• One API and one test suite for both platforms, in the language you already use.
• Every device cloud supports it, so you stay portable.
• No modification to the app under test — you test the same binary you ship.

• No SDK and no code — a designer or PM can record a regression flow.
• Self-healing keeps recorded flows working across releases.
• Runs on every build without device lab management.

• Notoriously slow and flaky compared to the native frameworks it wraps.
• Setup is a genuine project: drivers, Xcode, provisioning, Android SDK, versions.
• Debugging failures across the Appium/driver/device layers takes real expertise.

• Limited support for complex logic or data-driven scenarios.
• Cloud-only.
• Now part of Tricentis, so roadmap independence is uncertain.

Teams that must cover iOS and Android from a single suite and can absorb the setup cost.

Small mobile teams needing regression coverage without hiring for it.
