GlassWire
GlassWire is a network traffic monitor and personal firewall for viewing current and past activity and blocking suspicious or badly behaving apps. Its desktop analysis can organize usage by IP address or host, app, traffic type, and other categories. Alerts flag unusual network or app changes that could indicate malware, as well as unknown devices joining Wi-Fi. On Android, the app graphs data use by app, reports when apps access the network, and can block connections over mobile or Wi-Fi. GlassWire says Android app and data usage information stays on the phone and that the app itself uses no data. Free includes 24 hours of network history, one day of bandwidth history, and alert logs for the current day. The Personal Plan costs 2.99 USD per month when billed annually and provides unlimited network and bandwidth history and alert logs. Premium features include bidirectional firewall controls, custom profiles, Ask to Connect, and Lockdown Mode. The desktop download requires Windows 10 or later and supports x64 and ARM64.
