Device Lab vs 格物 Whence

Device Lab 是一款围绕设备与芯片信息构建的本地化资料与工具 App，包含硬件状态监控、参数整理、芯片与设备对比、系统信息查看与实用工具，帮助你更系统、更直观地理解和管理你所使用的设备。 核心板块 • 概览：集中展示当前设备的关键信息与运行状态，如发热状态、CPU占用、内存占用、当前网速信息等，重要数据一目了然，支持通过桌面小组件或画中画查看，让监控信息随时可见。 • 芯片：系统化整理各代芯片的核心规格与技术参数，支持同系列、跨代际对比，直观呈现架构差异与升级重点。 • 设备：收录不同设备的硬件配置与技术参数，清晰展示不同型号之间的差异，方便在选购、对比或查阅时快速获得可靠信息。 • 工具：汇总与设备和芯片相关的性能参考与测试工具，包括性能排行榜、基准测试结果整理及测试工具索引，用于从数据角度理解不同芯片与设备的性能表现，帮助你在对比与分析时获得更直观的参考依据。 隐私与原则 • 本地优先：App 核心功能完全在设备本地运行，无需登录即可使用。 • iCloud 同步：仅用于在你的设备之间同步数据，不收集、不分析任何个人信息，默认不开启。 • 体验优先：无广告、无推送、无后台唤醒，界面简约设计，信息结构清晰，专注于内容本身。 • 轻量设计：安装包体积小，不占用额外系统资源。 Device Lab，让复杂的硬件参数，从此一目了然。

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.
