ActivityLens: Activity Viewer

Current Activity, launcher & inspector overlay for Android devs. No root needed.

ActivityLens is a powerful current activity viewer, package name checker, activity launcher, and Android debugging tool built for developers, QA testers, and advanced Android users.

Need to know exactly which screen is open right now? ActivityLens shows the current activity name and foreground package name of any running Android app in real time through a lightweight floating overlay — no root, no ADB, no setup friction.

Whether you are debugging navigation, validating deep links, or inspecting activity transitions, ActivityLens gives you instant visibility into app behavior while you use your device normally.

IMPORTANT ACCESSIBILITY SERVICE API DISCLOSURE
━━━━━━━━━━━━━━━━━━━━
ActivityLens requires the AccessibilityService API to provide its core functionality.

• Why do we use this API?
We use the Accessibility Service API exclusively to detect window state changes. This allows the app to identify the current foreground application's package name and activity class in real time, so they can be displayed in the floating overlay.

• Do we collect or share your data?
No. ActivityLens does not collect, store, or share any personal, sensitive, or screen content data through this API. The data is processed strictly locally on your device for the sole purpose of developer monitoring and UI inspection.
