## What is EvapCoolCalc?

This app uses your location to determine the local weather conditions, and what a properly working Evaporative Cooler will provide for cool air. Based on the local forecast, this app also projects the indoor temperature for the day. You don't have to doubt if your cooler is working properly, now you can check its efficiency with this convenient utility. 

In addition, this utility will give you a local weather forecast and show weather alerts for your area. This app is perfect for desert environments where Evaporative Coolers (Swamp Coolers) are the primary means of cooling a building.

### 5/5 — Just what I needed

*2019-08-07, version 1.4.3*

This simple well-designed app helps me easily decide when I should turn on my swamp cooler and when it would just heat up the house.  I only wish that the biggest number on the screen was the temperature I can expect from the swamp cooler instead of the outdoor temperature.

### 5/5 — Use with Apple Watch?

*2019-05-26, version 1.4.3*

Great and very useful app. Especially when I’m working in my Phoenix hangar in the summer. However it would be great to access it on my watch without finding where I left my iPhone.

### 1/5 — Inaccurate temperature estimates

*2018-08-22, version 1.4.3*

The predicted EvapCoolCalc is inaccurate. The ap predicts temperature much lower than what is actually produced by any cooler. Add 8 degrees to the displayed value and it will be close to actual.

### 3/5 — Weather Forecast in Incorrect

*2018-05-11, version 1.4.3*

Would be a useful app, however, the weather temperature and forecast are incorrect. Perhaps they are from another region?  Does not correlate with my area’s temp. and forecast (El Paso, TX). Please fix.
