"Traditional advertising methods (e.g. AdWords) typically don't work cause app prices are too low."
Have you gauged the efficacy of advertising on directly applicable sites, such as (for games) TouchArcade?
I can easily see the low unit pricing being a hindrance - I suppose therein lies the temptation to bolt on IAPs, which opens an entirely different can of worms.
Yes. Not on TouchArcade (since I don't sell games), but I have paid for advertising on AppAdvice and CultOfMac. It seems to be roughly break even for me, but since I can't correlate click-throughs with purchases I don't really know for sure - and experimenting is not exactly cheap.
