• Very cheap per device hour compared with commercial device clouds.
• Robo Test finds crashes with zero test-writing effort.
• Tight integration with Android tooling and Firebase Crashlytics.

• 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.

• Device selection is far narrower than a dedicated device cloud.
• iOS support is meaningfully thinner than Android.
• No interactive manual testing session.

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

Android-first teams that want real-device coverage at the lowest cost.

Small mobile teams needing regression coverage without hiring for it.
