# TollTracker

A point-to-point speed-camera alert for drivers in Bulgaria: it calculates your average speed on camera-monitored stretches in the background and alerts you before you go over, with no navigation app needed

**$16k** /mo verified revenue (payment-platform checked)

Why it's an opportunity

When a new rule takes effect, drivers across the country start worrying about zero-tolerance tickets in the same week. Mainstream navigation apps only draw a line and don't do the math for you in the background.

Why it's blowing up

Starting 11-01 daily revenue jumped from a couple hundred dollars to $1,000–2,200, with nearly 400 more subscriptions a day; who sparked that spike is unknown. This week it's cooling: daily subscription adds fell to 50–60, and its overall chart rank slid from #1 to #56 over the week.
