Legitimate biometric palmistry apps available?

Was wanting to check out different biometric apps on my iphone, but they mostly false advertise and say in a tiny disclaimer at the bottom that the scan does not actually do anything, entertainment purposes only, or the best ones say something along the lines of a joke reading sent to you so you and your friends can laugh and post to Facebook! I don't take astrology, tarot, and palm reading that lightly. Any links or recommendations?

Nothing with Tarot would work well with apps. You'd need to use your own deck.

  • Why many Iphone apps aren't available internationally? Why many Iphone apps are not available internationally? I live in Finland and I use of course Finnish Appstore. But I can't download many apps I'd really like to get (Metacritic's, GameSpot's and Eurogamer's Iphone applications for example).It seems that they are only available in US Appstore. Is there any way to get those to Finnish iDevice? There are many more examples, I just named a few.

  • Why are some apps only available in android and not on iphone? My boyfriend has iPhone and I have an Android. The other day, I wanted him to download a game that I have so we could play together.

  • Why are new apps always available only for iPhone? I use an Android smartphone. EVERY TIME I see a new app I'd really like to try, it's only available for iPhone. Or it says "coming soon for Android" but soon never happens. Is this because it's cheaper/easier for developers to create for iPhone?
