Chain the stops you actually drove — Milechain pulls the most reasonable route from Apple Maps and does the deduction math. No GPS tracking, no battery drain.
Tap saved places or paste an address. Each stop links to the last — that's your day.
Milechain proposes the most reasonable route from your map service — override any leg with one tap.
Weekly, monthly or yearly summaries land in your inbox with an accountant-ready CSV.
One tap on your wrist: current location or a saved place will chain straight onto today, with the Smart Stack keeping your running total in view — no phone required. Coming in a future update.
Your trips live on your iPhone and sync through your own iCloud. There's no Milechain account, no server, and nothing for us to sell — which is exactly the point of a tax record you can stand behind.
