  1. Fuelly: MPG & Service Tracker

    Rank 17. Review score: 55 out of 100. App Store rating: 4.7★ · 29,171 ratings

    A ten-year veteran for tracking fuel and service work, functional and free, but the iOS app lags well behind Android in features and has not been updated in over a year.

    Praised: Simple fillup and service entry, cross-device sync, free core, large vehicle database, compare fuel economy with other users

    Complaints: iOS version has fewer stats and charts than Android, no updates in over a year, periodically logs you out, stations disappear from the database, cannot insert a missed fillup without a cascading recalculation

    Best for: Budget-conscious drivers who want to track fuel economy and service history without spending money

  2. Road Trip MPG

    Rank 1. Review score: 82 out of 100. App Store rating: 4.9★ · 624 ratings

    One of the best fuel and expense trackers on iOS: has been around since 2009, a responsive developer who answers email directly, no ads, no subscriptions. Downsides are data getting cut off past 3 years and iOS-only.

    Praised: A living developer who replies fast, no ads or subscriptions, detailed expense and mileage analytics, proven across 10+ years of real use

    Complaints: Data silently truncates beyond 3 years, iPad version costs extra, cross-iPhone sync broke after an update, motorcycle support is incomplete

    Best for: Drivers who want an honest expense and MPG history without ads or monthly fees

  3. Pure Gas

    Rank 15. Review score: 58 out of 100. App Store rating: 4.6★ · 2,897 ratings

    The only widely available ethanol-free gas station finder in the US, useful for classics and motorcycles, but the database goes stale and the developer is nearly unreachable.

    Praised: Finds ethanol-free gas where you cannot find it otherwise, simple to use, volunteer project with no monetization

    Complaints: Map listings do not stay current and some stations have closed, no octane rating filter, search is limited to a 30-40 mile radius, data entry is broken after an update (cannot enter decimals)

    Best for: Owners of classic cars, motorcycles, and aircraft who need gas without ethanol

  4. Fuel MPG Calculator

    Rank 8. Review score: 62 out of 100. App Store rating: 4.6★ · 352 ratings

    A fuel consumption tracker with fillup and service history. The core is reliable, but a version 3.0 update wiped years of data for many users.

    Praised: Free app with no ads, data stored in the phone's backup, developer personally helped users recover corrupted records

    Complaints: The 3.0 update broke measurement units and destroyed 4-6 years of data for many users

    Best for: Drivers who keep a long-term fillup and fuel consumption log

  5. Fuel Monitor Pro

    Rank 12. Review score: 59 out of 100. App Store rating: 4.4★ · 814 ratings

    A mature multi-vehicle expense and fuel tracker with service interval tracking, but the monetization model changed and users now hit record limits or lose access to old data.

    Praised: Works reliably over 4-8 years, accurate real fuel consumption vs. car display, combined time-and-mileage service reminders

    Complaints: Record limit blocks without warning, Pro version migration breaks, data export requires a separate purchase, EV import does not work

    Best for: Owners of multiple vehicles who care about years of expense history and service intervals
