ChirpHound: Smoke Alarm Finder

ChirpHound 11.0 makes the search easier to follow and the detector easier to trust. • Guided room comparison: one 3·3·3 sequence — three readings at your reference, three at another position, three back at the reference — with a single progress card that captures each chirp for you and keeps every measurement safeguard • Listening progress: see what the app is doing while it waits — settling, listening time, level relative to the room, band, chirps heard and the predicted next chirp — with one clear next action, so silence never looks frozen • Scan the label: read the model number and label date from a photo, confirm what was read, and open the manufacturer's own support page • Email support: a prefilled draft with the app version, device model and numeric diagnostics that you review before sending from your own mail app • VoiceOver and large text: labels, values and hints across the whole investigation; spoken progress that stays quiet around the expected chirp • Detection: the detector now weighs the whole preset band instead of one frequency, so a chirp a little off its expected pitch is no longer filtered out; the next-chirp clock follows measured cadences up to 5.5 minutes instead of guessing from a preset; long chirps and echo tails are no longer counted twice; a chirp in the first seconds of listening is no longer lost — each checked on a synthetic room, noise and microphone bench that runs with the app's tests • Two new field guides and two new checklist items • 11.0.1: every beep of a rapid alarm burst is counted in an echoey room — a chirp whose echo tail ran to the tracking cap no longer hides the next beep behind the re-arm delay (found and fixed on the bench's full 300-scene run; the 10.0 path is unchanged) Earlier saved searches remain available.
