Whether you're keeping pace on the interstate, watching for a school-zone limit, or just curious how fast you're really going, Roadmeter gives you a clean, accurate answer at a glance. ROADMETER PRO The free version includes the digital dial, HUD mode, speed limit alerts, and one saved trip. Roadmeter Pro unlocks all dial styles and accent colors, unlimited trip history, motion analytics, and alternate app icons.
