## What is Rattlewise?

Find the rattle. Fix it. Prove it's gone — all on your iPhone.

Rattlewise turns your phone into a buzz & rattle source-finder for cars, EVs, vans, and homes. Sweep a tone to make the rattle resonate, watch it lock onto a live spectrum, then get a ranked "press here / tighten here" checklist — the step every other app skips. 100% on-device. No account. No cloud.

▸ FIND THE BUZZ
Make the rattle reveal itself, then see it on a live graph.

• Frequency sweep — play a tone that makes loose trim, panels, and clips resonate
• Live FFT spectrum — the buzz shows up as a peak you can actually see
• Peak lock — the app tracks the exact frequency, even for intermittent rattles
• Accelerometer confirm — press your phone to a panel to feel which part is buzzing

▸ KNOW WHAT TO FIX
The part rivals leave out: turning the graph into a plan.

• Ranked likely culprits — plain English, with a confidence level for each
• Guided checklist — press here, tighten here, add felt tape, reseat the clip
• Honest by design — "likely culprits, ranked," never a fake guaranteed diagnosis
• Re-measure prompts — check your work after every adjustment

▸ PROVE IT'S GONE
The shareable proof no free tone generator can give you.

• Before/after report — overlaid spectra with the quantified drop: "peak −14 dB at 280 Hz"
• Share as PDF or image — settle it with a spouse, a forum, a mechanic, or a buyer
• Vehicle & space log — every buzz you've found and proven fixed, per car, van, or room
• Export PDF / CSV — keep your own maintenance record

▸ PRIVATE & OFFLINE
Your microphone audio and motion data never leave your iPhone. No account, no sign-up, no backend, no tracking, no ads. Works fully offline.

▸ WHAT IT IS (AND ISN'T)
Rattlewise is a stationary cabin/room rattle finder — use it parked, never while driving. It surfaces likely sources, ranked by confidence; it is not a lab instrument or a guaranteed diagnosis, and makes no safety or medical claims.

▸ PRICING

FREE:
• Live FFT spectrum + peak tracking
• Guided tone & frequency sweep (the full resonance trick — never paywalled)
• One live "find the buzz" session at a time
• Diagnosis preview (top likely culprit)
