博策云枢 vs Presqen

帮你把零散想法整理成清晰结构，适合学习梳理、项目拆解和会议记录。 【随手记下，结构一目了然】 
从中心主题向外延展，添加子节点或同级节点，拖到合适位置，用颜色区分层级。双指缩放画布，也能用右上角按钮放大缩小，大图一样好操作。 【模板开局，少走空白页】 * 学习笔记：核心概念、重点难点、实践应用 * 项目规划：目标、里程碑、风险与资源 * 会议记录：议题、决议、后续行动 * 空白导图：从零开始自由创作 【大纲与画布，两种视角】 
需要看全局时用画布；需要逐条核对时切到大纲，编辑、增删都在同一份导图上完成。 【导出与备份】 
导图可导出为 PNG，在分享菜单中发送，或保存到照片库（含屏幕外节点）。设置里支持导出、导入 JSON，换机或备份都能把数据带走。导入时可选择作为新导图，或覆盖相同导图。

This app helps you track attendance at events. Simply take a photo or select one from your album, and the app will intelligently and automatically identify the people in the image and provide a headcount. You can verify and adjust the count, enter the expected number of attendees, and view the actual attendance, number of absentees, and attendance rate. It is ideal for scenarios requiring on-the-spot headcounts, such as regular meetings, training sessions, seminars, performances, and lectures. Key Features · Take photos or select images from your album (supports JPG, PNG, and HEIC formats) · Intelligent, on-device automatic headcount detection; manually add/remove individuals or enter the count directly · Input the expected number of attendees to automatically calculate the attendance rate and number of absentees · Save event details, including name, time, notes, and the event photo · View history by "All," "This Week," or "This Month"; edit or delete records as needed · View attendance rate trends and compare expected versus actual attendance · Adjust settings for detection accuracy, image compression, and detection box display
