Why Cool Cue exists
I’ve lived 45+ years with and without AC.
Without AC, everyone knows the move: open the windows at night and let the cool air blow through. The problem is the morning. You’re enjoying how good it feels — and the next thing you know, you’ve enjoyed it too long. The day warmed up, the house warmed up, and now you have no choice but to leave everything open and take what you can get.
Cool Cue is the reminder I needed: close up while it’s still cool. Windows shut, blinds down — sunlight entering your home is the enemy. Contain the cool, and it can carry you deep into the day.
And with AC? I’m guilty too — running it all night against a warm roof when the outside air has already cooled down and it’s free. Open up at night, close up in the morning, and your AC might not need to kick on until much later.
It’s not just homes.
I’ve been in warehouses with large doors open when they should be shut, and shut when the air outside was already cooler than the air inside. I’ve been in restaurants with whole walls of open windows. Just like at home — push it too long and the building gets hotter than the AC can fight. That’s how units ice up and quit.
Multiple situations. One habit. That’s Cool Cue.
Cool your home with the night air.
Cool Cue watches the forecast and tells you when the outside air has turned cooler than your house — so you can open the windows in the evening and let the night do the work. In the morning it reminds you to close them again, before the day warms up.
Evening
Open your windows
At sunset, or at a time you pick. Cool Cue shows you tonight’s real hourly temperatures so you can see the drop coming, instead of guessing.
Morning
Close them again
At a time you pick. Shut the house, all blinds and windows, before the day warms up and hold on to the cool you collected overnight.
It stays quiet on cool days
You set the temperature that matters to you. Cool Cue only sends reminders on days when the forecast high actually reaches it — so a mild week passes without a single notification, and you are not training yourself to ignore it.
Then choose when it reaches you. The nightly open reminder can follow sunset — the point the day actually starts giving its heat back — or an hour you pick yourself. The morning close reminder gets its own default hour. Each picker sits directly under the real hourly forecast, so you can see whether an earlier or later hour would serve you better before you choose.
- Pick your own trigger temperature
- Type in your town — anywhere in the world
- °F or °C, 12-hour or 24-hour clock
- Open at sunset, or an hour you choose
- Set your default morning close time
- Set it up once and close the app
You set the temperature, for days you want alerted on.
Then choose when you want the reminders to alert you.
The real numbers, not a promise
Cool Cue shows you the actual hourly forecast for tonight and tomorrow morning, and the highs and lows for the next eight days. It tells you what the air is doing and leaves the decision where it belongs — with you. On a night that will not cool down, it says so plainly rather than telling you to open the windows anyway.
A heads-up before a hot stretch
When a run of hot days is coming, so you can plan, Cool Cue tells you at the start of it — not on the third afternoon when the house has already stored the heat. It names the days, shows the highs, and reminds you to check on the people nearby who may be struggling with it.
And when it turns cold
Cool Cue also watches for a freeze in the eight days ahead. If one is coming, it sends a reminder and opens a short preparation checklist — pipes, outdoor taps, pets, and a plain safety warning about heating a home with anything that burns.
What Cool Cue does not do
Plainly, so there are no surprises:
- It does not know where you are. You type your town in. There is no GPS and no location permission.
- It does not track you. No accounts, no advertising, no analytics, nothing sold. Everything stays on your phone.
- It only measures temperature. It does not monitor air quality, smoke, humidity or pollen — check those yourself before opening up.
- It does not control anything. No thermostat, no smart devices. It sends reminders; you decide.
- It cannot promise a reminder will arrive. Phones get switched off, silenced or lose signal. Please do not rely on it as your only warning.
- It is not a safety or emergency service. The freeze reminders are a convenience, nothing more.
Only you can judge whether it is safe to open your windows. If you cannot open up and cannot stay cool, please seek help.
