Bluetooth OBD2 Adapter for Leaf Spy and Dr Prius Apps
The Stahlcar ST350 is a compact Bluetooth OBD2 adapter designed for use with apps such as Leaf Spy and Dr Prius. It is a hardware interface that connects your compatible Android or iOS device to supported hybrid and electric vehicles, allowing the app to access vehicle data through the OBD2 port.
It is especially useful for Nissan Leaf and Toyota Prius owners who want to check battery-related information, live data, and app-supported vehicle details without buying a full handheld scan tool.
Best Suited For
The ST350 is best suited to Nissan Leaf owners using Leaf Spy and Toyota Prius owners using Dr Prius. It is ideal for drivers who want an app-compatible adapter for checking battery health, battery cell information, live data, and other app-supported readings.
It is not a general all-system diagnostic scanner. It does not include built-in software, service reset functions, coding, programming, or guided fault diagnosis. The features you can use depend on the app and the vehicle.
App Requirements & Costs
The ST350 is the adapter hardware only. Leaf Spy and Dr Prius / Dr Hybrid are separate third-party apps, and any app purchase or in-app purchase is paid directly through Google Play or the Apple App Store.
Leaf Spy Pro is a paid app. At the time checked, it was listed at $21.98 on Google Play and US$19.99 on the Apple App Store. App store pricing can vary by country, currency, platform, and later app updates, so please check the live app store listing before ordering.
Dr Prius / Dr Hybrid is generally free to install, but some battery test features require in-app purchases. The app developer notes that most features are free, while test features require an in-app purchase.

System Diagnostics
The ST350 is an app interface, not a standalone diagnostic scan tool. It allows compatible apps to communicate with supported vehicles through the OBD2 port. The diagnostic information available depends on the app being used, the vehicle, and the systems supported by that app.
For Leaf Spy and Dr Prius users, this usually means battery-related data, live readings, and app-specific vehicle information. It is not intended for full-system scanning across ABS, airbags, transmission, body control modules, or workshop-level diagnostics.
Service Functions
The ST350 does not include service reset functions on its own. It does not perform oil reset, EPB reset, DPF regeneration, battery registration, injector coding, ABS bleeding, key programming, or module programming.
Any available functions are controlled by the third-party app you choose to use. Stahlcar supplies and supports the adapter hardware, but the Leaf Spy and Dr Prius apps are separate products run by their own developers.
Vehicle Compatibility
The ST350 is designed for vehicles fitted with a standard 16-pin OBD2 port and is commonly used with Nissan Leaf and Toyota Prius models through compatible apps. It may also work with other vehicles and apps that support compatible Bluetooth OBD2 adapters.
For best results, check that your chosen app supports your vehicle model and that it supports this type of Bluetooth adapter before ordering.

Is This the Right Scan Tool for You?
The ST350 is the right choice if you want a reliable app-compatible OBD2 adapter for Leaf Spy, Dr Prius, or similar supported apps. It is a good fit for EV and hybrid owners who want to check battery and live vehicle data from a phone or tablet.
If you want a standalone scanner for reading and clearing fault codes across multiple systems, service resets, or general workshop diagnostics, choose a dedicated handheld or all-system scan tool instead.
