactly that, no more. If your gut says something is wrong, trust it over any app, this one included.
If you are in danger
If someone in your life may have put software on your phone, be careful with this checkup: removing an app or confronting the person can escalate things, and some spyware reports its own removal. Advocates who handle this every day can help you plan first. In the US: the National Domestic Violence Hotline, 1-800-799-7233, thehotline.org. Tech safety guides: techsafety.org. Worldwide: stopstalkerware.org lists local organizations.
The "Leave fast" button in the corner works from every screen. It instantly switches this page to an ordinary weather site and clears whatever the checkup found, in case someone walks in.
Data sources
The stalkerware list comes from the stalkerware-indicators dataset maintained by Echap (github.com/AssoEchap/stalkerware-indicators), licensed CC-BY 4.0, bundled with the app and refreshed each release. Echap does not endorse Sweep. Nothing is fetched at runtime, because the app cannot reach the network at all.

An app on this phone can read the screen as text right now, because accessibility access is turned on for it. That means the checkup results below could be visible to it too.
Screen readers and voice controls need this access, and so do plenty of ordinary automation apps. Sweep only recognizes a couple of screen readers by name; anything else on this phone will need your own judgment. Continuing will show you its name in the accessibility list.
Before acting on anything above
If the person who might be watching is someone you know, talk to an advocate before removing anything: removal can be noticed. National Domestic Violence Hotline (US): 1-800-799-7233. Tech safety planning: techsafety.org. Local organizations worldwide: stopstalkerware.org.
