How to build a mileage tracker app for iOS

What a mileage tracker app needs

• Trip logging, either manual start and stop or automatic detection
• A map of the route and the distance for each trip
• Business or personal classification, with a quick swipe to set it
• A per-mile rate the user can set, and a running deduction total
• Categories or clients to group trips
• Reports you can filter by date and export as CSV or PDF
• An odometer or start and end address per trip

The product is built around automatic tracking and clean export. Manual logging is a fallback; the reason people switch from a spreadsheet is that the app captures drives on its own and hands them a report.

How to build it with AppFlight

Describe it in plain English, for example: "A mileage tracker that detects when I am driving and logs the trip with a route map and distance in the background. Let me swipe each trip to mark it business or personal, set a per-mile rate, and group trips by client. Show a running deduction total, and let me filter by date and export a report as PDF or CSV." AppFlight plans the screens, generates native SwiftUI that uses Core Location for drive detection and MapKit for the route, and launches it in a live simulator so you can log and classify a trip. You iterate in plain language, for example adding monthly summaries or multiple vehicles. Background location use needs a clear purpose string and the right permission, which AppFlight sets up as part of the build.

Monetization for a mileage tracker app

The reliable model is a free manual log with a paid upgrade. Free users log trips by hand and see totals; the subscription unlocks automatic GPS tracking, unlimited trips, multiple vehicles or clients, and report export. Add a RevenueCat paywall to manage subscriptions, and use Superwall to test paywall designs without shipping an update. This is a category where the value is concrete, the deduction the app helps capture, so an annual plan timed near tax season tends to convert well.

Shipping it to the App Store

When the app is ready, AppFlight signs the build, uploads to TestFlight so you can test background tracking on a real drive, then submits to the App Store with metadata and screenshots from the simulator. If Apple rejects the build, AppFlight reads the reason, works on the fix, and resubmits. Background location is reviewed closely, so explain why you need it in the permission prompt and your listing, include a real privacy policy, and present mileage totals as records rather than tax advice. Apple reviews every app, so a submission is not the same as an approval, but the whole pipeline runs without you opening Xcode.
