The best contractor office is the one in your pocket.
You're on a job site, in a truck, or on a ladder when the next lead calls. You need to capture information fast, generate a professional estimate before you leave the driveway, and attach a photo of the damage before you forget what you saw. This guide covers every field tool a solo contractor needs — all in one app.
Capture field details when typing isn't possible.
Contractors are frequently on ladders, in crawlspaces, or in trucks when they need to capture information. Voice notes attach directly to the lead card in the activity log — so the recording is there when you sit down to write the proposal, not buried in a separate voice memo app.

Field contractors need tools that work in the field.
Most estimating apps were designed for an office. They're slow to load, require internet, and don't connect to your lead tracking or mileage. A contractor on a job site needs something that works instantly, stores everything locally, and connects the estimate to the lead it was for.
