HScope

Turn your USB oscilloscope into a powerful portable lab

HScope is a specialized companion app designed to bring bench-style oscilloscope capabilities to your pocket, provided you own a compatible USB oscilloscope and a device with USB OTG support. Instead of being tied to a desk, you can carry out signal analysis wherever your projects take you.

The app supports a wide range of popular USB scopes, including models from Hantek, SainSmart, Owon, Voltcraft and others, as well as several DIY boards. There is even support for basic measurements through your device’s microphone input, which is handy for simple audio or low‑frequency checks when no hardware scope is available.

Once connected, HScope presents a clear, instrument-like interface with real-time waveform visualization. You can adjust time base and voltage scales, select channels, and inspect signals with good responsiveness, assuming your hardware is up to the task. For electronics hobbyists, students, and field technicians, this transforms a regular device into a surprisingly capable diagnostic station.

HScope is not an official tool from the oscilloscope manufacturers, and the developer explicitly declines responsibility for analysis errors or hardware issues. That warning, together with its evolving nature as a beta, means it’s better suited to experimentation, education, and general troubleshooting than to mission‑critical measurements where certified equipment and software are mandatory.

The learning curve is moderate: users familiar with traditional oscilloscopes will feel at home, while newcomers may need a short adjustment period to interpret traces and settings. Documentation and supported-device lists live outside the app, so checking compatibility in advance is essential.

Overall, HScope is a clever and highly practical solution for anyone who already owns a USB oscilloscope and wants the freedom to measure and debug circuits away from the workbench.
