• UXUpdated rate-counting hint to advise rotating phone to landscape for full six-second strip view

Original release notes

New: Measure It.

Naming the rhythm is only half the exam. Measure It asks for the rate, the PR interval, or the QRS duration on the strip in front of you, and grades what you type against the strip's own numbers. Not every quantity exists on every rhythm; a strip with nothing fair to measure tells you that, which is itself the finding.

Fixed: the rate-counting hint now says to turn the phone. The strip is six seconds, but portrait only shows about three, so counting complexes in portrait was giving half the real rate.
