If you live in a dry, arid climate and use a whole-house evaporative cooler to stay cool, it's sometimes hard to know when it'll actually work! Sometimes it's fine in the morning, but too humid or hot out later in the evening when you'll need to run the A/C. This app helps you plan ahead to know when the weather conditions are favorable for running your cooler.
This app provides:
* An easy-to-read dashboard, showing the indoor temperature and indoor humidity that your cooler would produce, right now.
* Your forecast for the hours and days ahead, to know when and how long you can use Cooling mode. Or when you could switch to Fan mode for extra ventilation. And also importantly, see when the weather won't be cooperative, so you can switch back to A/C before it gets too sticky or hot indoors.
* Your cost($) and energy(kWh) savings estimates from using a swamp cooler vs air conditioning.
* Your historical weather summarized as annual reports of how effective evaporative cooling was, in terms of hours of A/C reduced, kWh saved, and dollars unspent.
* Customizable settings so you can set your own temperature comfort zone, humidity tolerance, local energy rates, A/C sizing and efficiency values, and more. Best of all, when you customize your settings, all of the forecast ahead is updated to show the effects on energy and cost savings.

For fun, you can compare the cooler forecasts from other sites around the world, in the Explore tab. You can see their weather and data to help contrast it with your own, to help keep your expectations in context.

If you don't have a swamp cooler, you can also use the app to judge when to run a house fan, or box fans in your windows, using your personal Fan Mode comfort zone settings.

In short, take the mystery out of running your evaporative cooler with a personalized forecast that tells you what it will feel like both out and indoors.
