一、遇到问题先看这里 Try these first
- 录音没有转写或没有评分：确认系统「设置 → 隐私与安全性」里已允许本 App 使用麦克风与语音识别；环境太安静或回答只有两三句时，转写和评分都会不稳定。
If a recording produces no transcript or no score: allow Microphone and Speech Recognition for the app in iOS Settings › Privacy & Security. Very quiet audio or two-sentence answers also make results unstable. - 已付款但会员没解锁：在「我的 → 订阅管理」点「恢复购买」。仍然没恢复的话，请把 App Store 收据邮件发给我们。
Paid but membership is not active: use Restore Purchase under Profile › Subscription Management. If it still does not restore, send us the App Store receipt. - 纠音页某句没有标出单词：单句回答或几乎没有可发音内容时，逐句纠音会只剩评分维度；多录几句就会有标音提示。
The sentence-level coaching needs a few sentences of speech to highlight words to practice. - 分数看起来偏高或偏低：回答越完整、越贴合题目，三项（发音 / 流利度 / 内容）评分越稳定。发音分另有本地音素测量参与，不会被模型随意改写。
Scores are more stable with fuller, on-topic answers. The pronunciation dimension is anchored to measured audio.
二、订阅与退款 Subscriptions & refunds
订阅由 Apple App Store 处理，取消、换套餐、申请退款都请在 Apple 侧操作：reportaproblem.apple.com，或「设置 → 顶部头像 → 订阅」。试用结束时由 Apple 负责扣费，我们不会接触你的支付信息。
All purchases, changes and refunds are handled by Apple: reportaproblem.apple.com, or Settings › your name › Subscriptions. We never see your payment information.
