Theres often a disparity in price between consoles an iOS/Android. This is likely because no one would buy a 15$ iOS game because they have been spoiled by $1/Free content. $15 in this case would be the Regular Price of the game with iOS essentially being discounted right off the bat.
Also, third parties set their own prices, can initiate sales and drop the price of their content on the eShop if they want. That isn't Nintendo's decision.
