Hello fellow EV owners and enthusiasts. I'm working on an app that uses the phone camera to scan drive computer read outs to automatically log session data before charging and could use some help.

I own a Nissan Ariya which shows a Since Charge log and would like to see what other drivers have available in their vehicles and what information could be gleaned from a simple snapshot.

From this screen on my Ariya, I'm able to capture:

- Mileage (mi)

- Starting SoC (%)

- Distance Driven (mi)

- Avg Efficiency (mi/kWh)

- Remaining Range (mi)

- Avg Speed

- Drive Time

- Temperature

If you have a single view that shows anything along these lines that you can share in a DM, that would be incredibly helpful.

Thank you!

WattLog is live! I built an Ariya-specific efficiency tracker—no more manual spreadsheets.

Hi everyone!

Some of you might recognize the name—I’ve been working with a group of r/NissanAriya testers over the last few weeks to refine WattLog, and today it’s officially live on the Google Play Store!

What is it?

I’m an Ariya owner myself and a UX developer. I got tired of trying to track my real-world efficiency and gas savings in clunky spreadsheets. WattLog uses your phone’s camera to "scan" your Drive Computer summary right before you charge.

How it works:

  • Snap & Sync: Point your phone at the dash. OCR happens entirely on your device—your photos never leave your phone.
  • Cost Comparisons: If you input your local charging costs, the app calculates exactly how much you’re saving compared to gas prices in your specific region.
  • Data Sovereignty: Your data is yours. You can download your entire log history as a CSV whenever you want.
  • Trends: It automatically generates insights on your mi/kWh and cost-per-mile trends over time.

The Roadmap (What's coming next):

  • Household Sharing: My #1 requested feature. My wife and I both drive the car; soon we’ll be able to contribute to the same vehicle log and see combined household stats via a "digital handshake."
  • Multiple Vehicle Tracking: Manage your whole EV fleet in one spot.
  • iOS Version: It’s in the works! My only iOS device is an old iPad, so I’m working on porting the logic as we speak.
  • API Integration: Proactive logging for other makes/models via direct vehicle APIs.

I want to thank the Redditors here who helped me through the 14-day beta. You guys squashed dozens of bugs and helped me circle the globe 116 times in simulated data!

Check it out here: WattLog on Google Play

I’d love to hear your feedback or feature requests. I’m building this for us, so tell me what you want to see next!

Lately the Nissan app has been sending me random notifications. Like that it started or stopped charging, while it's not plugged in. Or that my scheduled climate control is active... at 2 am. When it's not scheduled.

Anyone else experiencing this? Do you just ignore or turn off notifications?

A posted a few weeks ago about an app I'm developing to log charging data in my Ariya and I thought I would give a little update.

It looks like we are a few days away from the official release and I've been adding functionality to keep the testers busy. The latest addition is the Drive Summary... If you're logging your charges regularly, AND you capture how much you pay per kWh for the previous session, then the app will present you with the drive summary that estimates how much your drive costs you, per mile and total. And, if you're within the United States, this will be compared to an ICE vehicle. The backend is grabbing the current average cost of gasoline and can show that cost based on your region.
