ReserveGauge reads your live Codex and Claude Code limits straight off your Mac (the 5-hour and weekly windows), learns your usage rhythm, and projects the rest of your week. It accounts for your daily pattern, the hours you're asleep, and any recent spike, and forecasts your usage It also surfaces your banked Codex rate-limit resets and when they expire, and if you run more than one account, it remembers the others and shows their reset countdowns so you know when a maxed-out account frees up.
