The CALERAresearch app will continue to offer the features of the old CORE app. This app best suits researchers and B2B customers who require access to high-resolution raw data or simply want to see the live measurements without the bells and whistles of the new CORE app. For customers with logging mode access that want to control multiple devices simultaneously, we recommend using our PC/Mac software (the COREtool) that can be downloaded from the research download portal. (Password is available to customers). More information.
