ReserveGauge

ReserveGauge is a native macOS menu bar app for developers using Claude Code and Codex. It reads live usage on your Mac, shows 5-hour and weekly usage, reset countdowns, recent history and activity state, then forecasts whether your current pace will run out before reset. Free shows live gauges, current usage, reset timing and history. Pro adds burn-rate forecasts, run-out estimates, pace guidance and what-if scenarios. The point is the question you ask before starting another coding session: at my current pace, will this fit before reset? Usage history stays local, with no app account or telemetry.
