Transition your dashboard into a clean, distraction-free cockpit. When placed on your mount, CityLine automatically shifts into a gorgeous, true-black Screensaver HUD. Featuring high-contrast typography, customizable Commuter and Explorer layouts, and dynamic pixel-orbiting sweeps to eliminate OLED burn-in.
Automotive Kalman Squelch Filter Model
Traditional GPS trackers keep your screen awake, draining your battery and causing your phone to overheat on the dashboard. CityLine uses hardware-accelerated, event-driven listeners that wake the CPU only when you actually move. Track boundaries in the background for hours while keeping your phone cool.

IRS Write-off formula
Stop guessing your business miles. CityLine automatically logs your commute distances in an offline, on-device ledger. Flag trips as Business or Personal with a single tap. At tax season, compile and export secure, IRS-compliant CSV reports instantly.
Keep your eyes locked on the road. When crossing city or county lines, CityLine can announce transitions using natural voice synthesis (e.g., "Entering Pasadena"). For silent drivers, the app securely wakes your locked screen with a beautiful, temporary full-screen notification.
CityLine adapts to your driving habits. Whitelist your car's Bluetooth system, and the app will automatically launch the speedometer HUD and start recording the second your phone pairs with your vehicle. No buttons to press, no forgotten drives.
*Requires background location set to "Allow all the time" for native auto-launch triggers.
Simple pricing. No recurring traps, no forced billing.

At Buitron Inc., we believe your location history belongs to you. CityLine calculates all geofences, speeds, and municipal crossings locally on your phone's hardware. Your coordinates are never tracked, collected, sold, or shared with third-party advertising profiles. Your drive is your business.
