Cloud Topper vs SkewTLogPro Usage & Stats

Pilots, it's time to get rid of your sight level, water bottle or whatever "old school" method you have been using to determine cloud height. Introducing Cloud Topper, a revolutionary new sight level designed specifically for the iPad and iPhone. With Cloud Topper you can use your device camera, gyroscope and accelerometer as a traditional sight level. Plus you can enter the distance to a cloud and Cloud Topper will calculate your height above or below that cloud. The displayed cloud height is even corrected for the curvature of the earth. Cloud topper is a fun, easy to use app that should be included in every pilots EFB. Cloud Topper is not an FAA approved source to determine cloud height. Cloud Topper is not intended to replace weather radar or pilot skills and judgement. Always consult the Aircraft Manufacturer’s Aircraft Flight Manuals, Federal Aviation Administration (FAA) websites and publications, and individual company policies.
