See your speed. Make it yours. Speedometer puts your current GPS speed front and centre with large digits and a clean display. Use it on iPhone or iPad, or check your speed from your wrist with the standalone Apple Watch app. YOUR SPEED AT A GLANCE • Choose km/h, mph, knots or m/s. • See GPS status when the signal is weak or unavailable. • Use the iPhone and iPad display in portrait or landscape. CHOOSE YOUR DASHBOARD On iPhone and iPad, choose G-force, trip statistics or no module for a simple speed display. Change your choice in Settings or explore the options in the interactive introduction. YOUR TRIP IN NUMBERS See top speed, moving average, distance and time in motion. Stops are excluded from the average. Your totals stay saved between app launches and module changes until you reset them. A confirmation helps prevent accidental resets. Trip measurement runs while the app is open in the foreground with reliable GPS, regardless of your selected module. Measurement pauses in the background, during the introduction or when GPS is unreliable. Gaps are not counted as distance or time. A DISPLAY THAT FITS YOU Choose from five colour themes and four digit styles. Follow your device’s light or dark appearance, or keep the app always light or always dark. YOUR SPEED ON YOUR WINDSHIELD HUD mode mirrors your speed and selected module so their reflection in your windshield reads the right way round. Place your device securely on the dashboard with the screen facing the glass, keeping your view clear. Reflection visibility depends on the windshield, screen brightness and ambient light. Set it up while parked. EXPLORE MOTION On iPhone and iPad, view current and peak G-force alongside roll, pitch and yaw. Measure overall acceleration or an individual device axis. Reset the peak and orientation reference whenever you need to. Motion features require an available device motion sensor. SPEED ON YOUR WRIST The Apple Watch app measures speed independently of your iPhone. Choose your unit on the watch and glance at your speed while walking, running, cycling or boating. Trip statistics and dashboard modules are available on iPhone and iPad. GET STARTED YOUR WAY An interactive introduction helps you explore the controls and personalise the display. You can revisit it from Settings. On iPhone and iPad, add a Siri shortcut for your current speed. Speed measurement requires location access and a usable GPS signal. Keep your attention on your surroundings and adjust the app only when it is safe to do so.

Diese App zeigt die aktuelle Geschwindigkeit an, mit der das iPhone bzw. iPad gerade bewegt wird. Die obere, zentrale Anzeige erfolgt entsprechend des aktuellen Ortes, d.h. z.B. in km/h in Deutschland und in Meilen pro Stunde in den USA. Zusätzlich wird die in den vier Feldern darunter die Geschwindigkeit in den vier Einheiten Kilometer pro Stunde, Meilen pro Stunde, Knoten und Meter pro Sekunde angezeigt. Durch einen Touch auf eines dieser vier Felder wird die Einheit der oberen, zentralen Anzeige entsprechend umgeschaltet. Zusätzlich wird die Genauigkeit der Geschwindigkeitsanzeige angegeben, z.B. "±0,72 km/h". Woher kommen die Daten?  Die angezeigte Geschwindigkeit und die zugehörige Genauigkeit werden in dieser Form von Apple zur Verfügung gestellt und sind nicht nachbehandelt. Die angezeigte Geschwindigkeitsgenauigkeit kann sehr variieren. Apple macht keine weiteren Angaben zu dieser Größe. Der kleinste Wert den ich bisher sehen konnte war ±0,72 km/h bzw. 0,2 m/s bei Fahrt in ebenem, freiem Gelände. Je nach Umgebungsbegebenheiten kann dieser Wert deutlich größer sein: Z.B. hatte ich schon Werte von über 10 km/h bei einer Geschwindigkeit von 80 km/h auf einer Landstraße. Die tatsächliche Genauigkeit war dabei aber augenscheinlich wesentlich besser, als es der Zahlenwert vermuten ließe. Diese App ist ein Hobbyprojekt und Open Source. Der Code ist auf Github einsehbar (https://github.com/UPetersen/Uwes-Tacho/tree/main).
