Where trip auto-logging never drops a shift and service reminders fire, and where data vanishes when you switch phones. レビュー本文のスコアが高いのはRoad Trip MPG（82/100）、MileIQ（72）、Car Cave（71）です。
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.
評価点
A living developer who replies fast, no ads or subscriptions, detailed expense and mileage analytics, proven across 10+ years of real use
不満点
Data silently truncates beyond 3 years, iPad version costs extra, cross-iPhone sync broke after an update, motorcycle support is incomplete
向いている人：Drivers who want an honest expense and MPG history without ads or monthly fees
MileIQ accurately tracks mileage for tax reporting and has worked reliably for years, but an aggressive price jump from $60 to $140 a year with no new features is pushing loyal users to competitors.
評価点
Automatic trip detection, easy personal vs. business split, clean export for accountants, stable performance over multiple years
不満点
Price doubled from $60 to $140 a year with no added value, occasionally misses trips, support only responds through an AI bot, no automatic toll tracking
向いている人：Freelancers, real estate agents, and road-heavy professionals who need clean mileage logs for taxes and are okay with the price
A maintenance log for multiple vehicles with receipt photo attachments. Strong on support and long-term record storage, weak on rigid pricing and login issues.
評価点：Stores years of service history with attached receipt photos, convenient for owners of multiple vehicles
不満点：Occasional login problems, one-vehicle limit on the free tier, upgrading from personal to fleet plan jumps to $100 per month with nothing in between
向いている人：Responsible owners of multiple vehicles who want a complete service history
An automatic mileage tracker for self-employed workers and couriers with tax reporting. Runs in the background and saves time at tax time, but a persistent banner blocks GPS and there are transaction bugs.
評価点：Automatic trip tracking, tax export, bank card integration, saves real money on deductions
不満点：Banner covers navigation while driving, no undo button, duplicate trips, bank linking issues, account deletion is difficult
向いている人：Couriers, freelancers, and gig workers who need automatic mileage tracking for taxes
A solid automatic mileage tracker with years of stable operation, a clean interface, and reliable trip detection, but a 15-trip monthly free limit and $11-13 per month for full access turns many people away.
評価点：Starts automatically when you drive, stores years of history, clean tax reporting, responsive support
不満点：Hard 15-trip limit with no warning, high subscription price, sometimes fails to end a trip when stopping at a gas station, export occasionally crashes
向いている人：Drivers with a small number of business trips per month or those willing to pay for reliable auto-tracking
ZUS is an OBD2 device with an ecosystem: mileage tracking, code diagnostics, tire pressure monitoring, HUD, and a trip rewards program. The feature set is wide and impressive when stable. Weak points are unreliable code reading on some vehicles and iOS compatibility breaking after major OS updates.
評価点：Wide feature set in one device: OBD2 codes, tire pressure via add-on sensor, HUD, mileage tracking, and small trip rewards
不満点：Misses real error codes on some vehicles (Chrysler cited), features temporarily break after iOS updates, rewards program is inconsistent
向いている人：Car owners who want an all-in-one gadget for basic diagnostics and monitoring without expecting professional-grade accuracy
TripLog is a mature mileage tracker with tax-ready reports, flexible modes, and automatic monthly summaries. Works reliably in manual mode. The main problem is that the BT beacon auto-tracking misses trips inconsistently, and users only find out at the end of the month.
評価点：Flexible tracking modes, automatic monthly report, support for multiple businesses in one account
不満点：BT beacon silently skips trips, settings reset after updates and months of data are lost, annual report was removed and is now monthly only
向いている人：Self-employed workers and landlords who log mileage manually or by schedule and need clean tax exports
A mileage tracker for tax reporting with automatic trip logging and report export, but the auto-tracking is unreliable (misses up to a third of the route), CarPlay is incompatible, and support refuses refunds.
