AutoBuch : Fahrtenbuch

AutoBuch records every trip automatically and turns it into a logbook built to survive a German tax audit. No account. No server. Your trips stay on your phone. DRIVE, AND IT WRITES ITSELF GPS and motion detection start and stop every trip automatically in the background, no tapping required. If recording ever stops, the app tells you right away instead of silently losing a trip. CLASSIFY IN SECONDS Business, private, or commute — one tap sorts a trip. Bulk actions clear a whole day or week at once, and addresses are resolved to readable place names automatically. BUILT FOR A TAX AUDIT Every change is written as a new entry in a hash chain — nothing is overwritten. After the lock deadline, tax-relevant fields can only change with a documented correction. Before you export, the app checks for gaps in the odometer chain and missing fields. COSTS, ALL IN ONE PLACE Fuel, charging, service, insurance, tolls and more, each linked to the right vehicle. Costs feed straight into the comparison between the logbook method and the 1% rule. EXPORTS YOU CAN HAND OVER (WITH PRO) A logbook PDF with a verification hash, CSV with every field, and commuter-allowance and travel-expense reports for your tax return. Everything is generated on your device and shared from there. YOUR DATA STAYS YOURS No account, no server, no cloud copy. Everything lives in a database on your phone, plus a local backup. Location data is used only to detect trips.
