听力测试声音太大

这个听力测试一上来声音开这么大差点把我震聋了,气死

Response from developer

您好,非常感谢您的评价。音量级别应当可以从高到低进行调节。考虑到每个人的听力情况不同,覆盖所有用户非常重要。我会研究如何通过更友好的用户界面来解决您提出的问题。再次感谢您,祝您有美好的一天。

感受

初次运行立体声,音调,会卡着动不了。试用,这个功能这么简单,和收费价格严重不配

Response from developer

你好,非常感谢你的评价。我在我的几台设备上没有复现你的问题,但我会继续调查。目前我没有从那边收到其他反馈,所以这可能是一次性的情况。方便的时候能否请你再试一次?我的套餐包含所有付费功能,你将能够使用所有这些功能。所以价格并不仅仅是针对这一项功能。我认为这是合理的,但我也会进行比较。再次感谢你,祝你有美好的一天。

上来就要钱啊?

还没试用,直接收费,很久没遇到这样的app了

Response from developer

你好,非常感谢你的评价。你可以免费尝试每个功能,但会有一些限制。有些功能(例如分贝计)会每天补充。我不想强迫用户付费。再次感谢,祝你有美好的一天。

糟糕的本地化翻译出来

这款软件本地化翻译做的很不好,在立体声测试环节中,竟然把“右侧”翻译为“正确的”,即便这两个意思是同一个单词。

Response from developer

您好,非常感谢您的反馈。我已经更新了部分语言的本地化内容,并将尽快完成所有语言的更新。我相信这将带来改进。再次感谢您,祝您一天愉快。

给我测1000赫兹声音,这不是扯

Response from developer

您好,非常感谢您的评论。我们无法理解您的问题。能否请您提供更多信息?我们相信我们会尽快解决您的问题。再次感谢您,祝您愉快。
