Ventiloom: CO2 Airflow

Ventiloom: CO2 Airflow is an offline indoor-air workbench for estimating air changes from carbon-dioxide decay, comparing occupancy scenarios, and documenting ventilation observations. KEY FEATURES - CO2 decay-session analysis - Visible logarithmic decay method - Air-change estimate from timestamped readings - Steady-state occupancy airflow comparison - Outdoor baseline and room-volume controls - Editable readings plus CSV import - Sensitivity comparison and uncertainty context - Local PDF analysis packet - Forty original offline ventilation reference plates ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core tools and bundled reference material work offline - Work remains on device unless you deliberately import, share, or export through an Apple system interface Ventilation estimates are informational and are not a health or safety diagnosis.
