安装与打开

NF节拍器仅在 Apple Watch 上运行，没有独立的 iPhone 操作界面。安装完成后，请在手表上打开。测试版通过与手表配对的 iPhone 上的 TestFlight 安装，正式版按 App Store 的安装提示操作。

设备与最低系统要求以 App Store 或 TestFlight 页面显示为准。不同机型和系统的音频输出、触觉感受及待机播放表现可能不同。

开始使用

开始与停止：在主界面点击“开始”，播放时点击“停止”。VU 表界面可通过播放按钮开始或停止。停止后再次开始，会从小节第一拍重新播放。
调整速度：通过数码表冠或加减按钮调整 BPM，范围为 30–300 BPM。播放中也可以调整速度。
敲击定速：跟着节奏连续敲击“测速”按钮四次，App 会据此设置 BPM。英文界面的按钮显示为 TAP。
拍号与首拍重音：在设置页选择 2/4、3/4、4/4 或 6/8，并按需要开启“首拍加重”。6/8 按每小节六个均匀脉冲播放；首拍重音适用于 200 BPM 及以下。
切换界面与语言：左右滑动切换数字闪灯界面、VU 表界面与设置页。在设置页选择中文或英文，BPM、拍号、语言等偏好会保存在设备本地。
音量与蓝牙播放：在设置页的“音量调节”中点击“点击激活”，再旋转表冠调节系统音量。蓝牙耳机或音箱需要与 Apple Watch 配对，确认声音输出到连接设备后，再开始播放。

待机与返回应用

屏幕进入待机后，App 画面会变黑，这是预期的显示方式。抬腕或轻点屏幕可恢复原页面。按表冠离开 App，或发生系统音频中断时，播放会停止，需要返回后手动重新开始。

常见问题

声音无法启动或意外停止
先记录完整提示，确认手表不在充电、音量合适且声音输出设备可用；使用蓝牙设备时，检查连接状态，再点击“开始”重试。如果仍无法播放，可退出并重新打开 App。反复出现时，请按下方方式反馈。

振动时出现额外系统提示音
为避免振动附带系统提示音，建议在手表设置-声效与触感反馈中开启静音模式。App 的开屏说明可选择“不再提醒”；这一选项只关闭提醒，不会代替你修改系统静音设置。

高速度下没有首拍重音
超过 200 BPM 时，当前版本全部使用轻拍。降回 200 BPM 或以下后，若此前开启了“首拍加重”，重音会恢复。这是当前播放策略。

蓝牙声音与手腕振动有延迟差异
蓝牙设备可能带来额外播放延迟，实际表现取决于连接设备与系统。请分别观察声音、振动和画面；反馈时说明使用的是手表扬声器、蓝牙耳机还是蓝牙音箱。

费用与账号

NF节拍器永久免费，无需注册，无广告，无订阅或 App 内购买。

NF Metronome Support

NF ACOUS

NF Metronome is a standalone Apple Watch app for music practice, with audible beats, wrist haptics and two visual modes. This page covers basic use, common questions and how to send feedback.

Install and open the app

NF Metronome runs only on Apple Watch and has no separate iPhone interface. Open it on your watch after installation. Install the beta through TestFlight on your paired iPhone. For the released app, follow the App Store installation instructions.

Check the App Store or TestFlight listing for device and minimum system requirements. Audio output, haptic feel and wrist-down playback behavior can vary by watch model and system version.

Get started

Start and stop: Tap START on the main screen to play and STOP to stop. Use the playback button in VU mode for the same controls. Starting again after stopping begins at the first beat of the bar.
Adjust the tempo: Use the Digital Crown or the plus and minus buttons to set 30–300 BPM. You can change the tempo during playback.
Set a tempo by tapping: Tap the tempo button four times in rhythm to set the BPM. The English interface labels this button TAP.
Choose a time signature and accent: In Settings, choose 2/4, 3/4, 4/4 or 6/8 and enable ACCENT FIRST BEAT if needed. The 6/8 setting produces six evenly spaced pulses per bar. First-beat accents are available at 200 BPM or below.
Switch the display and language: Swipe left or right between the flashing beat display, VU meter and Settings. Choose Chinese or English in Settings. Preferences such as tempo, time signature and language are saved locally.
Adjust volume and use Bluetooth audio: Under VOLUME in Settings, tap Activate, then turn the Digital Crown to adjust system volume. Pair compatible Bluetooth headphones or a speaker with Apple Watch and confirm the audio output before starting playback.

Dimmed display and returning to the app

The app shows a black screen when the display enters its dimmed state. This is expected. Raise your wrist or tap the screen to return to the current page. Leaving the app with the Digital Crown or a system audio interruption stops playback. Return to the app and start again manually.

Common questions

Audio cannot start or stops unexpectedly
Note the full message. Check that your watch is off its charger, the volume is suitable and an audio output is available. Check any Bluetooth connection, then tap START to retry. If needed, close and reopen the app. Report recurring problems using the details below.

Extra system sounds during haptic feedback
To avoid system sounds accompanying haptics, enable Silent Mode in your watch’s Sounds & Haptics settings. You can select Don’t remind me in the app’s startup notice. This dismisses future reminders; it does not change the system Silent Mode setting.

No accent on the first beat at a high tempo
Above 200 BPM, the current version uses light beats throughout. Reduce the tempo to 200 BPM or below to restore the accent if ACCENT FIRST BEAT was enabled. This is the current playback policy.

Bluetooth audio and haptics feel out of sync
Bluetooth devices can add audio delay. Results depend on the connected device and system. Check audio, haptics and visuals separately, and tell us whether you used the watch speaker, Bluetooth headphones or a Bluetooth speaker.

Pricing and accounts

NF Metronome is free forever. No sign-up, ads, subscriptions or in-app purchases.
