App stores should provide a graph showing expenditure marking the [expected] average and SD per fixed time division (month say), that would be one of the least deceptive and least customer hostile ways to present IAP apps.
Examples:
* Game costs average $1 per month, SD 20¢; OK cool.
* Game is "free" costs average of $20 per month, SD $5.
* Game is free. Average $0 per month.
* Game is 99¢ fixed. Average $0 additional per month.
Even better they could give a playing time [weighted average] too. Then you could compare:
* Game is "free" costs average of $20 per month, SD $5; $1 per hour of play.
* Game costs average $1 per month, SD 20¢; $2 per hour of play.
Seems about as likely as getting the supermarkets to clearly display the cost per kg of all food items.
