Review of IDA Pro powered by the Slant community.
IDA Pro is a multi-platform application and can debug locally or remotely (Windows 32/64-bit, Linux 32/64-bit, OS X x86/x64, iOS, Android, etc.). This can be carried out either locally or remotely.
There seems to be an older version that's free for non-commercial use.
