Speed-O-Meter Pro — GPS Speedometer with Steampunk Flair

Turn your iPhone into a stunning GPS speedometer with handcrafted steampunk instrumentation. Whether you're driving, cycling, or just curious about your speed, Speed-O-Meter Pro delivers real-time GPS data through beautifully animated gauges inspired by vintage brass instruments and glowing Nixie tubes.

TWO SPEEDOMETER STYLES

• Analog — A classic circular gauge with a sweeping needle, brass bezel, decorative rivets, and smooth arc animation. Scales automatically across four speed tiers up to aircraft speeds.

• Digital — Authentic Nixie tube display with warm neon glow, honeycomb mesh anodes, and stacked cathode layers, just like the real thing. Watch digits roll and glow as your speed changes.

Both styles feature dynamic speed tier icons that evolve as you accelerate — from a tortoise at rest, through walking, cycling, and driving, all the way up to airplane and beyond.

LIVE WEATHER AT A GLANCE

Current temperature, humidity, precipitation chance, and wind speed are displayed right on your dashboard — no need to switch apps. Weather data updates automatically using Apple WeatherKit.

NAVIGATIONAL COMPASS

A brass compass rose with smooth animated heading, cardinal direction readout, and degree display keeps you oriented wherever you go.

TRIP COMPUTER

Track your journey with distance traveled, average speed, maximum speed, and elapsed time. Start, stop, and reset with simple controls.

SHARE YOUR LOCATION

Share your current speed, heading, trip stats, and an Apple Maps link with one tap — perfect for letting someone know where you are and when you'll arrive.

APPLE WATCH COMPANION APP

Speed-O-Meter comes with a full Apple Watch app featuring both analog and digital displays. When paired with your iPhone, the Watch uses your phone's superior GPS for maximum accuracy. When on its own, it seamlessly falls back to the Watch's built-in GPS.

DESIGNED FOR EVERY ORIENTATION

Optimized layouts for portrait and landscape modes, with intelligent Dynamic Island adaptation that keeps controls accessible regardless of how you mount your device.

CUSTOMIZE YOUR EXPERIENCE

• Speed units: km/h or mph • Temperature: Celsius, Fahrenheit, or auto-match your speed unit • Appearance: Light, Dark, or System • Display style: Switch between Analog and Digital anytime

PRECISION GPS

Color-coded accuracy indicator shows your GPS signal quality at a glance — green for excellent, amber for moderate, with real-time accuracy in meters.

Built with care for drivers, cyclists, pilots, and anyone who appreciates beautiful instrumentation.

FREE WITH NON-INTRUSIVE ADS

Speed-O-Meter is completely free. A small banner ad appears in Settings, and a brief full-screen ad is shown after you complete a trip. Ads never appear on the main speedometer screen, and for safety, no ads are ever displayed while you are in motion.
