My main use case for Genymotion Cloud is to generate diagrams. I work for an oil and gas company, so we use Genymotion Cloud to generate data by utilizing all the data from IoT devices in our platform.
We use Genymotion Cloud for Android virtual cloud devices. We install our application, then execute automated tests. We get the results, then we turn off the devices.
We use Genymotion Cloud for automated Appium, Espresso, and Roboto framework.
