So, your app is quite out of date.
If you Google the same actors name in relation to Kevin Bacon for instance ((actors name's) Kevin Bacon number)), Google gives you the correct numerical value of separation between the two.
Your app on the other hand, being out of date, incorrectly associates a number (IMDB was used to verify my above statement).
Please update your app so the money you're charging for it, seems at least moderately tolerable.
