How to Choose the Best Mileage Tracker App
There is no single best mileage tracker app for everyone. The best app for you depends on how you work, how many journeys you make and whether you use a calendar. This guide helps you choose.
Why "best mileage tracker app" is the wrong question
Search for "best mileage tracker app" and you will find dozens of listicles declaring different apps the winner. But the truth is that the best app depends entirely on how you work.
A care worker who visits ten patients a day needs a different app from a consultant who visits two clients a week. A sole trader who lives in their calendar needs a different app from someone who prefers paper logs. And someone who wants automatic GPS tracking needs a different app from someone who values privacy and battery life.
Instead of asking which app is best, ask which type of mileage tracker is best for you. This guide breaks down the main types, compares them honestly, and helps you choose.
The five types of mileage trackers
Mileage trackers fall into five broad categories. Each has its strengths and limitations, and the right one for you depends on your work pattern, your preferences and your budget.
Understanding these categories is the first step to choosing the best mileage tracker app for your needs. There is no wrong choice — only the choice that fits how you work.
GPS-first trackers
Detect journeys automatically using your phone's GPS. No journey missed, but battery drain and privacy considerations.
Calendar-based trackers
Read appointments from your calendar and calculate mileage between them. No GPS needed, but requires calendar use.
Manual mileage logs
Enter each journey by hand. Simple and private, but time-consuming and easy to forget trips.
Spreadsheet tracking
Record mileage in Excel or Google Sheets. Free and flexible, but no automation and high maintenance.
Accounting software features
Built into Xero, QuickBooks or FreeAgent. Convenient if you already use the software, but often basic.
How it works

GPS-first mileage trackers
GPS-first mileage trackers use your phone's location services to detect when you are driving and record the route automatically. You do not need to remember to start or stop tracking — the app detects journeys for you.
- Strength: every driving journey is captured, including trips you forgot to log.
- Strength: no manual entry required for each journey.
- Limitation: battery drain from continuous GPS use.
- Limitation: privacy concerns — the app tracks all driving, not just business.
- Limitation: you still need to classify each journey as business or personal afterwards.
- Best for: people who make many journeys and want automatic capture, and who do not mind battery drain or location tracking.
Calendar-based mileage trackers
Calendar-based mileage trackers read the appointments already in your Google Calendar or Microsoft Outlook and turn them into mileage records. If you use a calendar for work, the information you need for mileage records — the date, the location and the business purpose — is already there.
- Strength: no battery drain — no continuous GPS tracking.
- Strength: no privacy concerns — the app only reads calendar appointments, not your location.
- Strength: no manual entry for each journey — your calendar does the work.
- Strength: your appointment title becomes the business purpose automatically.
- Limitation: only works for appointments with locations — ad-hoc journeys need manual entry.
- Best for: people who already use Google Calendar or Outlook for work and want to avoid GPS tracking.
Manual mileage logs
Manual mileage apps ask you to enter each journey by hand: the date, the start, the destination and the distance. Some calculate the distance for you from postcodes; others ask you to look it up.
- Strength: simple and fully controlled — you only record what you want.
- Strength: no battery drain, no privacy concerns, no location tracking.
- Limitation: time-consuming if you make many journeys.
- Limitation: easy to forget trips, especially at the end of a long day.
- Best for: people who make few journeys, or who want to record only specific trips.
Spreadsheet-based mileage tracking
Many sole traders start with a spreadsheet — Excel or Google Sheets — to record mileage. It is free, flexible and requires no new software. But spreadsheets have significant limitations for mileage tracking.
- Strength: free — you already have the software.
- Strength: fully customisable to your needs.
- Limitation: no automation — you enter every journey by hand.
- Limitation: no distance calculation — you look up or estimate every route.
- Limitation: no HMRC rate tracking or 10,000-mile threshold automation.
- Limitation: easy to forget journeys, hard to maintain over a full tax year.
- Best for: people who make very few journeys and are comfortable with spreadsheets.
Accounting software mileage features
Some accounting software — including Xero, QuickBooks and FreeAgent — includes basic mileage tracking features. If you already use one of these for your accounts, the built-in mileage tracker may seem convenient.
- Strength: integrated with your accounting — no separate export step.
- Strength: no additional software to learn.
- Limitation: often basic — limited tracking methods, no calendar integration.
- Limitation: you are locked into that accounting software's ecosystem.
- Limitation: may not support the tracking method that suits your work.
- Best for: people who already use the accounting software and only need basic mileage recording.
How to choose: factors to compare
When comparing mileage tracker apps, consider these factors alongside your work pattern:
- Ease of use: how quickly can you record a journey? Is the interface clear and simple?
- Automatic tracking: does the app capture journeys without manual input? GPS, calendar or both?
- Battery usage: if the app uses GPS, how much battery does it drain?
- Privacy: does the app track your location continuously, or only read calendar appointments?
- Calendar integration: can it read appointments from Google Calendar or Outlook?
- Multiple stops: can it calculate mileage for multi-stop journeys?
- Mileage reports: does it produce HMRC-compliant reports you can submit?
- Business use: is it designed for UK sole traders and HMRC requirements?
- Pricing: is there a genuinely free plan, or are essential features paywalled?
- Accounting integrations: can it sync to Xero, QuickBooks, FreeAgent or Sage?
Which type suits different users
Based on the factors above, here is which type of mileage tracker tends to suit different users:
- Calendar-based is best if you already use Google Calendar or Outlook for work and want to avoid GPS tracking and manual entry.
- GPS-first is best if you make many journeys, want automatic capture and do not mind battery drain or location tracking.
- Manual is best if you make few journeys and want full control over what you record.
- Spreadsheet is best if you make very few journeys and are comfortable maintaining it.
- Accounting software features are best if you already use the software and only need basic recording.
Where MileageCalendar fits
MileageCalendar is a calendar-based mileage tracker. It is particularly useful for people whose work journeys already exist as appointments in Google Calendar or Microsoft Outlook.
Instead of asking you to track journeys separately with GPS or enter them by hand, MileageCalendar reads your calendar appointments, calculates the driving distance between them, and creates draft mileage entries. You review and confirm — the app handles the rest.
For journeys that are not in your calendar, you can add them manually with postcode calculation, plan multi-stop routes, or import Google Timeline data. And when you are ready to claim, MileageCalendar exports to Xero, QuickBooks, FreeAgent or Sage.
MileageCalendar is not the best app for everyone. If you want continuous GPS tracking and do not use a calendar, a GPS-first tracker may suit you better. But if your work is built around appointments and you want to avoid battery drain and privacy concerns, calendar-based tracking is worth considering.
