ad4car is a reliable, secure, and finanzamtkonform digital Fahrtenbuch (mileage log). The only hardware required is your iPhone - you can even leave it at home. Say goodbye to handwritten notes, unrecorded trips, and constant stress.

To use ad4car, you only need an active Bluetooth connection to your car. Every trip is automatically recorded, ensuring that only trips with your car are logged, excluding other vehicles like bicycles.

All data is stored exclusively on your device, eliminating the need for email sign-ups. Private trips can be censored, displaying only the mileage and date while keeping addresses hidden.

Uncategorized trips are easily categorized with a single click, and the export feature is finanzamtkonform, audited for compliance with tax office requirements.

• *Important Note**

Regularly export/save your trips in PDF format from the ad4car app. Perform data backups and transfer them to another storage device as we do not take responsibility for data loss.
