Why don't I see my MPG yet?
Efficar measures from one full tank to the next, the most accurate method there is. Fill the tank, log it, and your efficiency appears after your next full fill-up. Top-ups in between are added to the next full one. Electric cars work the same way, from one charge to your usual level to the next.
Units and currency
Pick MPG, UK MPG, L/100 km or km/L when you start, and fine-tune distance, fuel and electric units any time in Settings. Your log is kept in kilometres, litres and kWh, so switching never changes it. Costs use your region's currency; you can choose another in Settings (it relabels, it doesn't convert).
Efficar Pro
The free version shows your last 30 days. Pro shows your whole history and adds more vehicles, service reminders, widgets and CSV export. iCloud sync is free for everyone, so your log comes back on a new phone. Nothing you log is ever deleted, subscribed or not. Manage or cancel your subscription in the iPhone Settings app, under your name, then Subscriptions.
