Badger Maps and SalesRabbit bill $58–119 per rep, per month, forever — a 10-rep canvassing team is $7,000+/year before it proves a single door got knocked. Door Tracker runs the same route-verification job on a server you control: every rep’s phone pings every 5 minutes, the engine auto-clusters pings into stops, and duration alone tells you drive-by from doorstep. Introductory price is $49 — locked for the first 1,000 licenses, then $299 — and it never meters per rep.

• 5-minute GPS pings — Reps’ phones report location automatically in the background — no manual check-ins to forget.
• Auto stop-clustering — A haversine-distance engine groups consecutive pings into stops the moment a rep parks or lingers, with a configurable radius per team.
• Duration bands do the judging — Drive-by (under 30s), likely knock (30s–5min), extended visit (over 5min) — color-coded so a manager sees the shape of the day at a glance.
• Full-day route map — A connected polyline through every ping plus numbered, timestamped stop pins — click any stop for arrival, departure and duration.
• Team overview dashboard — Every rep’s time-in-field, stop count and average dwell for the day, one list, click through to any route.

Runs as a Windows desktop app or on any $5 VPS (Docker included).
