The ideaWhat this actually is
A wellness app that passively counts coughs (on-device, audio never leaving the phone) and correlates patterns with environmental context like air quality, pollen, weather, and user-logged factors, turning an invisible symptom into a chart a doctor can use. It is a general-wellness tracking tool, not a diagnostic device; its hero artifact is the doctor-visit report, and it points users to a clinician for diagnosis.
The opportunityWhy this idea works
Chronic cough is one of the most common reasons people see doctors, and the clinical conversation runs on the worst possible data: how often would you say you cough? Nobody knows; they were asleep for half of it. Phones can already count coughs acoustically on-device, and the context that makes counts meaningful (air quality, pollen, humidity, the new detergent) is loggable or fetchable. The quantified-self wave skipped the symptom that parents of coughing kids and chronic coughers would track tomorrow, and the doctor-ready report is what they will pay for.
The openingWhy this idea is overlooked
Quantified-self products chased steps and sleep, not cough, so a symptom people would eagerly track was skipped. On-device acoustic cough counting is newly practical. And doing it responsibly means on-device audio processing for privacy and staying in the wellness lane rather than claiming diagnosis, which is more careful work than a generic tracker.
The buildWhat you need to build this
| You need | Why it matters |
|---|---|
| On-device cough detection | Counting coughs acoustically with audio never leaving the phone is both the core feature and the privacy guarantee. |
| A nighttime mode | People cough most when asleep and know it least, so nighttime counting captures the data they cannot report. |
| Environmental correlation | Air quality, pollen, humidity, and logged exposures are what turn raw counts into meaningful trigger patterns. |
| A doctor-visit report | The hero artifact is a clear report that turns an invisible symptom into a chart a clinician can use. |
| A wellness-not-diagnosis line | Staying in general wellness and pointing to a clinician keeps the app honest and out of regulated device territory. |

Questions
What people ask about this idea
Does this diagnose why I cough?
No. It is a general-wellness tracker that counts coughs and correlates them with environmental context, then produces a report for your clinician. Diagnosis stays with the doctor.
Is my audio private?
Yes. Cough detection runs on-device and audio never leaves the phone, which is both the privacy promise and the trust the app depends on.
Why track the environment too?
Because raw cough counts are noise without context. Correlating with air quality, pollen, humidity, and logged exposures is what reveals the triggers.
What is the main value?
The doctor-visit report. It replaces how often would you say you cough with a real chart, especially for the nighttime coughing people cannot report themselves.
