GasTab

Ever wonder about your fuel costs or efficiency for each trip? Want to track fuel receipts or mileage for reimbursement? FREE lifetime access for early adopters like you!

GasTab is a FREE iPhone app that tracks fuel efficiency and what your driving really costs — trip by trip.

Plug in a BLE OBD2 adapter and GasTab records every drive. See route maps, distance, duration, fuel economy, fuel cost, cost per mile/km, and driving scores.

GasTab has something for every driver: • Watch every dollar at the pump — fuel cost and cost per mile/km for each trip; log fill-ups and odometer on the web dashboard • Drive for work — add a quick note, then use Trip Mileage on the web to mark work trips and export a CSV file for reimbursement • Love maps or exploring new roads — see a map of every drive and learn your road network • Eco-driver or hypermiler — compare fuel economy on the same routes and learn to drive more efficiently

Your trips stay on your phone by default. Web upload is optional. Lifetime web access is free for early adopters like you.

You need: • iPhone with GasTab from the App Store (iOS 26.2 or later) • BLE OBD2 adapter (tested: OBDLink CX, Veepeak OBDCheck BLE, Vgate iCar Pro BLE) • Gasoline or hybrid vehicle with an OBD2 port

Note: OBDLink CX does not work reliably with some GM and Ford vehicles — a Veepeak or Vgate is the safer first buy.
