The metric that actually scales your invoice.
Pay-as-you-go on the Blaze plan, billed to the nearest minute. Physical devices cost five times virtual ones, which is the number that actually shapes a bill. Android Device Streaming is separate: 30 free minutes per project per month, then $0.15 a minute.
Enterprise quote-based licensing.
Free tier
Spark plan: 10 virtual-device tests a day (up to 60 free minutes) and 5 physical-device tests a day (up to 30 free minutes).
