Please review before using the App:
课程封面与在线视频需要网络；部分姿态演示与本地偏好可在弱网或离线环境下浏览。为保证最佳体验，建议在稳定网络下使用。
请先在「相机与姿态追踪校准」中完成校准；保持光线充足、全身入镜，并避免杂乱背景。可在设置中切换前置/后置相机与镜像模式。
相机仅用于 AI 动作捕捉与实时姿态纠错练习。您可在 iOS「设置 → 隐私与安全性 → 相机」中随时关闭；关闭后相关功能将不可用。
每天在「日程」中完成打卡即可累计。若需重置当日打卡状态，可在「账号与偏好」中操作。
请检查网络连接与系统音量，稍后重试。若仍失败，请将设备型号、系统版本、应用版本与问题截图发送至 support@choreoai.app。
可在应用内「帮助与 AI 导师反馈」提交，或直接发送邮件至 support@choreoai.app，请尽量描述复现步骤。
Course covers and online videos need network access. Some pose demos and local preferences can work offline or on a weak network. For the best experience, use a stable connection.
Complete Camera & Pose Calibration first. Keep good lighting, stay fully in frame, and avoid cluttered backgrounds. You can switch front/rear camera and mirror mode in settings.
The camera is used only for AI motion capture and real-time posture correction. You can revoke access in iOS Settings → Privacy & Security → Camera; related features will then be unavailable.
Complete a check-in on the Schedule tab once per day. You can reset today’s check-in from Account & Preferences if needed.
Check your network and system volume, then try again. If it still fails, email support@choreoai.app with device model, iOS version, app version, and screenshots.
