About this app

2lines helps you review line visibility from a test photo using your iPhone camera. Capture or choose a photo, align the result window, and get a clear visual summary of what appears in the image: one line-like signal, two signals, a possible faint second line, or an unclear photo. Everything runs locally on your device.
