See Mac battery drain in the menu bar

macOS shows battery percentage, but not always drain rate — how fast your MacBook is losing charge right now. Fathom Air is a free menu bar app from Chopsticks HQ that surfaces drain-focused stats locally.

What Fathom Air does

• Menu bar readout oriented around battery drain / usage
• Local-first — no account, no product telemetry
• Free download from chopstickshq.com

Fathom Pro (optional upgrade path)

Fathom Pro adds local weather (Open-Meteo) and optional AI chat using your own API keys. Still free — unlock with a key from the vault or homepage easter egg.

Pair with MacBar

Many users run Fathom alongside MacBar for CPU, temperature, and RAM in the menu bar while Fathom focuses on power behavior.
