Tachography Driver Card Reader

Tachography is a simple, fast app for downloading and reading data from a digital tachograph and from a driver card. Download straight from your phone, see the records laid out clearly, and keep them as a standard .DDD file — no computer, no internet.

NO EXPENSIVE EQUIPMENT NEEDED
Downloading from a tachograph needs no download key and no fleet software costing thousands. Your phone and its Bluetooth are enough. For a driver card, an ordinary USB smart-card reader will do — nothing tachograph-specific.

TACHOGRAPH OVER BLUETOOTH
• Downloads the vehicle unit's data straight over Bluetooth
• Downloads a driver card inserted in the tachograph as well
• Progress shows what is being read and how much has arrived
• Saves a standard .DDD file to share or archive
• Tracks the 90-day tachograph download deadline
• Tested on Continental VDO units with firmware V4141

DRIVER CARD
• Reads the card through a USB reader (USB-OTG / CCID) or through the tachograph
• Shows driver identity, driving licence details and card validity
• Breaks activities down by day: driving, work, availability, rest
• A colour timeline for each day at a glance
• Overview of the vehicles used (plate, odometer, period)
• Border crossings and loading/unloading records
• Tracks the 28-day card download deadline with a countdown and a warning

WHAT YOU SEE IN THE DATA
• Events and faults recorded by the tachograph, driving without a card included
• Activity breakdown per day, separately for driver and co-driver
• Calibrations, seals, constants and the vehicle unit's own identity
• Downloads grouped by vehicle

PRIVACY FIRST
All data stays on your device. The app sends nothing of its own accord — the one exception is a diagnostic record after a failed download, and it goes only if you confirm it yourself. No advertising, no tracking, no account. Your files stay entirely yours.

WHO IT IS FOR
For drivers, hauliers and anyone who needs to download and check tachograph and driver card data regularly under EU rules.

TRY IT WITHOUT ANY HARDWARE
A built-in "Demo User" card lets you explore the features with no reader and no vehicle.

MORE FEATURES
• Czech, Slovak, Polish, German and English
• Light and dark theme
• Choice of time base (local time or UTC)
• Diagnostic log for troubleshooting

SUBSCRIPTION
The first 30 days give you the whole app. After that, downloading new data from the tachograph and the driver card needs a subscription; records you have already downloaded stay available without one. Subscription and payment go through Google Play.

NOTE
This app is an aid and does not replace your legal obligations to download, evaluate and retain tachograph data. Always verify the data shown.
