最后更新：2026 年 6 月 24 日
主界面提供四种方式：转动大转盘、点击 − / + 步进、打开数字键盘直接输入、或用 Tap 按节奏连续点击自动测速。
请确认：① 手机侧边的静音/响铃开关处于响铃档；② 系统媒体音量已调高；③ 首次进入后台时如系统询问，请允许 App 继续播放。节拍器在后台与锁屏状态下可持续发声。
调音器需要麦克风权限。请在 系统设置 → 隐私与安全性 → 麦克风 中允许“节拍器”。音频只在本机实时处理用于检测音高，不会录制或上传。请在安静环境下、让乐器靠近麦克风以获得更稳定的读数。
进入“音色”页可切换多种节拍音色，并开启中文或英文的语音报拍。
不会。所有设置与预设都保存在你的设备本地，不依赖任何账号或服务器。卸载 App 才会删除这些数据。

A professional, reliable, forever-free metronome
Last updated: June 24, 2026
The main screen offers four ways: turn the large dial, tap − / + to step, open the number pad to type a value, or use Tap to set the tempo by tapping along.
Please check: (1) the side ring/silent switch is set to ring; (2) the system media volume is turned up; (3) allow the app to keep playing if the system asks the first time you background it. The metronome keeps sounding in the background and on the lock screen.
The tuner needs microphone permission. Allow "节拍器" in Settings → Privacy & Security → Microphone. Audio is processed on-device in real time to detect pitch and is never recorded or uploaded. Use it in a quiet place with your instrument close to the mic for stable readings.
Open the "Sounds" page to switch between multiple click sounds and enable voice counting in Chinese or English.
No. All settings and presets are stored locally on your device, with no account or server required. They are removed only if you uninstall the app.
Forever free. No ads, no in-app purchases, no subscriptions, and no account required — every feature is open to use.
iPhone running iOS 13.0 or later.
