Cloud Topper
Screenshots
Description
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.
What's New
Added multiple rotation support. Automatic calibration. Full screen support.

User Reviews
I use this app weekly to determine tops of cells and required altitude to clear a buildup or cloud bank. It does require correlation between radar/stormscope info for best accuracy. NEXRAD works in a pinch.
I haven’t found this useful at all. No clear instructions on how to calibrate or where to put the lines.
This app is difficult to close. Locked up my I pad during flight. Had to reboot and bring ForeFlight back up. Not a good problem to try to solve while in flight. Had to hand my iPad to passenger to solve the problem. I should have practiced first and I would have know not to use this app while in flight.
I deleted it immediately, and wish I could get my money back. Two big problems: 1) once the app is opened and you grant camera access, you can’t swipe up and kill it or switch apps. I had to force reboot my phone to get back to the app switcher. 2) it requires you to know the distance to the cloud you’re measuring “using RADAR”. Like I have that?!
Not very accurate. A small error in angle is a quite large when looking at a cloud which is miles away. This app consistently indicates I will fly into a cloud when in reality I clear it by seventy hundred feet.
Works well as a better refined guesstimator than the naked eye. It would be great if the artificial horizon had an option to always display at 0* and move on the screen relative to the phones actual angle... would be great for measuring in light chop.
Camera functions work, but you can't enter distance to get height. 99 cents down the drain. Worthless don't buy.
It works as advertised. I checked it against TCAS traffic and the altitude was spot on.
Great little tool. Lots of other uses too
Like cloud topper but how would one know the miles to the cloud?
