Redspira es un proyecto de monitoreo colaborativo de la calidad del aire consistente en una red de monitores de bajo costo para la medición y reporte de distintos tipos de variables relacionadas con la contaminación atmosférica. Uno de nuestros objetivos es concientizar a los habitantes de Mexicali sobre el impacto que tiene la calidad del aíre en su salud y bienestar. Para ello, hemos creado plataformas web como https://app.respira.org/ y https://mapa.respira.org/ así como aplicaciones móviles en las cuales se monitorea en tiempo real la información proporcionada por los sensores Redspira (creados por nosotros), Purple Air (red comercial de uso público) y las estaciones normativas de monitoreo del Gobierno Municipal y Estatal. En el mapa puedes consultar por las distintas zonas de Mexicali los sensores y sus mediciones, expresados de manera muy visual con un código de colores relacionado con la medición. Se utiliza AQI NowCast e Indice Aire y Salud para la notificación de la calidad del aire. Redspira es un proyecto de Certuit Consultores, S.C.

Verdict

The call

The clearest difference is review sentiment: Redspira at 100% against FTN's 56%. Redspira also leads on in-app purchases (none vs 4) and rating (5.0 vs 4.8). FTN's advantage is ratings volume (345 vs 4) and update cadence (every 9 days vs every 4 weeks). On price, ads and device support there is nothing between them.
