AirScore – Personalized Air Quality Alerts

People with allergies or respiratory conditions need air quality info tailored to their specific sensitivities, not generic AQI numbers. AirScore sends daily emails with air quality data customized to household conditions (pets, kids, health issues). Target users are health-conscious families and people with asthma/allergies.

Wearables and chronic disease management have pushed consumer health awareness to a genuine high, and post-COVID sensitivity to air quality and respiratory health is measurable in search trend data — so the audience exists. IQAir and AirVisual already offer location-based AQI apps for free, which sets a tough baseline expectation and makes paid email alerts a hard sell without a compelling personalization story. The $300–1.5k/mo revenue band is realistic only as a bootstrapped side project, since the low willingness-to-pay in consumer health (especially for something perceived as a notification service) caps subscriber count well below what sustains a real business. The most likely failure mode is that users find the free alternatives "good enough" and churn before the personalization layer proves its value.
