About MobileBoost
MobileBoost is an AI SDET for iOS and Android apps. An agent turns a plain-language test spec into test code, runs it on simulators and real devices, and fixes it when your app changes. Nobody on your team maintains test scripts by hand. The test code is accessible at any time if your team wants that level of access. You can start runs from your CI pipeline with the MobileBoost GitHub Action, or let your coding agent start them over MCP while you build. Mobile teams at Duolingo, Lyft, Wayfair, Flo Health, Noom, Compass, and Redfin use MobileBoost. Duolingo cut manual regression testing by 70%: https://blog.duolingo.com/reduced-regression-testing/
