Bytetally
Bytetally is a macOS network monitor that shows per-app bandwidth usage and helps you track, limit, or block network activity.
What is Bytetally?
Bytetally is a native Mac utility for monitoring how much network data each app uses. It helps users see live upload and download activity, review usage over time, and understand which apps are responsible for traffic on their Mac. The app is designed for people who want clearer visibility into bandwidth use, including metered connections, hotspot use, shared networks, or troubleshooting unexpected data consumption. Bytetally also includes controls for limiting or blocking network activity, setting quotas, and exporting usage data in supported versions. It runs on macOS and focuses on on-device analysis, giving users a practical way to watch and manage network usage without relying on a web dashboard.

Safety overview
Status: Mostly safe
Bytetally is a network monitoring utility, so it is expected to observe network usage on your Mac and may request the access needed to measure or control app traffic. That behavior is consistent with its purpose. Its privacy model is user-friendly because the product states that analysis stays on your Mac and no account is required, but you should still review any network-control features before applying limits or blocks so you do not interrupt apps you rely on.
Recommendation: Keep Bytetally if you use it to watch data usage, troubleshoot bandwidth spikes, or manage metered connections. If you no longer need network monitoring or traffic controls, you can remove it like other Mac apps; doing so will simply take away its usage history and control features.
