Duofold
轻轻合上。Close, softly.
合上 MacBook 的那一刻，画面停在空中，
随之后倾、失焦、渐暗。
As the lid comes down, the picture holds still in space,
then leans back, softens and fades.

功能Features
跟手，不止好看。Right with your hand.
读取屏幕开合角度，每一帧都按你合上的速度实时绘制。 It reads the lid angle and draws every frame at the speed you close it.
画面停在空中Holds still in space
屏幕合拢，画面却像留在原处。透视、景深模糊与渐暗，都由 GPU 实时完成。The glass folds while the picture stays put, with perspective, depth blur and dimming drawn live on the GPU.
跟得上你的手Keeps up with you
按合屏的速度预测下一刻的角度，快合慢合都顺滑，画面从真实屏幕连续地弯下去。It predicts where the lid is heading, so fast or slow, the picture bends smoothly away from the real screen.
三种风格，随心调Three looks, or your own
柔和、经典、强烈一键切换；也能逐项调整起始角度、模糊、渐暗与透视。Subtle, Classic or Dramatic in a click, or set the start angle, blur, dimming and perspective yourself.
一动鼠标就让开Steps aside for you
合到一半想接着用？动一下鼠标或按个键，效果立即退开，画面还给你。Want the Mac back with the lid half down? Touch the mouse or a key and the effect steps aside.
画面不离开你的 MacPrivate by design
屏幕画面只在本机实时处理，不录制、不保存、不上传。The picture is processed live on your Mac. Nothing is recorded, kept or uploaded.
安静待命Quiet in the background
关掉窗口也在后台运行，只在合屏时工作，平时几乎不占资源；新版本自动提醒。It keeps running after you close its window, works only while the lid moves, and tells you when there's an update.

常见问题FAQ
你可能想知道。Good questions.
我的 MacBook 能用吗？Will it work on my MacBook?
需要带屏幕开合角度传感器的 MacBook，近几年的 MacBook Air 和 MacBook Pro 大多具备。打开 App 会自动检测，建议在试用期内确认可用再购买。It needs a MacBook with a lid angle sensor, which most recent MacBook Air and MacBook Pro models have. The app checks when it opens, so you can make sure during the trial before you buy.
为什么需要屏幕录制权限？Why does it need Screen Recording?
效果要拿到当前的屏幕画面才能让它倾斜、模糊。画面只在本机的 GPU 上实时处理，不录制、不保存、不上传。To lean and blur what's on screen, it has to see it. The picture is processed live on your Mac's GPU and is never recorded, kept or uploaded.
会耗电或拖慢电脑吗？Will it drain the battery or slow things down?
只在屏幕合拢的那几秒工作，其余时间只是偶尔读一下角度，几乎不占资源。It only works for the few seconds the lid is moving. The rest of the time it just checks the angle now and then.
锁屏的时候有效果吗？Does it show on the lock screen?
不会。锁屏界面受 macOS 保护，任何 App 都不能在上面显示内容，解锁后即恢复。No. macOS protects the lock screen so no app can draw over it. The effect is back as soon as you unlock.
换了电脑还能用吗？What if I get a new Mac?
购买记录跟着账户走。在新 Mac 上登录同一账户，就能继续使用。Your purchase belongs to your account. Sign in on the new Mac and it's there.
合上，看看。Close it and see.
