For iOS Developers
You just got pinged off hours — the UI is broken in prod.
The tests were flaky. QA missed it.
No one tested this flow.
qckfx catches UI bugs before you push your PR.
How it works
Record.
Click through a flow in the simulator. qckfx captures every tap, scroll, screen, and network response.
Change code.
Fix a bug, add a feature, refactor, whatever.
Replay.
qckfx runs the same flow and compares every screen to the original.
Diff.
See exactly what changed. Accept the new baseline or fix the regression.
qckfx runs non-flaky, deterministic replays using:
Network replay (VCR)
Stubs all network responses automatically. No flakiness from non-deterministic API responses or timing.
Synced disk states
Copies local data and keychain state. No workarounds needed for auth or test accounts.
Accessibility tree matching
Uses accessibility identifiers and labels where possible, for robust tests that endure layout changes.
Precise scrolling
Scroll directly to offsets rather than using mock gestures.
Built for individual developers.
Free, no account required, no code to commit.
Tests live in qckfx, not your repo.
