Iphone Ballistic program angle finder option???

[Brambles]

I have both Ballistic FTE and Shooter, both of them have angle finding options where you just tilt your Iphone up to the target and capture the angle to insert into your ballistics program.

Are these accurate? Is there any reason to have a ACI or ADI on your rifle if its already part of the program?

Thanks

I use Ballistic on my iPhone as my primary ballistic computer in the field. My iPhone inclinometer is off about 4 degrees. Plus it's awkward to use that way. When shooting I use an inclinometer attached to my scope.
