Horizontal Pro
This app’s attitude indicator incorrectly showing the bank. It seems there is no way to “calibrate” the attitude indicator to compensate the iphone’s orientation. Given that, not sure why this app was developed.
App needs a lot of help
Compass is very inaccurate, device needs to be set at about 30 degrees from horizontal for artificial horizon to read straight and level, altimeter shows device is at sea level rather than actual 3400 ft ASL, VSI is all over the map unless device is lying on a flat stable surface. No idea if the “air speed indicator” works or not. Too bad this app doesn’t work; the graphics look real good.

Not working correctly
Heading has about 90 degrees error, vertical speed needle vibrates a lot
If any pilot were to use this, they could die
Please DO NOT use this app for ANY flight operations.
Let me count the ways that this app is dangerous and doesn't work:
1. VSI bounces around randomly when stationary.
2. Artificial horizon doesn't track the horizon when yawed.
3. Relies on GPS for altitude when GPS maybe off by ±100 feet in the vertical component due to triangulation error when the satellite constellation is in an "most satellites above" "fix" pattern.
This app is more of a liability than useful for even toy demonstration purposes. It should be pulled from the App Store.

Doesn’t work at all
Why do none of these sort of apps work, they are so easy to make.
None of the instruments work, this app should not be on the App Store it has no function
