LAUNCH CRP919E BT / CRP919X BT currently does not support the oscilloscope module, so is there any way to install a third-party oscilloscope APP for vehicle diagnosis? The answer is yes, this article will introduce how to do it.
LAUNCH CRP919 series uses Android operating system, so third-party APPs can be installed.
After opening X-431 APP, select [Other Modules] -> [Files] -> [APP]. Under this menu you can see most of the applications of CRP919.
Open [Google Play Store], you can install various software, such as YouTube, Chrome (for web search).
For oscilloscope applications, you can choose the [HScope] APP.
Note: After installing [HScope] from [Google Play Store], its icon may not appear on the main interface. You need to open it in [Other Modules] -> [Files] -> [APP] interface when using it.
After we have the HScope APP, we connect the oscilloscope device and can view the band diagram on the LAUNCH CRP919 tool.
About Oscilloscope Functionality via Hscope App:
Although not officially compatible with Launch’s own oscilloscope, the CRP919E BT can become a capable scope tool using the Hscope app, developed by Martin Loren and available on the Play Store.
To use the Hscope app effectively, you’ll need compatible USB-based oscilloscopes such as:
High-resolution and sampling rates
Ideal for automotive signals (e.g., CAN bus, sensors)
Supported, but Hscope app limits usage to 4 channels unless additional licenses are purchased
Note:
The app performs best with 2-channel scopes and high-resolution hardware. Lower-end 8-bit scopes may struggle with fast signals.
The Hscope app is incredibly versatile, offering a variety of useful features:
While the free version of Hscope supports a single channel, paid licenses unlock additional channels and automotive-specific modules, with prices starting around $20—an affordable upgrade for enhanced functionality.
Conclusion
While the CRP919E BT doesn’t support Launch’s official oscilloscope module, its open Android platform allows you to install powerful third-party tools like Hscope. This transforms your scan tool into a multi-functional diagnostic device that can analyze waveforms, browse the web, and stream repair content—all from one compact unit.
Finally, for the selection of oscilloscope equipment, we recommend LAUNCH O2-2 (4 Channels) or LAUNCH S2-2 (2 Channels) for fuel vehicles, and LAUNCH EM101N (2 Channels) for electric vehicles.
