What litr does
Practical vehicle records, without the clutter.
Start with a fill-up, then let the rest of the picture build naturally: consumption, costs, maintenance, supporting documents, and better decisions on the road.
Keep the proof nearby
Scan a pump display or receipt, attach documents to entries, and export receipts or backups when you need them.
Find worthwhile fuel stops
Compare nearby prices, consider the detour, and plan a route with fuel stops that make sense for your vehicle.
Use the car screen safely
CarPlay shows nearby prices, route-aware stops, and station details, then hands directions to your preferred maps app.
Share a vehicle, not your account
Choose a vehicle to share through iCloud. Invitees can collaborate on its records without receiving access to unrelated vehicles.
Stay in control of your data
Keep local backups, export selected vehicle data, and decide when a vehicle is shared through iCloud.
Fuel price coverage
Official public price sources, where we support them.
litr currently provides official fuel-price coverage in four countries. Availability and fuel types depend on the source published by each country. More countries are planned.

Privacy policy
Your vehicle data stays yours.
What litr stores
litr stores the vehicle information, fuel and maintenance entries, optional receipt documents, and optional location details that you choose to record. This information is used to provide the app's features.
iCloud sharing
Vehicle sharing is optional. When you share a vehicle, the data for that vehicle is stored in iCloud and made available to the people you invite. You can stop sharing at any time from the vehicle's sharing controls.
No advertising or tracking
litr does not use advertising networks or sell personal data. It does not use data to track you across apps or websites.
Permissions
- Location is optional and is used to show nearby prices and to help you record a station location.
- Camera is optional and is used to scan receipts, odometers, and pump displays.
- Notifications are optional and are used for a CarPlay-to-phone handoff when you choose an action that must finish on the phone.
Retention and deletion
Your data remains on your device and, where sharing is enabled, in the associated iCloud data store until you delete it or stop sharing. Removing the app does not necessarily remove data already stored in iCloud. Export a backup before deleting data that you may want to keep.

Support
Help when you need it.
Why are fuel prices unavailable?
Fuel-price coverage is currently available in Spain, Portugal, France, and Italy. Check that location access is enabled if you want litr to select the local source automatically, then refresh prices from the map.
How does vehicle sharing work?
Open a vehicle's sharing controls, create an iCloud invitation, and send the invitation link to the person who should collaborate on that vehicle. Sharing is optional and can be stopped by the owner.
Can I keep a backup?
Yes. Settings includes backup and data-export tools. Keep exports somewhere safe before moving devices or deleting app data.
What does CarPlay support?
CarPlay is designed for glanceable fuel-price comparison, route-aware fuel stops, station details, and directions handoff. Detailed entry, receipts, and vehicle setup stay on the phone.
