What’s New Version 1.63
Added multiple rotation support.
Automatic calibration.
Full screen support.
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.

Great, simple tool
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.
Flabbergastibulator2022-12-15
★★★★★
Useless
I haven’t found this useful at all. No clear instructions on how to calibrate or where to put the lines.
J N C C2021-08-26
★★★★★
Wasted 99 cents.
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.
Old Rancher Dude2020-09-07
★★★★★
Awful
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?!
TXPilot692019-03-23
★★★★★
Not accurate
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.

Useful, Not Perfect
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.

Doesn't work
Camera functions work, but you can't enter distance to get height. 99 cents down the drain. Worthless don't buy.
Mgustin20082015-06-13
★★★★★
TCAS Tested
It works as advertised. I checked it against TCAS traffic and the altitude was spot on.
Random Dent2013-09-30
★★★★★
Limited Orientation
This app only works in landscape with the power input on the right. I find this annoying. It is also unclear how to use the miles function and there is no help function. Nice first try, but needs more refinement.
nvpatentlawyer2013-02-15
★★★★★
Needs a calibration feature
Apparently my iPad's sensors don't exactly match my camera's centerline resulting in this app being a little off. I wish there was a way I could "zero" the app at a true level.

Great! Way better than the sight glass we used on the tall ships.
Adds another method of ensuring weather avoidance. Also just plain fun!

Crack
This app changed my life. Before cloud topper, I was not able to top clouds. I was an old fashioned crack in the seat. Now I look like I know what I'm doing. Thanks Cloud Topper!!

Shweeet!
Throw those water bottles in the recycling bin.....this app is the way to go to clear those cloud tops!

Brilliant!
This app lives at the intersection of fun and useful. Great for passing time on cross countries. I recommend it to all my pilot buddies.

Very helpful
I am an aspiring pilot, and this app gives me great insight into how to avoid severe weather while flying. I'm excited to use this in the air!
Wannabe Flygirl2012-10-25
★★★★★
Innovative!
Wish this came out out in 1970 when I started flying. A much needed update to my old "water bottle" technique. May have kept me from being struck by lightning in December of 2002!

It works!
What a great tool for the flight deck; ANY flight deck, from a 172 to a 747. For less than a buck? Why WOULDN'T you have this tool at your disposal?!

I love this app!
So cool! This app makes me feel like a real pilot using the same tools inflight!

Great addition to any flight bag!
Does just what is says and then some! Been looking for an app like this for quite some time and its finally here! Thanks for the great addition to the App Store.
