BurnBar

BurnBar on your wrist and in your pocket. This is the companion app for BurnBar on the Mac. Your Mac reads the usage logs your AI coding agents write locally and works out what they cost; this app shows you those figures when you are away from the desk. IMPORTANT: BurnBar for Mac is required. This app does not read any logs itself — an iPhone cannot see what your agents do on your Mac. It shows the summary your Mac publishes into your own iCloud, and nothing else. Both apps are one purchase. WHAT YOU SEE • Today at a glance: API-equivalent cost and tokens, with the current estimated 5-hour block • Your budget: how much is left, and whether you are on course • History: the last 30 days as a chart, plus this week, this month and all time • Models: what each model cost you, with estimated prices marked • Agents: how today splits across Claude Code, Codex CLI and Gemini CLI • Friends: the ranking from your Mac's friends group, read live so it is current even when your Mac is asleep • Optionally the estimated energy, CO₂ and water footprint ON THE WATCH Today's spend, your remaining budget and your place in the ranking — one glance, no phone needed. YOUR DATA STAYS YOURS Sync is off until you turn it on, on the Mac. The summary travels through the private area of your own iCloud account, readable only by your own devices. There is no BurnBar account and no BurnBar server. Nothing is written back, and no project names or file paths are ever included. Costs are API-equivalent list prices computed from local token counts. They are not a bill from your provider and not a reading of your subscription's limits.
