Is there a way to determine if an App is running on Intel or PPC
from within the App?

Depending on what you're trying to do, you can go at least a couple routes at build time.

If you only care about endianness:

#ifdef __BIG_ENDIAN__
#ifdef __LITTLE_ENDIAN__


If you care about the actual architecture:

#ifdef __ppc__ 		// 32-bit PPC
#ifdef __ppc64__	// 64-bit PPC
#ifdef __i386__		// 32-bit Intel
#ifdef __x86_64__	// 64-bit Intel

There are also parallel ones defined in /usr/include/ TargetConditionals.h:

#if TARGET_RT_LITTLE_ENDIAN
#if TARGET_RT_BIG_ENDIAN

#if TARGET_CPU_PPC
#if TARGET_CPU_PPC64
#if TARGET_CPU_X86
#if TARGET_CPU_X86_64
