Really helpful

I check this before every flight if weather is it all questionable. Helps find cloud tops, risk of ice, and thickness of icing layer. Have been using it about six months. But still not facile with it. Sometimes is perfect. Sometimes understated risks. I must read more about its use.

Great tool for pilots!

This app is a really good tool for telling you what to expect with regard to current weather, and can help you improve your own forecasting. Using this app and learning enough to be able to understand all it has to offer ought to be part of being a pilot.

It's really fun to look out the window at any time of day, estimate the height of the clouds I see, and then get on SkewTLogPro and use the graph to see how close I estimated. The graphs always match the ceilings given by the 3 airports near here.

And the app's charts are a whole lot easier to read than NOAA Skew-T charts.

Outstanding information for All pilots

Once you spend time to learn how to use a ‘Skew-T’ chart, this app is quick and easy to use and could easily save your life. You can quickly see where the cloud layers will likely be, where you will probably run into to turbulence, and more importantly, where you will likely run into ice. Yes, you can get the data from other sources (NOAA, and where this app draws its information) but not as easily as this. Thank you for the great app that makes flying safer!
