The Most Powerful Software
Free MetaBase App on Android, or iOS
The MetaBase App imports your data via Bluetooth into the device of your choice, stores it, and optionally transfers it to our secure Cloud platform.
Use the App to configure the sensors at any frequency. Set the real time streaming or logging mode. And go!
You can also troubleshoot and upgrade the Firmware of your MTR.

Develop Your Own Apps
Use our developer tools to build your own App.
Develop Apps that leverage data from the MTR.
Our APIs support Android, iOS, Windows and Linux development. Platforms supported include Xcode, Android Studio and Visual Studio.
Our open-source APIs are available in Swift, C++, C#, Java, and Javascript. Additional documentation, tutorials, and free example Apps are available.
