你有一百万个下载一款应用的原因，例如同伴压力、好奇心等等。但要知道用户会何时抛弃一款应用，却真是个难题。根据uTest针对成百上千个品牌的手机应用测试结果，我们总结了人们卸载手机应用的五个原因：

1.应用崩溃或毫无反应：没有什么比手机应用不时崩溃，中止或毫无反应更让人抓狂了。运行缓慢是用户抛弃一款应用的头号原因。最近调查发现，79%用户表示自己会再次或两次尝试首次运行失败的应用。但仅有16%受访者称自己会尝试两次以上。Applause（游戏邦注：这是一款手机应用分析工具）数据显示，在用户评论中出现“崩溃”字眼的应用，比一般应用更易于仅获得1或2颗星评价。优秀的开发者会先测试自己的手机应用，找到根源，然后发布漏洞补丁。所以如果你喜欢某款应用，并愿意等待修复版本问世，那你可以再等一等。但如果这个问题持续得不到解决，开发者似乎对此漠不关心，那你可能就会删除它。

2.应用的用法不直观：应用应该让我们的生活更轻松更有趣。如果一款应用无法实现任何一个目的——假如它让我们的生活更麻烦，那我们很可能就会另寻出路。要相信用设计更像是一门科学而非艺术，这其中会涉及标准化的布局，设计和功能。有些应用在竖屏模式下可能会出现分辨率问题，有些可能在复杂的导航中隐藏了关键信息，有些图标和按钮太小，或者排列过于紧凑，总之手机应用具有多种多样的易用性问题。虽然其中一个瑕疵不足以酿成大错，但如果多个问题结合在一起，就很可能导致用户卸载应用了。

3.应用（在未经用户许可的情况下）搜集个人信息：开发者通常都有向用户要求获得许可的自由，一般会要求获得比应用实际需求更多的权限。在2012年早期，很多人都知道了应用访问通讯录和其他数据及功能时可能会泄露用户个人隐私的真相。这一情况被媒体曝光之后引起了舆论的极大反弹，导致许多操作系统开始关注用户授权这一层面的问题。虽然从技术上讲，应用能够搜集大量数据（游戏邦注：包括日历、通讯录、地理位置），或者要求用户注册使用自己的社交认证信息，但这一举措常会招致用户反感。

4.用户更喜欢移动网页版本：这是极少见的情况，但有时候用户就是更喜欢一个产品或服务的移动网页版本而非原生应用版本。我们在uTest仍然将移动网页视为原生应用的“附属产品”，而非“取代性”产品。随着HTML5技术的成熟，以及响应式设计的出现，4G的加速发展，我们将来有望看到更多用户选择移动网页，虽然我们目前还是认为原生应用才是王道。

5.应用并未针对设备进行优化：开发者针对平板电脑移植现成的智能手机应用已经成为一种普遍现象。但这种做法却限制了用户体验。正如易用性专家Jackob Nielsen所言，“比起手机设备短暂快速的点击体验，平板电脑的大屏幕更关注长期的沉浸式用户体验。”换句话说，如果你发布一款“兼容于所有设备”的应用，那就不要怪用户在其中一个或所有设备上将其卸载了。（本文为游戏邦/gamerboom.com编译，拒绝任何不保留版权的转载，如需转载请联系：游戏邦）

Five reasons users uninstall mobile apps

This sponsored post is produced by uTest.

You have a million different reasons to download an app. Peer pressure. Curiosity. The list goes on. But knowing when to let go of a mobile app, well, that’s the tricky part. We want to make that decision a little easier, so based upon uTest’s observations testing mobile apps for hundreds of top brands, here are five of the top reasons to uninstall a mobile app.

1.The app crashes or freezes: Few things are as frustrating as a mobile app that continually crashes, hangs, or freezes. Slow performance (or sometimes, no performance) is the number one reason why users abandon a mobile app. A recent study found that 79 percent of users said they would retry an app once or twice if it failed to work the first time. Only 16 percent said they would give it more than two attempts. Data from Applause (a mobile app analytics tool) shows that reviews with the word “crash” are eight times more likely to be 1 or 2 stars than the average review. The good developers will test their mobile apps, identify the root cause, and make it a top priority to release a bug-fix. So if you like the idea of the app and are willing to wait for a fix, you should do so. But if the problem persists and no one seems to be doing anything about it, it might be time to get rid of it.

2.The app isn’t intuitive to use: Apps should make our lives easier and more enjoyable. If an app accomplishes neither – if it makes life more difficult – users will likely go elsewhere. Believe it or not, app design is really more of a science than an art; there are proven standards for layout, design and functionality. Maybe the app does a poor job of adapting to portrait resolution; maybe key information is hidden in a complex navigation; maybe icons and buttons are too small or grouped too closely together. There are a number of usability problems that plague mobile apps. While one hang-up might not push one over the edge, when combined, they often result in users uninstalling the app.

3.The app is collecting your personal info (without your consent): Developers have historically been liberal in asking for permissions, typically requesting more access than is strictly necessary for the app to function properly. In early 2012 it came to light that apps were accessing address books and other data and features without any good reason. This practice was exposed by the media to much public backlash, resulting in many operating systems keeping a closer eye on permissions. While it might be technically legal for an app to collect excessive data (calendar, address book, location) or require one to sign-up using their social credentials, the practice has come to be frowned upon by users.

4.Users prefer the mobile web version: It’s increasingly rare – the numbers don’t lie – but sometimes users simply prefer the mobile web version of a product or service to that of the native app. At uTest, we’re still seeing the mobile web as “in addition to” native apps, not “instead of” the native versions. As HTML 5 matures, along with the advent of responsive design and 4G speeds, we expect to see more users opting for the mobile web, even though we firmly believe that apps are here to stay.

5.The app is not optimized for the device: It’s rather common in the mobile world for developers to “port” their existing smartphone apps to the tablet. In doing so, they severely limit the user experience. As usability guru Jackob Nielsen once pointed out, “The bigger screen of the tablet allows one to include features, and more focus on immersive use over longer periods of time than the quick hits that are most useful on phone-sized devices.” In other words, if you launch a “one size fits all app”, don’t be surprised when users uninstall it on one (or all) of their devices.（source：venturebeat）
