FahrtenbuchSupport and help
Answers to common questions about the Fahrtenbuch app. If your question is not here, write to us.
Why are trips or parts of a route missing?
Usually the phone stopped the recording during the trip: by restarting, by closing the app, or through a battery saver. If you open Fahrtenbuch while a trip is running, the app resumes recording. A trip with a gap is marked “GPS-Lücke – km bitte mit Tacho prüfen” (GPS gap – please check the km against the odometer); then enter the odometer reading. Please check:
- iPhone: Settings → Apps → Fahrtenbuch → Location → choose “While Using the App” and turn on “Precise Location” (depending on your iOS version: Settings → Privacy & Security → Location Services → Fahrtenbuch). “Always” is not needed. Do not close the app in the app switcher during a trip. Low Power Mode can limit recording.
- Android: Settings → Apps → Fahrtenbuch → Permissions → Location → choose “Allow only while using the app” and turn on “Use precise location”. Under Battery, set Fahrtenbuch to “Unrestricted”; on Samsung also add Fahrtenbuch to “Never sleeping apps” under Battery → Background usage limits. The wording differs between manufacturers. The “Recording your trip” notification shows that the trip is being recorded.
- Start the trip with “Start trip” before you drive off. In this version Fahrtenbuch does not detect trips automatically.
- A trip without GPS data is not saved. The app tells you when this happens.
How do I export my logbook?
In Fahrtenbuch, open Reports and tap “Export & send” (also under Settings → Export data). Choose PDF or CSV and the period, then tap “Export”. Your phone’s share sheet opens: send the report by email, for example to your tax advisor, or save it to Files.
The report is created on your phone. A fuel or electricity note that you entered for a trip appears in the CSV file in the “Verbrauch” column. We do not receive the report.
The report is always in German so that the German tax office can read it.
How do I move my logbook to a new phone?
Install Fahrtenbuch on the new phone and sign in to your account. Your logbook is stored in your account and is loaded onto the new phone. Entries that the old phone could not sync yet are, until then, only on that phone.
You can use the same account on several phones; Fahrtenbuch syncs the logbook between them.
Play it safe: export your monthly reports as PDF or CSV and keep them before you switch phones.
How do I fix a trip with the wrong category?
For 7 days after a trip ends you can change its category and details directly. After that the entry is locked. Open the trip, tap “Record a correction” and enter a reason. The original entry stays visible in the history.
Do I need an account?
Yes. You need an account to use Fahrtenbuch. You sign in with Apple, with Google or with a code sent by email; there is no password. On iPhone, Apple’s own sign-in sheet opens; signing in with Google, and with Apple on Android, runs in the phone’s browser.
Does Fahrtenbuch work offline?
Recording trips works without internet. Classifying and correcting trips and exporting reports also work without a connection; such a report carries the mark “Provisional – not synchronised” (printed in German as “Vorläufig – nicht synchronisiert”; on every page of the PDF, in the first line of the CSV file) until the phone has synced. Fahrtenbuch syncs all entries with your account as soon as the phone has a connection again. Address lookup needs your phone’s address service and therefore a connection. Offline, the app keeps the start and end as coordinates without a street address.
How do I delete my account or my data?
You delete your account in the app or by email. This deletes your data from our server, and we cannot restore it; export your monthly reports first and keep them. If you only delete the app on your phone, your logbook stays in your account.
A backup of your phone (iCloud, Finder, Android backup) may still contain a copy of the app data.
The individual steps are on the Delete account page.
