$10 off ova, the macOS bandwidth monitor

ova is a minimalist macOS menu bar app that shows real-time and historical network usage per app. Helper processes fold under their parent, so Arc and its twelve helpers count as one row rather than thirteen. History lives in a local SQLite file with raw, minute, hour and day rollups, which is how it keeps months of trends without a hundred-megabyte log. Idle CPU stays under 0.3% on Apple Silicon because it streams nettop once and parses incrementally. Nothing leaves your machine: no telemetry, no analytics, no servers. It is Swift and AppKit, notarized by Apple, and about 3 MB. The list price is $19. Paste LAUNCH at checkout and it comes off $10, so you pay $9. One time, with lifetime updates and a 14-day refund. Requires macOS 14 or later. Apple Silicon and Intel.
