Odo is a simple mileage and expense tracker for anyone who drives for work - delivery drivers, rideshare drivers, realtors, contractors, and the self-employed. MILEAGE, WITHOUT THE SURVEILLANCE Type your start and end odometer readings and Odo works out the distance. Mark each trip business or personal with one tap. There is no GPS trail and no automatic trip detection - Odo records a single location only at the moment you save a record, so each entry shows where it happened without following you around. Miles or kilometres, set per vehicle. VEHICLE EXPENSES IN ONE PLACE Log every cost tied to the car: - Fuel, in gallons or litres, with the price per unit worked out for you - Tolls and parking - Maintenance and repairs - Car washes - Anything else, under Other Every expense belongs to a vehicle, so you always know what that car really costs. REPORTS READY FOR TAX TIME Set your mileage rate and Odo calculates the deduction. Export a clean CSV or a formatted PDF whenever you need one - for a tax return, an expense claim, or reimbursement. Amounts follow your currency's own conventions, so the numbers read correctly wherever you are. MORE THAN ONE VEHICLE Cars, vans, trucks - each keeps its own units, odometer and history. MONTHLY SUMMARY Distance driven and money spent, at a glance, with business and personal separated. BUILT TO STAY OUT OF THE WAY No account. No sign-up. No ads. No subscription.
