ActivityLens: Current Activity is a free utility tool by moalduhun. It’s designed for developers, QA testers, and tech-savvy users as it lets them see real-time technical insights by displaying the current activity name and package name of the app they’re using via a floating overlay on their mobile device’s screen.

While it looks overly technical and complicated, ActivityLens: Current Activity is incredibly easy to use for debugging and QA testing. At the same time, its security is top-notch, since it does not collect personal data, store user-typed text, record audio, and capture screen content — basically, it doesn’t bypass privacy controls.

Effective for debugging and testing processes

ActivityLens: Current Activity isn’t built for casual users; instead, it’s for technically proficient individuals, such as quality assurance (QA) testers and app developers. With its real-time monitoring, users can see which activity is currently running. As you move across different apps, the floating overlay updates instantly, making it ideal for debugging navigation flows, tracking multi-activity processes, and better understanding activity lifestyle behavior.

The app also includes an activity log and history feature that automatically records every activity transition with precise timestamps. This allows developers to review navigation sequences, analyze screen flow patterns, and export logs later on for documentation or bug reporting. Additionally, it keeps a full copy history, making it easy to revisit previously captured data and reference important components when needed.

When talking about its interface and accessibility, it focuses on functionality rather than visual design, removing any unnecessary clutter that affects productivity and ensuring that no distractions get in the way of testers and developers. On top of that, first-time users are guided through a step-by-step process for its required permissions, including accessibility permissions and usage access — clearly explaining each one before you grant access.

Made for developers and QA testers

All in all, ActivityLens: Current Activity is an effective tool that shows you what’s happening deep inside your apps in real time. While it appears complicated at first glance, that complexity reflects its purpose — it’s built specifically for developers and testers. For debugging, analyzing activity behavior, and understanding app navigation on a deeper level, it proves to be a practical and reliable tool to use.
