There's lies, damn lies and then there's App Store ratings!
If the hall of fame is anything like the way Apple rates apps in the app-store in general then it will contain susprises that nobody can fathom...
... e.g. 'Phone Tracker Spy Pro' is on #13 in the 'Top-25' app-store apps (was #10 at the end of last week). This presumably is due to the large number of downloads of this (non-free) app?
However, the * rating is currently 3 out of 5 (was 4.5 out of 5 last week). This is totally misleading as almost all of the 1000+ user ratings give the app one or zero stars and all are contain negative comments about a fake/joke app this is mis-sold as the app description ends "It works - Guaranteed!" - and nowhere does it admit to being a fake/joke app.
Apple appears happy to take their share of the £0.59 purchase cost everytime some (dumb/trusting) user downloads this horrendous app.
So how does Apple's Top-25 and * star rating work? I suspect an app is awarded the max 5 stars for every download, and this is only reduced if the purchases chooses to rate it afterwards. VERY MISLEADING. Naughty Apple!
