Basically a great idea...

because it's difficult to estimate if high enough to get over the clouds at altitude. Of course you can't use this app for measurement. But for any reason not even bearing really works. It's hard to find exactly 0 degrees but even then the app seem not to show straight level ahead.
Maybe some improvement and more testing, then it could be a really helper.

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.

Useless

I haven’t found this useful at all. No clear instructions on how to calibrate or where to put the lines.

Hello J N C C, You can go to our help page at http://www.cropapplications.com/CloudTopper/help.htm for instructions to use the app. Please email us with any questions you have and we will get back to you right away. Happy Flying!

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.

Response from developer

Hello Old Rancher Dude, The older versions of Cloud Topper only has support for landscape orientation. This could make the app confusing to close if you were holding the device in the portrait orientation. Our newest release has support for all orientations. To close the app, simply swipe up from the bottom of the screen like you would with other iOS apps. Hops that helps.

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?!

Hello TXPilot69, 1) The app is oriented in landscape mode so you have to swipe up from the bottom when in landscape (you could also swipe from the left side, on the white bar, if holding your phone normally). This is the case for any app that is landscape orientated. The reason for the orientation is that the app uses you phones angle to work correct. If you continue to have issues with the app, I suggest emailing us and we will fix the issue. If we can’t fix the issue we’d be happy to send you a full refund of 99 cents. 2) If you don’t have weather radar, you can make an estimate of your distance to the cloud. You can also use the angle to determine if you are above or below the cloud. I suggest you get an app like ForeFlight and an ADS-B receiver to display weather radar. If you are in an airplane that doesn’t have an onboard weather radar, I’d suggest not trying to fly over the top of any convective activity. If you have another suggestion of how to determine the distance to a cloud through an app, we’d love to hear it.
