Hello everyone,  
I've been building an app [Speedometer: Driving Tracker](https://apps.apple.com/us/app/speedometer-driving-tracker/id6759611784), a CarPlay-supported driving tracker focused on trip history, analytics, and the overall driving experience across Apple devices. And it works with EV smoothly!

Recently, I added real-time OBD2 analytics support after many users requested deeper vehicle insights.

You can now view live OBD2 data directly on CarPlay, iPhone, iPad, Mac, and even Apple Watch (via Live Activity).

Some supported data includes:  
• Engine Load  
• RPM  
• Throttle Position  
• Fuel Usage  
• Coolant & Oil Temperature  
• Mass Air Flow  
• Intake/Ambient Air Temperature  
• And more

What I personally found most interesting during testing was being able to review how different driving styles affected engine behavior across an entire trip, not just while looking at live gauges.

The app also supports automatic trip recording using Siri Shortcuts automations when your OBD2 device connects.

One important thing:  
Every car exposes different OBD2 sensors, so available data can vary depending on the vehicle and adapter.

Beyond OBD2, the app also includes:  
• CarPlay trip tracking  
• 3D route playback  
• Speed-colored trip replay  
• Video recording with speed + map overlays  
• Fuel, maintenance, and expense tracking  
• Vehicle-based analytics & comparisons  
• iCloud sync across Apple devices  
• Privacy-first experience (no ads, no tracking, no signup)

The goal was never just to make another speedometer or gauge app, but to create a more complete driving companion ecosystem for drivers.

Honestly, this creates a very unique experience for car enthusiasts, especially CarPlay users, because very few apps go through this level of integration and approval process.

I would love feedback from fellow car enthusiasts here!
