Short answer
The Open Measurement SDK (OM SDK) is an IAB Tech Lab software development kit that gives third-party verification vendors a single, standard way to measure viewability and verification in mobile apps and connected TV. Instead of integrating many vendor-specific SDKs, app publishers integrate one, reducing app bloat and enabling consistent independent measurement.
