许大师 vs 格物 Whence

许大师是一款面向 iPhone 的设备状态监测与硬件分析工具。把「看清设备状态」和「读懂硬件配置」放在一起：支持导入系统诊断文件，在本机完成硬件信息解析；同时提供实时状态监测、灵动岛/小组件展示，以及一系列实用检测工具。 【硬件分析 · 核心能力】 • 导入系统诊断归档 / 相关日志，生成本机硬件分析报告 • 解析设备硬件相关配置信息，辅助了解机型与部件概况 • 诊断文件仅在本机解析，不上传完整诊断包 • 序列号等敏感信息默认脱敏显示，兼顾可读与隐私 【设备状态 · 一目了然】 • 电量、内存、网络速率等关键状态实时展示 • 热状态等指标在系统可访问范围内辅助估算（仅供参考） • 支持刷新间隔设置，按需平衡实时性与耗电 【灵动岛 · 小组件 · 实时活动】 • 关键动岛 / 实时活动快速查看关注指标 • 桌面与锁屏小组件同步设备与网络状态 【实用工具箱】 • 网络：Ping 延迟、抖动与失败率参考 • 存储：顺序 / 随机读写等性能测试 • 屏幕：色彩、坏点、亮度一致性检查 • 触控：多点触控检测 • 其他：二维码扫描与生成、密码生成、指南针、分贝仪等 【隐私与本地优先】 • 尽量在本机处理设备状态与诊断数据 • 不主动收集个人隐私信息，不进行广告追踪 • 定位权限仅用于按系统要求读取 Wi‑Fi 名称，不获取或上传位置坐标 • 相机、麦克风等权限仅在对应功能使用时按需申请 【使用说明】 部分数据受 iOS 系统限制，可能为可访问范围内的估算值或占位说明，仅供参考，不作为维修、保修或

Whence lays open where the devices around you actually come from — what you are connected to, and what you are holding. ■ Looking outward: what your Wi-Fi actually is • Reads the BSSID of the access point you're on and resolves the manufacturer from the IEEE registry • When the BSSID is a locally administered address, it says so — such addresses do not identify a real manufacturer. The three possible causes are shown side by side rather than picking one for you. ■ Looking inward: what this iPhone is made of • Core split, native resolution and refresh rate, per-lens camera parameters, sensors and radios, storage and power — all measured directly • Model specifications from a bundled catalog, cross-checked against what was measured, with the result shown either way ■ Every value is labeled with where it came from Measured, catalog, inferred, unavailable — four distinct provenance levels. Anything inferred is visually de-emphasized and carries an explanation. You can see at a glance what was actually read. ■ We say plainly what cannot be read Battery health, cycle count, and the real suppliers of the display and battery are not available to third-party apps on iOS. This app tells you it cannot read them, rather than leaving a blank or filling in an estimate. Any app claiming to detect these directly on an iPhone is not telling you the truth. ■ Privacy • Makes no network requests at all — not merely no external ones. All manufacturer and model data ships inside the app. • Collects nothing, uploads nothing. • Declares exactly one permission: location. It is used solely to satisfy iOS's precondition for reading Wi-Fi information — no coordinates are requested, stored, or transmitted.
