What would petrol have cost?
Viametry compares your recorded charging costs with the same kilometres in a petrol car, at each week's pump prices from the European Commission. Try it with an example.
€1,220
a year less than a petrol car, on energy alone
Example with assumed prices: petrol €1.70 per litre at 7 l/100 km, electricity €0.30 per kWh at 17 kWh/100 km, mostly charged at home. In the app, your own charging bills and the weekly EU pump prices replace these.
What you get
Viametry reads the data your Tesla already records and turns it into a calm overview of your driving, charging and running costs.
Inspection, insurance, winter tyres and anything unusual, on one calm overview.
Superchargers as Tesla billed them, home charging at your tariff, public chargers at the price you save or enter.

On your phone
Viametry isn't in the App Store or Google Play. It's a web app: add it to your home screen once, and it opens full screen from its own icon, sends notifications and keeps itself up to date. Nothing to download or update.
Web app, not an app-store app
On iPhone and iPad, notifications work once Viametry is on the home screen (iOS 16.4 or newer). Other browsers on iPhone (Edge, Firefox) also add it through Share.
For business
Every drive lands in the logbook with its distance, route and time. You mark it business or private, add a purpose, and export it for your accountant.
Czech Republic
What your country asks forWe don't add the kilometres up into one percentage: each tax treats them differently.
AI assistant
Connect Claude, ChatGPT, Grok, Le Chat or Perplexity to Viametry and ask in plain words: what charging cost last month, which trips still need a purpose, what the car cost per kilometre. With your permission it does the paperwork too.
How much did I spend on charging during last week’s vacation in Italy?
Your Italy trip, 12 to 19 October: 9 charges and 214 kWh. EUR 81.20 so far for the 7 Superchargers. The 2 public charges at Lago di Garda (40.5 kWh) have no price yet.
Those two charged at 0.59 EUR per kWh. Update them.
Done: EUR 23.90 added to the two charges. The vacation’s charging came to EUR 105.10, about EUR 0.05 per kilometre.
