European summer, no A/C? Ventilate helps you open window by window at the right hour, close before the heat returns, and use a fan well. If the last few days have left you drained, sticky, and unsure what to do with your windows, you are not alone. When the heat won t let go, every choice feels heavy: open and let warm air in, or close and trap the warmth you already have. Ventilate is a calm guide for exactly that moment. It looks at your local weather, your indoor temperature, and each window in your home, then tells you when to close, when to open, and where to place a fan so cool air actually reaches you. No lectures, no guilt, just clear next steps when your head is too foggy to guess. Built for real heatwaves Per-window advice: close, crack open, open wide, or fan placement Timing that follows the weather, not the clock Fan guides matched to your layout (single-sided or cross-ventilation) Gentle reminders before the next change Heat toolkit: cool yourself, protect windows, and more Set up once, then breathe Point your phone at each window so the app knows which way it faces and what is outside. Add your indoor temperature when you can. A thermometer helps, but you can start without one. When the evening finally cools, Ventilate helps you catch that window, before the heat builds again tomorrow.
