Switching Car Log Apps: Bring Your History from Fuelio, Drivvo, Fuelly, aCar, Road Trip or a Spreadsheet

The short answer

Export your records from your current app as a CSV file, then import that file into CarStamp. CarStamp recognizes the exports of Fuelio, Drivvo, Fuelly, aCar and Road Trip, so the dates, mileage, amounts and costs land in the right places without mapping any columns. Any other app's CSV works too: you only say which column is which. Importing is free.

I make CarStamp, so read this with that in mind.

CarStamp is free for one car, with no account: download it on the App Store or see what's free.

Step by step

1. In your current app: export your records as a CSV file. Where to find the export in each app is below.
2. Save the file to Files or iCloud Drive on your iPhone, iPad or Mac. Email it to yourself or use Google Drive or Dropbox if it starts on another device.
3. In CarStamp: add your car. A name is enough to begin.
4. Import: open the car's overview and tap Import from CSV…, then pick the file. It is also at the bottom of the add menu, and on a Mac in File, Import CSV…. If the file holds several cars, CarStamp asks which one to import.
5. Check and import: look over the preview and the categories, then import.

For several cars, add each car in CarStamp and import its records into it. If letters look wrong in the preview, choose another encoding. More is on the support page, under Importing from another app.

App by app

Fuelio

Export: use Fuelio's CSV export. Fuelio's help puts it in Settings, Backup, Export CSV.

What comes over: fill-ups with the odometer, amount of fuel, price per unit, total, whether the tank was filled and the city, with charging kept as charging. Costs come over with Fuelio's own category names. Miles or kilometers and liters or gallons are read from the file. Fuelio's cost templates and income entries are left out.

Drivvo

Export: use Drivvo's CSV export.

What comes over: refuelings (charging stays charging), expenses and services, each with the date, odometer, cost, place and notes. A file with several cars is fine: CarStamp asks which car to import. Files exported with Drivvo in English, Portuguese, Spanish, Polish, Italian, German or French are all recognized.

Fuelly

Export: on the Fuelly website, open your car's page and export your fuel-ups.

What comes over: fill-ups with the date, odometer, gallons or liters, price per unit, the station brand and notes; the total is worked out from the amount and the price, and partial fill-ups stay partial. Fuelly's export holds fill-ups, so services and other costs are added in CarStamp.

aCar

Export: in aCar on Android, use the CSV (Excel compatible) export, not aCar's backup file.

What comes over: fill-ups, services (with what was done, such as "Oil Change, Tire Rotation") and expenses. Every record names its car, so CarStamp asks which car to import. Moving from Android to iPhone? The aCar guide walks through it.

Road Trip

Export: use Road Trip's CSV backup (Road Trip can also save it to Dropbox). It holds one car per file.

What comes over: fuel records, with charging in kWh kept as charging, and maintenance records as services with their description, cost and location. Partial fills stay partial. Road trips, the tire log and valuations are left out.

From a spreadsheet or any other app

Kept your car's costs in Excel, Numbers or Google Sheets, or used an app that isn't listed above? Save or export it as a CSV file and import it the same way.

• Columns: CarStamp guesses what each column holds from its header (English, Bulgarian or German headers), and you check or change it: date, mileage, amount, currency, category, title, quantity, unit price, full tank, station or workshop, and notes.
• Categories: each category in your file goes where you choose: fuel or charging, a service, an expense category such as insurance or parking, mileage only, or skipped.
• The file's format: whether the first row is a header, the decimal separator and the date format are set for you and can be changed.
• Workshop invoices: turn on Rows with the same date and mileage are one service, and the lines of an invoice become one service, with part numbers, pieces or hours, and discounts.
• Duplicates: rows that match records you already have are marked as possible duplicates and left out unless you include them, so importing the same file twice doesn't double your history.

Each row needs a date and either an amount or a mileage.

After the import

Your history arrives in an app built for iPhone, iPad, Mac and Apple Vision Pro:

• Fuel economy from day one: every fill-up comes with its odometer and amount, so your average fuel use and cost per mile or km are there straight away.
• Reminders for maintenance by date or mileage, and for renewals such as insurance, inspection and registration.
• Services line by line from now on: every part, part number and labor line.
• No account, no ads, no data collected. Your records stay on your devices; with Pro they sync across your devices through your own iCloud.

Questions about switching

Which apps can CarStamp import from?

CarStamp reads the CSV exports of Fuelio, Drivvo, Fuelly, aCar and Road Trip without mapping columns, and any other CSV file once you say which column is which.

Does importing cost anything?

No. Importing is free, and CarStamp is free for one car, with unlimited records.

Will my fuel economy history still be right?

Yes. Fill-ups come over with their odometer readings and amounts, and partial fill-ups stay marked as partial where the other app's file records them, so CarStamp works out fuel use from the same records.

What if I import the same file twice?

Rows that match records you already have are marked as possible duplicates and left out unless you include them, so your history isn't doubled.

Can I import on a Mac?

Yes. In CarStamp on a Mac, choose File, Import CSV…, and pick the file.
