尽管许多人认为苹果发布iPhone 5会重演iPhone 4S出炉时的用户获取成本上升现象（当时为1.47美元），但实际上9月份的忠实用户获取成本已降至1.13美元（游戏邦注：2011年5月份苹果取缔非自然下载措施时iOS忠实用户获取成本为1.1美元，2012年1月份假期结束时这一数据为1.14美元）。

从下载量来看，9月份免费应用日均下载量为407万次，略高于8月份时的405万下载量。在iPhone 5发布之前该月下载量下降了3%，但在该设备发布后（即9月21日）下载量攀升了33%。

Fiksu报告指出尽管10月份的下载量及用户获取成本很可能上升，但总体成本将低于去年水平。

2）据gamasutra报道，亚马逊游戏工作室日前发布其首款手机游戏《Air Patriots》，并将其投放到亚马逊Appstore，以及Google Play和苹果App Store。

该游戏采用IAP模式，以及Whispersync云存储功能和Game Circle成就管理/积分排行榜元素。

亚马逊将游戏发布到竞争对手平台的做法较为罕见，因为任天堂、索尼等平台运营公司一般仅向自有平台独家发布第一方游戏。不过此举更有利于亚马逊游戏团队了解开发者需应对的不同用户体验，并将这些经验用于改善自己的Appstore。

《Air Patriots》是亚马逊游戏工作室发行的第二款游戏，该工作室曾在8月份向Facebook推出《Living Classics》，但并未收获理想成绩，目前MAU仅为14万。

1）Fiksu: Despite iPhone 5 launch, September user acquisition costs fall to lowest point since May 2011

Kathleen De Vere

Developers may finally be seeing some relief from the summer’s high user acquisition prices reports Boston-based user acquisition and marketing company Fiksu. According to the company’s latest figures, the cost to acquire a loyal iOS user — defined as someone who will open an app at least three times — fell by 16 percent in September, hitting the lowest price seen since Apple’s offer wall crackdown.

While many had predicted the iPhone 5 launch would follow the precedent set by the 4S, which saw user acquisition costs hit $1.47, the price actually fell by 21 cents, hitting an average of $1.13 for the month.

The last time the Fiksu reported numbers this low was in May 2011, when Apple’s ban on offer walls dropped user acquisition costs to $1.10 per loyal user. User acquisition costs took a similar dive in January 2012, falling to $1.14 after the holiday advertising frenzy subsided.

According to Fisku CEO Micah Adler, app marketers did a much better job planning their iPhone 5 launch advertising campaigns than they did for the 4S, a move that allowed them to pick up new users more cheaply than anticipated.

“Brands held off on advertising in the run-up to the iPhone 5 launch, then jumped into the fray as the phones hit stores and mailboxes,” he said. “Despite the increase in advertising volume and CPCs, marketers who went after these new users were rewarded with a nice drop in overall costs for acquiring loyal users.”

On the download front, Fiksu found that the volume of free app downloads per day hit 4.07 million during September — a slight increase over August’s 4.05 million. That said, the company reported a clear delineation in download activity before and after the launch of the iPhone 5. Downloads for the month were actually down three percent before the iPhone 5 began arriving in consumer’s hands on on Sept. 21, but jumped by 33 percent after launch. One Fiksu clients reported a 20 percent increase in organic downloads and 35 percent revenue gains during the post-launch period.

Overall, Fiksu’s report seems to indicate that mobile marketers have gotten much better at planning for significant events like the launch of the iPhone 5. While download volumes and user acquisition costs are likely to rise in October, overall the costs should be lower year-over-year.（source：insidemobileapps）

2）Amazon releases first mobile game to Appstore, rival platforms

By Eric Caoili

Amazon’s in-house game studio has published its first mobile title to not just its mobile Appstore, but also to Android’s Google Play and iOS’s App Store.

Available or free (with microtransactions for additional content), Air Patriots shows of a number of features available on the Appstore (Amazon’s mobile marketplace for the Kindle Fire and Android devices), such as Whispersync cloud saves and Game Circle achievements/leaderboards.

Similar to Amazon’s strategy with its Kindle ebook reading app, which is available on both Kindle devices and the smartphones/tablets of its competitors, the company has released the Lemon Team-developed Air Patriots on rival app marketplaces.

