• 顶部选择基准音、乐器或普通模式；点击琴弦选择目标音，底部上一弦/下一弦按顺序切换，中间按钮播放或暂停。
• 默认耳机模式：耳机播放标准音和语音，iPhone 麦克风听真实乐器。普通模式可在设置开启语音引导。
• 不戴耳机：在设置开启静默调音。可选择无基准音直接检测，或先听 3、5、10 秒标准音再检测。标准音播放时不判断音准。手机输出可分别选择听筒或扬声器；连接耳机时优先使用耳机。
• 声音设置提供音色、标准音音量、语音播报音量、跟随旁白语速或手动语速、高对比度模式。
• App Store 版可主动领取 72 小时免费试用，随后选择一次买断；不订阅、不自动扣费。设置中的“购买与试用”显示剩余时间、实时商店价格、恢复购买及 Apple 优惠码入口。
• 换机/重装请使用原 App Store 账户并点恢复购买。兑换官方优惠码后若未解锁，可恢复购买。退款或撤销后权益会随 Apple 状态更新。
• 已验证的永久购买可离线使用；领取试用、购买、恢复及首次获取交易通常需要连接 Apple。试用离线仍按剩余期限计算，请保持系统日期时间正确。离线时无法实时获知退款。
• 若无法检测，检查麦克风权限、当前模式和实际音频输出，拨弦后略过起音继续听反馈。可在帮助与检测信息中查看或主动分享诊断；请附版本、机型、耳机类型、琴弦及复现步骤，不要发送密码。

Contact mkong.musician@gmail.com with the subject Access Tuner Support.

Choose a reference pitch and instrument at the top. Tap a string to select its pitch; previous/next string controls and play/pause are at the bottom. In headphone mode, reference audio and guidance use the headphones while the iPhone microphone listens to the instrument. Enable spoken guidance in settings for chromatic mode.

For use without headphones, enable silent tuning in settings. Choose no reference, or play a reference for 3, 5, or 10 seconds before detection starts. No pitch guidance occurs during the reference interval. Choose receiver or speaker independently for reference audio and guidance; connected headphones take priority.

Settings include timbre, reference and guidance volumes, speech rate, and high contrast. The App Store edition offers an explicitly claimed 72-hour free trial and a one-time permanent unlock, with no subscription or automatic charge. Purchase & Trial includes remaining time, current App Store pricing, restoration, and official Apple offer redemption.

Restore using your original App Store account after reinstalling or changing devices. Restore again if an offer redemption has not appeared. Verified permanent access can work offline; claiming, purchasing, restoring, and first retrieving transactions generally require Apple connectivity. Offline trials still expire, and refunds cannot be detected until Apple updates reach the device. Keep system time correct.

For audio issues, check microphone permission, mode, and the actual route. Include version, iPhone model, headphone type, instrument/string, and reproduction steps in a support email. Share diagnostic text only if you choose; do not send passwords.
