    Quash▲151

    Hey HN, I’ve been working on Quash, a mobile-first QA tool where you can write test flows in plain English and have an agent execute them on real Android devices. We’ve finally shipped a downloadable desktop app (macOS, Intel + Apple Silicon), and you can try it now. No managed “demo” environment – it runs tests against your own apps and devices. (Can connect any device locally as well)
