"APP" appears to mean "a-posteriori probability" in this context.

They are completely different algorithms.
According to http://stats.stackexchange.com/questions/31119/posterior-probability-vs-viterbi-algorithm
"Viterbi gives most likely sequence, posterior (Forward-Backward) gives most likely state at each position. Which one you choose depends on what kind of errors you prefer -- if you care about the number of sequences you get correctly, then Viterbi algorithm is preferable, if it's the number of individual state errors, then, Forward-Backward is better."
