NetCheckup: Network Analyzer

NetCheckup is a network diagnostics tool for field technicians and everyday users. It shows everything Android makes available about your connections, and when a value can't be read, it tells you why.

Wi-Fi
• Current connection: signal, link speed, band and channel, Wi-Fi 6/6E/7 (including MLO), security type, IP, gateway, DNS and more.
• Live charts for signal, link speed and latency (router, Cloudflare, Google), marking when roaming and band changes happen, with the access point and signal before and after each switch.
• Nearby access point scan: channel width, security, 802.11k/v/r, vendor; 2.4/5/6 GHz spectrum view and channel usage.

Mobile network
• Multiple SIMs, carrier, 5G/LTE display type, service state, full LTE/NR signal fields with charts, serving and neighboring cells.

Speed test
• Powered by Cloudflare: idle latency, jitter, download, upload and loaded latency; choose Wi-Fi or mobile data.

History
• Save measurements, compare two records side by side, and export to JSON or CSV (optionally mask Wi-Fi names and identifiers). Records stay on your phone.
