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.

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.

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?!
