Finger Filter

Support

Finger Filter tracks your hand in real time and places a live filter in the gaps between your fingers. If something isn't working as expected, check the topics below first — most issues have a quick fix.

The filter isn't showing up between my fingers

Make sure your whole hand, including all fingertips, is inside the frame and well lit. Spread your fingers apart so there's a visible gap between them — the filter is drawn into that gap, so if your fingers are touching there's nothing to draw it into. Hold your hand steady for a moment; tracking can take a beat to lock on after you first raise your hand or after fast motion.

The camera screen is black, or the app asks for camera access

Finger Filter needs camera access to work at all. If you tapped "Don't Allow" when first asked, open Settings → Finger Filter on your device and turn Camera access on, then relaunch the app.

My recording has no sound

Check that the in-app microphone toggle is turned on before you start recording — it's off by default so you can choose per recording. If it's on and there's still no sound, open Settings → Finger Filter and confirm Microphone access is allowed.

I can't save my recording to Photos

Saving requires permission to add items to your Photo Library. Open Settings → Finger Filter → Photos and make sure it's set to "Add Photos Only" or "All Photos", not "None".

The picture looks cropped, small, or off-center

On iPad, the front camera's field of view depends on the model and orientation. Try rotating the device or moving a little farther from the camera. If this still looks wrong on your specific device, please write in — include the device model and iPadOS/iOS version so it can be checked against that hardware.

The app is running slowly or gets warm

Real-time hand tracking and live video filters are demanding on the device's camera and graphics hardware. This is expected during long recording sessions, especially in bright light or at high resolution. If it happens within the first few seconds of opening the app, please get in touch — that's not expected.

Still stuck?

Send an email with a short description of what happened, your device model, and your iOS version. A screen recording, if you can grab one, usually helps more than a written description.

Privacy

Finger Filter has no servers, no analytics, and no ads — everything runs on your device. See the Privacy Policy for details.

技术支持

「手指滤镜」通过实时追踪你的手部,把滤镜画面叠加在手指之间的缝隙里。如果遇到问题, 可以先看看下面这些常见情况——大多数问题都能很快解决。

指缝之间没有出现滤镜

请确保整只手(包括所有指尖)都在镜头画面内,并且光线充足。把手指分开一点, 留出明显的缝隙——滤镜是画在指缝里的,手指并拢的话就没有地方可以画。刚举起手 或者手部快速移动之后,追踪需要一点时间才能锁定,保持手部稍微静止一下即可。

摄像头画面是黑的,或者一直提示需要摄像头权限

「手指滤镜」必须获得摄像头权限才能工作。如果第一次弹出权限提示时点了"不允许", 请到系统「设置」→「手指滤镜」里把摄像头权限打开,然后重新打开 App。

录制的视频没有声音

请检查录制前 App 内的麦克风开关是否已打开——默认是关闭的,方便你每次录制前自己 决定要不要收音。如果已经打开却还是没有声音,请到「设置」→「手指滤镜」 确认麦克风权限是否被允许。

无法把录制内容保存到相册

保存到相册需要"添加照片"权限。请到「设置」→「手指滤镜」→「照片」, 确保设置为"仅添加照片"或"所有照片",而不是"无"。

画面看起来被裁切、偏小或者位置不居中

在 iPad 上,前置摄像头的视野范围会因机型和横竖屏方向而不同。可以尝试旋转设备, 或者稍微离摄像头远一点。如果在你的具体机型上这个问题始终存在,欢迎写信告诉我们 设备型号和系统版本,方便针对该机型排查。

App 运行变慢或者设备发热

实时手部追踪和实时滤镜渲染对摄像头和图形硬件的负载较大,长时间录制、强光环境或 高分辨率下出现这种情况是正常现象。但如果打开 App 几秒钟内就出现这种情况,请与 我们联系,这不是预期表现。

问题还没解决?

请发邮件简单描述遇到的情况、你的设备型号和系统版本。如果方便的话,附上一段屏幕 录屏,通常比文字描述更容易帮我们定位问题。
