qckfx records what you're already doing. You tap through the simulator to check your work, and it replays those sessions to catch visual regressions and crashes. No SDK, no code changes, no test files.
How it works: finish a feature, click around in the simulator, hit Cmd+Shift+S. That's your test. Cmd+Shift+T to run it before you push.
It's free, runs locally, and installs via Homebrew: brew install --cask qckfx/tap/qckfx. I'm a solo dev (10 years iOS, ex-Meta) and this is early. Feedback welcome.
