News of the lack of a native YouTube iOS app received a lukewarm reaction from consumers. The removal of the long-running iOS YouTube app is due to the end of a deal between Apple and Google, the same reason Apple also launched its map service "Maps" to replace Google Maps.

CouponCodes4U, a large coupon code site in the U.S., conducted the survey and began by asking respondents if an iPhone is owned, International Business Times reported. Among the 2,136 respondents aged 18-30, sixty-seven percent answered yes. Fifty-one percent own an iPhone 4S, 39 percent have an iPhone 4, and just 8 percent own an iPhone 3GS.

Sixty-three percent of the iPhone owners use the YouTube app; 41 percent of the YouTube users said the iOS app is used over 4 times a week.

The respondents were asked about the relationship between Apple and Google. Forty-one percent felt that the rivalry is causing a "negative" impact on customers and developers. Also, 39 percent of the respondents said that Apple is "overstepping" the mark by not using Google Maps and YouTube.

"As the competition between Apple and Google heats up, consumers are likely to see more and more apps fall by the wayside as these two tech companies try to out-do each other," CouponCodes4U Chairman Mark Pearson said. Pearson also expressed surprise over Apple dropping YouTube from iOS.

Google-owned YouTube said it is developing an app for iOS, which will be subject to Apple's approval. As the news broke, a TechCrunch interview at Google failed to get information on whether a YouTube app is in development.

Apple unveiled its Maps service at WWDC in June. It brings Siri-assisted turn-by-turn navigation; search results come from Yelp and TomTom. Live testing may be the only way to see how accurate map results are.

iOS 6 launches this fall. It brings new apps including Maps and the card-collecting Passbook. Certain consumers hope that Apple will unveil a refreshed iOS UI, having used the grid-based app layout since the original iPhone's debut in 2007, especially in light of the open-source nature of Android and the refinements in Android 4.1 Jelly Bean.