It’s an unconventional move because game platform owners like Nintendo and Sony tend to release first-party games to their systems exclusively. With this strategy, though, Amazon can build some first-hand experience on the difficulties developers deal with when creating multiplatform mobile games, and then apply those lessons to improve its Appstore.

This is the second release from Amazon Game Studios, following the developer’s Living Classics release for Facebook in August. That title hasn’t really caught on, though, and currently has only 140,000 monthly active players. （source：gamasutra）

3）Over 100,000 Android apps pose security risk

by Daniel Gumble

Bit9 study shows 72 per cent of users use at least one high-risk permission app.

More than 100,000 Android apps pose a significant security risk to mobile users and the enterprise networks to which they connect, a Bit9 research report has shown.

The research project analysed the security permissions of over 400,000 Android applications. And with more smartphones today running Android than any other operating system, the study was based specifically on Google Play applications.

An application could be defined as suspicious according to the permissions requested by the app, its categorisation, user rating, number of downloads, and the reputation of the application’s publisher. Subsequently, Bit9 found that of the 400,000 mobiles in question, 72 per cent use at least one high-risk permission.

Furthermore, the study also shows that 42 per cent of applications access GPS location data, and these include wallpapers, games and utilities, with 31 per cent accessing phone calls or phone numbers.

It is also reported that 26 per cent access personal data, such as contacts and email, while nine per cent use permissions that can cost the user money.

Harry Sverdlove, chief technology officer for Bit9, commented on the findings: “A significant percentage of Google Play apps have access to potentially sensitive and confidential information. When a seemingly basic app such as a wallpaper requests access to GPS data, this raises a red flag. Likewise, more than a quarter of the apps can access email and contacts unbeknown to the phone user, which is of great concern when these devices are used in the workplace.”

Meanwhile, the results of a nine-month study by AdaptiveMobile recently revealed that Android battery apps are among the highest source of mobile malware in the UK.（source：mobile-ent）

4）Nexus 7 nears one million sales per month

by Daniel Gumble

Google and Asustek remain cagey on revealing actual sales figures.

Sales of Asustek’s Nexus 7 are creeping ever closer to the one million per month mark, yet the Taiwanese manufacturer remains reluctant to reveal specific sales figures.

Having caused something of a stir upon its release earlier this year due to its low starting price of $199, both Google and Asustek have been hesitant in coming forward with actual sales figures for the siven-inch tablet. However, Asustek’s executives offered the most revealing indication yet at the company’s third-quarter earning conference earlier this week.

David Chang, chief financial officer at Asustek, commented: “At the beginning, it was, for instance, 500K units a month, then maybe 600-700K. This latest month, it was close to one million.”

Earlier this month, a number of tech blogs were suggesting third-quarter sales estimates of 800,000-1 million Nexus 7s based on an analysis of Google’s revenue figures, yet Asustek’s recent comments indicate that the actual number was most likely higher.

Meanwhile, research firm Strategy Analytics revealed that 25 million tablets were sold worldwide in the third-quarter, with Apple’s iPad shifting 14 million units during that period.（source：mobile-ent）

Nokia and Rovio team up for exclusive Angry Birds Roost WinPho launch

New addition to popular mobile franchise developed for Lumia smartphone series.

Angry Birds developer Rovio has teamed up with Nokia for the WinPho launch of Angry Birds Roost, the latest addition to the mobile game franchise made exclusively for the company’s Lumia smartphone series.

In a move away from previous extensions of the game franchise, Angry Birds Roost doesn’t include a gameplay component. Instead, it has been designed as a hub for fans, offering access to premium Rovio titles, news updates, wallpapers, ringtones, user reviews and video tutorials to devices running Windows Phone 7.5 or higher.

Furthermore, Lumia owners can combine add Angry Birds characters to their own personal photos and share the results via Facebook, Twitter, MMS or email.

This joining of forces marks the latest move in Nokia’s efforts to make its Windows Phone-powered Lumia line a success, having recently teamed up with AOL to secure Entrance by AOL for the Lumia, as well as announcing the arrival of Draw Something and Words With Friends to the smartphone series.（source:mobile-ent）
