How to track a journey with your phone

Last updated 17/09/2026
Tap when you set off and tap when you arrive — Mighty works out the miles and creates the mileage claim.

Journey Tracker uses your phone to record a business journey for you. You tap once when you set off and once when you arrive. Mighty works out the miles and creates the mileage claim, so you don't need to remember postcodes or look up distances later.

If you'd like to know what a mileage claim is and how much you get for each mile, start with How to claim mileage for a business journey.

How it works

Journey Tracker uses GPS (the part of your phone that knows where you are) at two moments only: when you select Start journey and when you select End journey. It then works out the distance by road between those two places.

It does not follow you while you travel. So it doesn't drain your battery, and it works even if you lock your phone or lose signal on the way.

Because Mighty measures the road between your start and your end, the miles are for a direct drive. If you took a much longer route for a business reason, you can change the miles before you save.

Put Mighty on your home screen

You can add Mighty to your phone's home screen so Journey Tracker is one tap away.

  • iPhone: open Mighty in Safari, select the Share button, then choose Add to Home Screen.
  • Android: open Mighty in Chrome. When you see Install Mighty on your phone, select it.

Once Mighty is on your home screen, open it and select Journey Tracker on your dashboard or in the menu. On Android you can also press and hold the Mighty icon and choose Journey Tracker from there.

Letting Mighty use your location

The first time you select Start journey, your phone asks if Mighty can use your location. Choose Allow. Mighty only checks your location when you press Start or End.

Journey Tracker always records the journey for you, the person signed in. To add a journey for someone else, use the Mileage Claims screen.

See the route later

Mighty keeps the route with your claim. On a computer, open Expenses > Mileage Claims, select the three dots on the journey, and choose View route.

Common questions

What if Mighty can't work out the route?

If your phone has no internet when you arrive, Mighty can't measure the road. You'll see a message asking you to enter the miles yourself. Type the distance in Miles (one-way) and carry on. Your start and end points are still saved with the claim.

What does "Weak GPS signal" mean?

Your phone isn't sure exactly where you are. This often happens indoors. Move outside or near a window and select Try again. If you're happy with the position anyway, select Use this position anyway.

My phone says location is blocked

Your phone has been told not to share your location with Mighty. On an iPhone, open Settings, then Privacy & Security, then Location Services, and allow it for your browser. On Android, allow location for the site in your browser settings. Then select Try again.

I forgot to press End journey

Select Discard this journey, then add the trip by hand on the Mileage Claims screen. How to claim mileage for a business journey shows you how.

It says my account isn't set up to claim expenses

Each person needs permission to claim expenses. Ask your company's main user, or your accountant, to turn it on for you.

Why does it ask for an engine type?

You only see Engine type if your company is VAT registered or the car belongs to the company. Mileage, VAT and company cars explains which one to choose.
