Yes.. developers might prefer android over iOS.. but end of the day iOS apps get you business..IMO...tell me which android apps sell better than their counterpart iOS apps?
Because some niches are really poorly covered on Android, apps that fill those may have greater success than they would on iOS.
Software-savvy giants like Apple, Microsoft, Google and Amazon pretty much don't care about stomping on your little niche (esp. if it's due to a deficiency in the platform/system) if it helps them one-up their competitor.
