Common questions

How accurate are the estimates? They are estimates. Real charging varies with temperature, the car's battery and the charger. The slowdown near full is a simple approximation, not a measurement. The "About these estimates" screen in Settings explains how each number is worked out.

Where are my numbers saved? Only on your device, and only if you turn on "Remember my inputs" in Settings. Turning it off erases them.

Why did the numbers change when I switched units? They did not. The app keeps what you typed in miles, US mpg and miles per kWh and shows it in the units you pick.

How does time-of-use pricing work? Turn it on in Settings, then set the price schedule. The Electricity price field on the Charge page is replaced by the schedule, and a Start at row sets when charging begins. If you do not enter a charger speed, the cost uses the day's average price. The schedule covers every day the same way.

How are charging stops and CO₂ worked out? Both are estimates. A charging stop is assumed to add about 70% of the battery's range, and CO₂ counts only what the gas car's tailpipe would emit, using the EPA's 8.887 kg per US gallon.

Can I use it with Siri or Shortcuts? Yes. Ask how long to charge, how much it will cost, or how far you can go.
