Mileage, earnings, and expense tracking for gig workers. Clock in, log payouts by app, and have GPS track your miles while you work. Pick your car by year, make, model, and trim from EPA fuel-economy data, enter your gas price, and GigMeter estimates fuel from that vehicle's combined MPG. At clock-out, gas is logged as a real expense so you see take-home: net, net per hour, and net per mile. Not a generic mileage deduction. Reports for the day, week, month, and year. For iPhone and iPad.
