## What is Knock Knock?

Be neighbors with your friends, and knock when you miss them.

Knock Knock is a small app for sharing everyday life with your closest friends. Invite friends to be your neighbors, and drop by their door anytime, no matter how far apart you are.

Miss them? Knock knock
Knock on a friend's door in your own rhythm to let them know you're thinking of them right now.

Open the door and share the moment
When someone knocks, answer with the view in front of you, a peephole selfie, or your latest photo.

Apart, but in the same photo
Got a photo or video from a friend? Take a photo together with it!

Pin your days to your door
Pick a few recent photos to decorate your door. When friends drop by, they'll see what you've been up to.

Keep your friends' doors on your Home Screen
Add the widget to put your friends' doors and door photos on your Home Screen. Tap it to go straight to their door.

### 5/5 — 简洁无负担很可爱

*2026-10-23*

现在的功能很可爱很喜欢，就是tag默认，只能选择，不能自己打字，互动很有限，建议增加tag可修改功能。
有时候看到对方照片或者照片回复想再聊两句，但没有途径发，可以加喊话功能吗？可以选择以小喇叭语音播放，或者用气泡对话框出现在他门上，或者作为信件来回写信。
喜欢敲门没反应还能给对方搞破坏的功能，就是对方好像看不到，可以让对面看到然后清理。
看到有陌生的门，应该是新增的社交功能，但是敲门没有反应，可以定期刷新吗？或者把愿意接受陌生人的用户放到一个池子里，这样喜欢安静的也不会被打扰。另外如果是陌生人，可以做权限管理，先不对他展示家里面的照片吗？隐私还是很重要的

### 5/5 — 不会玩

*2026-10-19*

挺有意思的，但我玩不明白

### 5/5 — 说明书！

*2026-10-19*

很有意思呀，但是有点玩不明白，需要说明书...

### 5/5 — 哈喽👋

*2026-10-09*

哈喽👋亲爱的工程师邻居，能否再提供两个功能，一是允许上传自己制作的房门照片；一是能在照片上自主留言，但每天只有一次机会。by the way 请快快上安卓版本吧，please!
