A Powerful Debugging App for Android Developer Assistant makes debugging native Android apps as easy as inspecting web pages with Chrome DevTools. You can analyze the view hierarchy, verify layouts and styles, preview translations, and much more — all directly from your mobile device. It’s ideal for apps built with Views and Fragments, with limited support for Android Compose, Flutter, and web-based apps.

A Powerful Debugging App for Android
Developer Assistant makes debugging native Android apps as easy as inspecting web pages with Chrome DevTools. You can analyze the view hierarchy, verify layouts and styles, preview translations, and much more — all directly from your mobile device. It’s ideal for apps built with Views and Fragments, with limited support for Android Compose, Flutter, and web-based apps.

Developer Assistant uses a blend of official Assist and Accessibility APIs, enhanced by advanced heuristics. This combination enables the app to reveal runtime information that most other tools can’t access. It’s designed to boost the productivity of developers, testers, designers, and power users in their everyday tasks.

Developer Assistant functions as a true assistant app — summon it anytime with a simple gesture, like long-pressing the home button.

INSPECT NATIVE & HYBRID ANDROID APPS

Developer Assistant can inspect applications built with the Android SDK. It works best with View- and Fragment-based apps, and offers limited support for Android Compose, Flutter apps, web pages, and hybrid apps.

PRIVACY-FIRST DESIGN

Developer Assistant does not require root access. It adheres to system security rules and prioritizes user privacy. All captured screen data is processed locally, offline, and only when you explicitly trigger the assistant feature.
For core features to work, set Developer Assistant as your default Digital Assistant app. You may also enable the Accessibility Service for more accurate inspections in nonstandard apps.

WHAT’S INCLUDED FOR FREE

A 30-day trial gives you access to one of the most advanced assistant tools for Android developers, testers, designers, and power users. After the trial, you can choose between purchasing a professional license or continuing with the free, limited version.

CHECK THE CURRENT ACTIVITY

Developers can instantly view the current activity’s class name — especially useful in large projects.
Testers can quickly access app version info, version codes, and shortcuts like App Info or Uninstall.

INSPECT THE VIEW HIERARCHY

Great for automation testers and developers debugging UI issues. View the full hierarchy of elements currently on screen, directly from your device, similar to web element inspection tools in modern browsers.

✔ View identifiers, class names, text styles, and colors
✔ Preview the best-matching layout resources next to their root views

VERIFY LAYOUT

Designers, testers, and developers can easily measure the size and position of UI elements directly on the device.
Whether you need to check spacing between two components or measure an element in density-independent pixels (dp), Developer Assistant provides the tools to confirm pixel-perfect (or rather DP-perfect) design accuracy.

SEE TRANSLATION CONTEXT

Perfect for translation teams. Developer Assistant displays translation keys directly beside text elements on screen, helping translators understand the context of each string.

✔ Translation keys displayed next to UI text
✔ Preview translations in other languages without changing the system language
✔ Check minimum and maximum string lengths across translations
