A test device concurrency determines the number of devices you can use simultaneously. For example, with 5 concurrent devices you can test 5 different device configurations in the same amount of time it would normally take to test 1.
We measure usage in device hours, which is a calculation of all activities on a device initiated by your test. For example, a 12–minute test suite run on 5 device configurations will consume 60 minutes, or 1 device hour. Time spent downloading apps, processing screenshots, and generating test reports does not count as billable time.
Send an unlimited amount of push notifications to all your users at once for free with the ability to target 5 audience segments. In case you need to target more audience segments, just pay $10 per 100k monthly active devices.
For example, your app has 200,000 monthly active devices and you need to send notifications to more than 5 audience segments, you would pay $20 USD monthly.
