Turn classmate feedback into one first change, not a feature list

When a student hands over several testers' feedback and asks for one first change, look for the confusion the comments share instead of fixing each complaint. Here three testers each misunderstood a different screen (how an SOS reaches help, what a status screen's buttons mean, what a relay tab is for), and the common cause was that the app explained itself only in slides shown before the first screen. A guided walkthrough that points at the real controls fixes all three. In an emergency app the walkthrough must never block the real action: it should never tell people to tap the live send control, a real tap should still go through and end the walkthrough, and it should use an existing practice mode that sends nothing. Make it replayable from Settings so the developer can restart it before handing their own device to a tester.
