A complete walkthrough of the initial setup — what to fill in right from day one so every calculation (consumption, cost per km, comparison against a combustion car) is accurate from your very first session.
1 On the welcome screen, click Create account and enter your name, email, and password.
2 Check your email (including your spam folder) and click the confirmation link.
3 After logging in, you'll be prompted to set up your first database — enter a name (e.g. your car's name), your main currency, and your battery's usable capacity in kWh.
Before you start logging sessions, we recommend going through Settings and filling these in — the app works without them, but your numbers won't be accurate:
In Settings, enter your reference petrol and diesel consumption (L/100km) and their default prices — the app then calculates, for every session, what the same trip would have cost with a combustion car.
1 Go to Add Session.
2 Choose the charging type — AC (slow, home/street charger) or DC (fast, highway).
3 Enter the provider (PRE, Tesla, Ionity...), how many kWh you actually charged, the current odometer reading, and the price.
4 The app shows a live preview of your cost per km and combustion comparison as you type — so you can sanity-check the numbers before saving.
The Insights tab is the first thing you see after logging in. The key indicators:
| Indicator | What it means |
|---|---|
| Total energy | Sum of kWh across all logged sessions |
| Charging cost | What you've paid for electricity in total |
| Total cost (all-in) | Charging plus any flat-rate tariffs combined |
| Distance covered | Sum of km between consecutive sessions (see the settings above if this doesn't match your odometer) |
| Battery cycles | How many times you've "cycled" through a full battery's worth of capacity |
| vs. Petrol / vs. Diesel | How much you've saved (or lost) compared to a combustion vehicle |
| Purchase price | The vehicle's final price, based on your owner type |
| Cost per km (all-in) | Everything combined — purchase, insurance, service, charging — divided by km owned. The longer you own the car, the more the purchase price gets diluted |
In the Sessions tab you can filter by type (AC/DC), provider, month, or a custom date range — a summary above the table shows totals for whatever's currently filtered. Insights also includes a pie chart breaking down cost by provider.
All your data is saved automatically to the cloud — log in from anywhere and it's there. For peace of mind (or your own analysis in Excel), you can also download a full backup anytime from Settings → Export backup as an .xlsx file.
Usually because "Odometer at acquisition" isn't filled in under Settings — without it, the app only starts counting distance from your very first logged session, not from when you actually took ownership of the car. Fill it in and the numbers should line up (see section 2 above).
The app needs two points (two consecutive sessions) to calculate the distance between them. Your very first entry has no earlier point to compare against — either wait for a second session, or fill in "Odometer at acquisition" under Settings.
Yes — just log in with the same account on any device and your data syncs automatically.
Under Settings → Danger zone, you can delete a single database (vehicle) or your entire account, including all data — instantly and permanently.
