NSguard 是 NSNode 室内环境监测设备的配套应用，帮助你集中查看设备上传的环境数据，了解不同空间的当前状态与变化趋势。 集中展示空气质量等级、甲醛、TVOC、eCO₂、温度和湿度数据，清晰了解当前室内环境状态。 查看最近 24 小时、7 天和 30 天的数据变化，并可分别查看不同环境指标。 支持绑定多台 NSNode，为设备设置“客厅”“卧室”或“办公室”等名称，并在不同设备之间快速切换。 首次添加设备时，通过蓝牙确认附近 NSNode 的设备身份。绑定完成后，日常环境数据将通过互联网从云端自动同步，无需保持蓝牙连接。 可以添加、重命名、切换或解除绑定设备，更方便地管理不同空间中的 NSNode。 使用说明： • 使用真实设备功能需要兼容的 NSNode 设备和互联网连接。 • 未连接设备时，可以通过演示模式了解应用的主要界面和功能。 • 蓝牙仅用于首次发现和绑定附近的 NSNode。 • 环境等级和传感器读数仅用于环境监测与趋势参考，不构成医疗诊断、安全认证或专业检测结论。

Verdict
The clearest difference is ads: NSguard at none against Radex's shown. NSguard also leads on update cadence (weekly vs every 2 months). Radex's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 26.0). On price and in-app purchases there is nothing between them.
