Field Twin

Field Twin

Field Twin is a phone friendly field log. It is for a person who drives to job sites and needs to record stops, receipts, and miles.

A map shows entries, traffic cameras, and road hazards. Buttons log miles and receipts, and a receipt reader fills in the entry from a photo. Search, history, spend, and mileage views look things up. Sign in syncs entries across phones. An Android app tracks trips and stops automatically and asks for odometer readings. End of day debriefs summarize the day. Daily miles shows each workday's start, end, and business miles, and GO gives turn by turn routes.

Latest change. 2026-10-31, v2026.10.31. Added GO navigation. The route banner sits below the tabs with zoom buttons under it, and a Google Maps button hands the destination to Google Maps. The bottom panel now stays above the phone keyboard.
