- From the menu bar, you can check session 5h / weekly total / weekly Sonnet usage rates.
- It provides 80% / 95% alerts, a Calendar reminder for the next weekly reset, usage trend charts, per-model cost estimates, and a diagnostics export feature.
- It also comes with a token-opt hook that reduces memory unrelated to the project, which the author says saves about 80,000 tokens per week.
- The source is released under the MIT license, and it can be built with xcodegen + Xcode 16 + SwiftUI 6 + GRDB.swift.
