Designed by an airline pilot, Spin-a-Wind calculates wind components, temperatures, altitudes and airspeeds.
The headwind (tailwind) and crosswind components are based on the runway, and reported wind direction and speed. If the airport has parallel runways, using the runway number closest to the actual magnetic heading of the runway gives the most accurate results. The result is also displayed graphically. Crosswind and tailwind components are rounded up, while the headwind component is rounded down, making sure that all results depict the worst case. To instantly change to the opposite (reciprocal) runway, tap the runway number at the far end.
Spinning reels are used to make your selections. No keyboard is necessary. Results of calculations are displayed instantly when the last reel stops. The app was designed for one handed use, and ease of operation.
The second item on the tab bar links you to a page with temperature conversions. Enter the temperature in degrees Celsius, and instantly the Fahrenheit conversion is displayed, as well as the chill factor in °C and °F using the NWS Wind Chill index used by the U.S. and Canada. (note: the NWS Wind Chill index is not valid for greater than 50°F or less than 3 mph of wind. Relative Humidity and Heat Stress Index are calculated using the entered Dewpoint Temperature.
The third item deals with altitudes, metric, pressure altitude and density altitude. Density altitude is diaplayed for assumed dry air, and also moist air (based upon the temp/dewpoint spread entered in the temperature page.
The fourth item is the Airspeed Calculator. It uses equations for TAS, mach, and speed of sound. The equations used will be accurate even for the higher speeds of jet aircraft.
The fifth item on the tab bar moves the view to the settings page. Here, you can set your display speed units (kts, mph, kph) and pressure units(inHg, hPa, mb) as well as the threshold points where the wind results turn amber (caution zone) and red (aircraft limits).
Ok, for the constructive criticism ...the graphics are a little cheesy. We don't need the lined paper look or the textures, but this app has everything necessary. The size of some of the graphics may seem large (note to developer: NEVER change the size or functionality to something slick ...just lose the colored textures). I used this app today while flying in turbulence on an iPad mini. The conditions were gusty and even while bouncing around I was able to quickly and efficiently determine my crosswind component. I have since explored this app further and set caution and limit wind values for my aircraft. I am not into emojis, but two thumbs up for this app.

Great program! When checking the winds for TO or landing, and their are winds of any speed I always check for headwinds and especially crosswinds. I have the aircraft’s demonstrated crosswind speed set for the yellow zone and my limits set for the red zone. Very helpful safety check. Please keep updating this program for newer operating systems. I want to keep using it. Thanks for the App.
Great font size!

Easy to use and interpret display. I use it on iPhone and iPad. The wind function is the best I've tried. I wish you could have a few choices for color options, especially on the wind page.Also, it really needs a night mode.
Upgrade
no name 5239n
Love the app use it often I wish I could move it to split screen on the new ForeFlight App5230NIf it were upgraded to work with ForeFlight split screen ie would pay for the new version.
This update from Apple will improve the functionality of this app. No new features are included.
Updated code and design to iOS 8. Redesigned Info/settings page. Added user selection for wind direction arrow (like weather vane), or wind vector arrow (like wind sock).
Version 2.7.1
