The Most Powerful Software

Free MetaBase App on Android, Windows, 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 MMC.

Develop Your Own Apps

Use our developer tools to build your own App.

Develop Apps that leverage data from the MMC.

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.

Your Data Anywhere

Easily access and analyze your raw data with our Cloud

View and manage your data on our secure Cloud platform; available for a monthly fee.

You can also download raw data in CSV format for easy processing and analysis in third party applications.

Your data is secured with encryption. One login means you can access your data any time, anywhere.

For developers, data can be downloaded in JSON format via our Javascript API layered on top of our RESTful interface.
