// WHY IT EXISTS
On a mobile hotspot or a metered plan, the question "where did my data go this month?" is surprisingly hard to answer. macOS's built-in Network Utility only shows live speed. Third-party tools tend to be expensive, send your usage to a server, or both. 1 Bit Data is the small tool that should have come with the OS: live, local, honest, with the same terminal aesthetic as everything else from this studio.
// free · open source (MIT) · 10 MB // Developer ID signed + Apple notarized — Gatekeeper will not warn
// INSTALL
Download the .dmg above.
Open it, drag the app into Applications.
Launch — first run may ask permission to monitor network activity. Grant it.
// NOTE: 1 Bit Data is distributed through GitHub Releases rather than the Mac App Store. This is intentional — nettop access is incompatible with App Store sandboxing. The binary is signed with a Developer ID and notarized by Apple.
