失眠之后找到的很好的软件!

最近失眠,然后想要听一些下雨声音,白噪音这些,这个软件就很好用。感觉给我下来了好几晚的好的睡眠,感谢作者!关键大部分功能都是免费的!太感谢了!

Response from developer

感谢您的走心评价!做《开睡》的初衷,就是希望能帮到被失眠困扰的朋友。下雨声和白噪音确实是大自然最好的“催眠曲”,听到它能让您睡个好觉,我真的比什么都高兴!把大部分核心功能做成免费,也是希望能实实在在地陪伴大家。祝您以后夜夜好梦,如果有特别想听的新声音,随时留言告诉我哦!💤

睡眠变好了

最近压力有点大、有些时候还是想要听着白噪音或者雨声才能睡着,真不容易,作者基本功能已经够我用了!感谢作者这么大方!yyds

Response from developer

感谢您的“yyds”最高评价!最近生活/工作压力大辛苦啦,《开睡》就是希望能在这些疲惫的夜晚,为您提供一个可以彻底放松的“数字避风港”。您觉得基础功能够用就好,我会一直保留这些免费的白噪音和雨声陪伴大家。今晚也请彻底放下压力,听着雨声好好睡一觉吧,祝您每天都能满血复活,好梦!💤

不错

用了几天,对于入睡困难者听点白噪音帮助入睡还是挺好的

Response from developer

谢谢彬彬嘉华的五星好评!“入睡困难”确实太折磨人了,越想睡越睡不着。很高兴开睡的白噪音能帮你放松下来、顺利入睡。这也是我做这款 App 最想看到的事情——在每一个你失眠、焦虑的深夜,用声音给你搭一个安安静静的避风港。感谢你的肯定,祝你以后天天都有好睡眠,越睡越香!

意外的挺好用,确实能催眠

平时很少写评价,但这软件确实有点东西。以前晚上经常躺着刷手机到一两点,越刷越精神。现在强迫自己放下手机,打开开睡放那几首喜欢的音乐。可能是有什么神奇磁场吧,听着听着不知不觉就睡着了,这几天睡眠质量明显上去了。起来还能看一眼睡眠记录,挺有意思的。良心工具,大赞!

Response from developer

哈哈,被你发现了!其实这“神奇磁场”背后没啥魔法,全是我在挑歌时死磕的“催眠代码”在起作用。😂 非常感谢小灰灰特意跑来写下这段长评,对于平时不爱写评价的你来说,这绝对是最高荣誉了。刷手机确实是睡眠头号杀手,你能强迫自己放下手机并被开睡成功“催眠”,这自律和效果都必须给满分!祝你以后天天沾床就睡,睡眠记录里全是一觉到天亮的好数据!

助眠神器-开睡

每次失眠的时候,打开开睡总能让我瞬间静心,进入入睡状态,歌单里有几首音乐很喜欢,感谢开睡让我有了的质量的睡眠,还能记录睡眠记,就很不错。

Response from developer

哇,谢谢“一条小河”这么暖心的长评!看到“瞬间静心”这四个字,我真的觉得做这款 App 的所有意义都达到了。现代人压力大,失眠真的太折磨人了,开睡能用歌单里的音乐帮到你,是它最大的荣幸。能帮你的睡眠质量“立大功”,开睡这个小工具的任务就完成了。现在大家白天压力大,晚上脑子太难停下来了,“瞬间静心”真的是非常高的评价。听到你能喜欢里面的音乐和睡眠日记,真的给了我极大的优化动力。希望在每一个你需要安静的深夜,开睡都能成为最懂你的那个树洞。祝你天天都有好梦,晚安!
