### 5/5 — 许愿语音和标签功能

*2026-08-21*

很多日记应用都有这俩功能咱们小黑鸟也要有🥹 小黑鸟做大做强吧

### 5/5 — 我喜欢信纸和胶囊样式！

*2026-08-20*

去年的心情计数显示不出来了。我只用了自定义emoji来记录事件类型，所以只用得上自定义emoji的计数，不想每次记录选感受心情，选不出来也很微妙。

### 5/5 — 非常快的更新！

*2026-08-16*

之前我反馈了一些建议，很快就更新出了这些功能

### 5/5 — 🐦‍⬛ a lovely addition to my life

*2026-05-31*

Really enjoy the apps by this developer.  Frog Count is by far my favorite, but this is also a delight.  Such a shame a lot of hidden gems get buried on this store.  I really enjoy the UI, and the price for lifetime was too good to pass up along with Frog Count.  Well wishes.  Thank you for making these. 🩶

**Developer response:** Wow, this truly means a lot to me😆
Thank you for loving both Frog Count and Bird Diary. I’m so happy that the frog🐸 and the little bird🐦‍⬛ can bring you a bit of joy.
I’ll keep creating and improving them. Thank you so much for your support!

### 4/5 — 买会员支持了，能否添加一下这个功能

*2026-05-27*

能不能加个把发了几封未来信隐藏起来的功能。现在发未来信能够看到发了几封，还能看到哪天会收到。把这些隐藏起来就感觉再收到的那天会更惊喜

### 5/5 — P人狂喜！！！

*2026-03-30*

找了很久想要那种可以以日历形式呈现的日记app，终于让我挖到宝了！ 但是不知道怎么让iPad和iPhone数据互通 但总体来说是非常好用！

**Developer response:** ipad在pro页面“恢复购买”后，多台设备上都打开icloud同步即可

### 5/5 — 这款软件真的很好！！！

*2026-03-26*

第一，它可以像真正的日记一样使用日历查找

第二，它可以搜索日记

第三，它可以写未来的信，并支持自定义

第四，它可以帮助我们快速选择日期

就说到这里，已经有许多日记软件out了

第五，可以使用表情符号来表达今天的心情，也可以使用Apple自带的表情符号

第六，它可以统计心情

说到这里，才只说了一点点功能，所以整款软件真的不错，下载一下试试看吧

### 5/5 — 给一个宝藏软件的好评

*2026-02-12*

作为一个 i 人，平时最大的宣泄口就是自己，所以发现这款软件的时候真的很惊喜，本i人真的很需要一个释放自己小小情绪的出口，这种树洞什么的不要太爱了

### 5/5 — 黑鸟日记

*2026-01-27*

一开始是用呱呱计数，觉得还挺好用的，然后看到了黑鸟日记，被里面的内容吸引，之前一直有写日记习惯 ，现在刚好用这个APP，而我还能面容解锁，感觉不容易一下就被点开，也保证了一定的私密性，还能选一些表情，有个未来信，写给未来的自己感觉还是挺不错的

### 5/5 — ❤️黑鸟日记，和时间温柔对话

*2025-12-31*

❣️❣️
对我而言，黑鸟日记更像是我的一个私密的情绪树洞。对于喜欢用文字和自己对话、偏爱仪式感的J人很合适。
✨✨
App里面的功能，让我对平淡的日常记录多了一份小期待～
🎄🎄
最让我着迷的还是是“未来信”的功能。深夜写下对某个日子的期待，设定好送达日期，就像把心事托付给了那只“偷走时间的黑鸟”，想象着未来某天突然收到这份来自当下的信，那种惊喜感光是想想就觉得很温暖。

**Developer response:** 谢谢喜欢，期待收信ヾ(◍°∇°◍)ﾉﾞ
