A-tube 帮帮是一款为长辈和家人设计的简洁协助入口。 遇到手机使用问题时,长辈可以先选择预先设置的可信家人,再由系统打开 FaceTime。通话开始后,可按 FaceTime 的系统提示共享屏幕;只有长辈亲自确认后,家人才可能进行协助操作。 主要特点: • 大字、大按钮、步骤清楚 • 最多设置 4 位可信家人 • 一键打开 FaceTime 视频通话 • 清楚提示屏幕共享和控制需要本人确认 • 联系人资料、头像和家属设置码只保存在本机 • 不含广告、订阅、分析或用户跟踪 • 不录制、不上传通话或屏幕内容 安全提醒:请只向熟悉且可信的家人共享屏幕。不要向陌生人、客服、银行或自称公检法的人员共享屏幕。 本 App 不自行提供远程控制服务。视频通话、屏幕共享和远程控制能力由 Apple FaceTime 与系统功能提供,并受设备、系统版本、地区和 Apple 服务可用性影响。
