That periodic chirp is real. ChirpHound helps you investigate it with a clear path from listening to a recorded follow-up. GET THE ANSWER, NOT JUST THE LOCATION • Chirp Verdict pairs the measured cadence with a short set of plain questions: kind, brand, power type (replaceable, sealed 10-year, hardwired), wiring, whether a new battery stopped the chirp, the label date, and timing. • One card with receipts: low battery, still chirping after a new battery (residual-charge reset), end of life (replace the unit, not the battery), past replace-by guidance, hardwired chain (find the unit on backup power), or a model-specific code. • Sourced fix steps; a three-beep or four-beep safety pattern is never softened. • No microphone needed for the questions: answer from what you know, then confirm with a measured cadence. SCAN THE LABEL • Read the model number and label date from a photo of the alarm's label, on this device, then confirm or correct what was read. • Open the manufacturer's own support page (Kidde, First Alert/BRK, Nest Protect, USI) or the USFA guidance; an exact manual is linked only when the model is recognized. • Manual entry stays available. FOLLOW THE CHIRP • Listen: choose a preset or use Auto Discover; a progress panel shows settling, listening time, level relative to the room, chirps heard and the predicted next chirp, with one next action. • Learn target: learn a numeric fingerprint from repeated chirps to help separate similar sounds. • Compare: a guided 3·3·3 sequence — three readings at your reference, three at another position, three back — captures each chirp for you; changed input, clipping and low signal-to-noise readings still never join a comparison. • Inspect: record the device/model and location you physically observed, your own identification, and any action taken or planned. • Verify: keep the same microphone and target active for a chosen window and record what happens next. KEEP THE EVIDENCE Each capture keeps its input segment, target, band energy, background estimate and exclusion reason. Resume saved searches; export the ledger as CSV or a paginated PDF field report. FIELD TOOLS WHEN YOU NEED THEM • Live spectrogram, 24-band Auto Discover, 15 presets and a next-chirp clock • Manual chirp marks and pattern suggestions • HoundMap checkpoints, EchoMap room observations and optional ChirpMesh nearby sessions • Hearing Assist options for visual, haptic, spoken and headphone cues • Not hearing it? troubleshooter with wait guidance • Email support: a prefilled, numbers-only draft you review before sending • 19 synthetic Signal Lab scenes, 48 checklist entries, 24 field guides and 22 reference patterns (16 cited to standards or manufacturer pages) MEANINGFUL LIMITS Comparisons require one unchanged input and target, repeated readings, and a return to the reference; short chirps may need more readings. The app does not measure movement, calibrate microphones or infer distance, direction or probability. No matching chirp during a timed window is an observation, not proof of repair or safety. A verdict interprets your answers and the measured cadence; codes vary by manufacturer and model, the label and manual govern, and the app never states that an alarm is safe. Label reading is text recognition on your photo — check it against the label. Synthetic-room tests validate the software, not your room, microphone or alarm. PRIVATE BY DESIGN Audio is analyzed live on the device and is not recorded or transmitted. The camera is used only when you tap Scan the label; the photo is processed in memory and never stored or sent. Support email is composed by you and sent from your own mail app. No account, advertising, analytics or tracking. Records stay on the device unless you share a report. ChirpHound is a locating and reference aid, not a smoke alarm, CO alarm, sound-level meter or substitute for emergency action. If a real alarm is sounding, leave the area and follow its instructions. ## Rankings - #969,381 — Overall ## Similar extensions and apps - [BeepDetect](https://chrome-stats.com/d/id6761551923) — 5.00 / 5 - [Sound Finder & Noise Meter](https://chrome-stats.com/d/id6801197845) - [Find Phone by Clap and Whistle](https://chrome-stats.com/d/id6744183290) - [FindThatCricket](https://chrome-stats.com/d/id6759961402) — 1.00 / 5 - [ChirpAlarm](https://chrome-stats.com/d/id6765998921) — 5.00 / 5 - [RADAR – Family Phone Finder](https://chrome-stats.com/d/id6799559160) - [Clap Detector: Find My Phone](https://chrome-stats.com/d/id6746837240) — 4.00 / 5 - [Chirpy: Mission Alarm Clock](https://chrome-stats.com/d/id6782368573) — 5.00 / 5 - [Clap Alarm to Find My Phone](https://chrome-stats.com/d/id6767745101) - [Batteries At Home: Tracker](https://chrome-stats.com/d/id6468886828) — 5.00 / 5 - [DAQIchirp](https://chrome-stats.com/d/id1412530880) — 3.30 / 5 - [Clap To Find My Phone Detector](https://chrome-stats.com/d/id6502971126) — 4.40 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id6777020126)
