Features

Your ride, your estimates.

CommuteUs learns from your own car's data, not a sticker average, and every fill-up sharpens its estimates.

Plan the trip first

Pick a destination and see the drive's distance, fuel, and cost before you leave, at the MPG your car actually gets on that kind of route.

Estimate your spending

Cost per mile, per drive, and per month, with a projection for the month ahead.

Fill-ups noticed for you

When the tank rises, CommuteUs spots the fill-up and asks you to confirm. Add the price and you're done.

Live on your Lock Screen

A Live Activity shows the drive's MPG, cost, and arrival, on your iPhone, in CarPlay, and on Apple Watch.

Ask Commute

Ask "How much did I spend on gas this month?" and get a straight answer, worked out privately on your iPhone.

Car health at a glance

Check-engine status, trouble codes, and battery voltage, read straight from your car.

How It Works

Three steps to a smarter estimate.

Start by hand, or plug in an adapter and let your drives log themselves.

Add your car

Read it from your car through an OBD-II adapter, or enter the year, make, and model. Official EPA ratings fill in the rest.

Drive

With an adapter, drives start and stop on their own, even when the app is closed. Fuel use comes from your engine's own readings.

Fill up

Each fill-up calibrates CommuteUs to your car, so estimates get closer to the pump with every tank.

Adapter

Hands-free with an adapter.

CommuteUs works with Bluetooth Low Energy OBD-II adapters that use the ELM327 command set. Plug one into the port under your dashboard, pair it once, and you're set.

  • Fits most gas cars sold in the U.S. since 1996
  • Uses Bluetooth LE: classic Bluetooth and Wi-Fi adapters won't connect to iPhone
  • No adapter? Log fill-ups by hand and still get your cost per mile

Commute Pro

Every trip, counted.

Pro logs your drives and fill-ups from your adapter automatically, so every trip is counted without opening the app.

Monthly or yearly, with a free one-week trial. Cancel anytime in Settings.

Privacy

Your data stays yours.

No accounts, no ads, no analytics, no tracking. Your cars, drives, fill-ups, and spending are stored on your iPhone, and we never see them.

  • Everything is stored on your device
  • Ask Commute runs on your iPhone
  • Vehicle lookups send only the year, make, and model
  • Diagnostic logs leave your phone only if you choose to send them
  • Clear your history, learning, or cars anytime
Your car, your drives, and your spending belong to you. They stay on your iPhone, and the App does not collect them.

Support

We're here to help.

Questions, a drive that looked wrong, or an idea? In the app, open Garage › Send Feedback, or email support@commuteus.app. Tell us what happened and roughly when, and we'll get back to you.

My adapter won't connect

Make sure it's a Bluetooth LE adapter, the car is on, and no other app is connected to it. Pair it from the app, not from iPhone Settings.

A drive wasn't recorded

Keep Bluetooth on for CommuteUs, and open the app once after installing it or restarting your iPhone.

Estimates look off

They may differ from your dashboard, which works out MPG its own way. CommuteUs learns from your fill-ups. Still off after three? Send us feedback.
