AirFlow Planner

AirFlow Planner is a fully offline tool for preliminary ventilation calculations. Create room projects, account for ductwork losses, and compare fans based on effective performance, safety margin, and noise levels.

App features:
• Project management: search, sort, duplicate, delete, and undo
• Scenarios: bathroom, kitchen, bedroom, workshop, storage room
• Calculations for volume, air exchange rate, and base airflow
• Duct segments: length, round/rectangular cross-sections, bends, grilles, and dampers
• Transparent, editable loss coefficients
• Recommended rated performance range (accounting for uncertainty)
• Fan comparison based on effective airflow, safety margin, and noise
• Text report for equipment purchasing (via system file picker)
• JSON backup/import with Replace and Merge strategies
• Light/dark themes, Dynamic Color support, metric units, and CFM

Privacy:
• No account or registration required
• No internet connection or ads
• Data stays on your device

Important: This is a preliminary estimate, not a substitute for a professional engineering design or static pressure verification.
