Device Tiers


This document outlines the devices we provide, and the tiers we provide them in. Tiers limit the maximum number of parallel tests an organization can run on a single device type e.g. iPhone X on iOS 11. These tiers are applicable to Browser and App Automate.

Current List of devices and their corresponding tiers

Listed below are maximum number of parallel tests we support for each Tier, and the Device-OS combinations which fall under each Tier.


Note: We derive tiers and their values based on the popularity of a device in the market. We also periodically update our tiers based on market trends and usage trends on our platform.