評価点：Automatic logging with no manual start, Google Maps integration, clean ad-free interface, useful for gig workers at tax time
不満点：Misses up to 50% of trips, incompatible with CarPlay, duplicates addresses with different abbreviations, support refuses refunds for broken tracking

A clean multi-vehicle maintenance log with reminders and a web version, but the free tier is heavily restricted and the paid version is locked behind a subscription instead of a one-time purchase.
不満点：Free tier limits are hidden until after you enter data, deletes a car without confirmation when adding a new one, web sync breaks for some subscribers
向いている人：Owners of 2-4 vehicles who want one clean log and are willing to pay around $2 a month
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.
評価点：Works reliably over 4-8 years, accurate real fuel consumption vs. car display, combined time-and-mileage service reminders
不満点：Record limit blocks without warning, Pro version migration breaks, data export requires a separate purchase, EV import does not work
向いている人：Owners of multiple vehicles who care about years of expense history and service intervals
An earnings and mileage aggregator for gig drivers with convenient tax reporting, but mileage tracking fails regularly, and market analytics are tied to large cities and often useless in smaller ones.
評価点：Auto-pulls earnings from multiple platforms, easy tax export, airport stats help rideshare drivers
不満点：Mileage tracking is unstable, price jumped to $108 per year, ads appeared even for paying subscribers, market insights only work in large cities
向いている人：Uber and Lyft drivers in large cities who want a single earnings and mileage dashboard
Hurdlr is a multi-tool for freelancers combining mileage, expenses, and taxes in one place. A plus for couriers and real estate agents. The downside is bank connections drop constantly and the tracker splits one trip into dozens of segments at every stop.
評価点：Combines mileage, income, and expenses in one interface, simplifies tax prep
不満点：Bank disconnects repeatedly and creates duplicate transactions, tracker chops every trip into fragments at each stoplight
向いている人：Couriers and self-employed workers who want a single mileage and expense log and can tolerate bank sync failures

評価点：Fast data entry, Dropbox export, Apple Watch support, trip categories for tax reporting
不満点：Data lost when switching phones, ads appear without notice, IRS rates are not updated, auto-tracking only works when started manually
向いている人：Freelancers who need a basic business trip log for taxes without complex features
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.
評価点：Simple fillup and service entry, cross-device sync, free core, large vehicle database, compare fuel economy with other users
不満点：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
向いている人：Budget-conscious drivers who want to track fuel economy and service history without spending money
A feature-rich fuel and expense tracker with solid analytics, but recurring sync issues, disappearing records, and aggressive plan changes without notice undermine trust.
評価点：Rich analytics, receipt photo storage, multiple vehicle support, works for Uber and Lyft drivers
不満点：Fuel entries stop saving without warning, data disappears during transfers, subscription changes without notification, support goes silent
向いている人：Gig workers with multiple vehicles who can tolerate unreliable sync in exchange for detailed analytics
CARFAX Car Care is valuable as a service history repository and recall checker, but unstable behavior after every update and unreliable record saving undermine trust in a tool where accuracy is critical.
評価点：Service history tracking for multiple vehicles, open recall notifications, ability to store receipts and avoid unnecessary service (one user example: $800 saved on transmission fluid)
不満点：After every major update the app freezes on the splash screen for weeks, new records often fail to save, odometer shows incorrect values, the same record gets duplicated eight times
向いている人：Owners of multiple vehicles who care about service history and are willing to tolerate post-update instability
An OBD2 scanner with plain-language error code explanations and severity ratings, but the subscription flow is designed so users accidentally agree to a $100-per-year charge without a clear warning.
評価点：Reads error codes and explains them in plain language, shows estimated repair costs, helps when buying a used car, live engine data
不満点：Hidden $99-106 per year auto-subscription, children can accidentally enable paid access, difficult cancellation, 2FA required on every connection, mileage prediction outputs random numbers
向いている人：Car owners who read the fine print carefully and want to understand error codes without going to a shop
Carly is an OBD2 scanner with deep BMW support: coding, full module diagnostics, and solid code descriptions. Works well for BMW owners. For other brands the feature set is much thinner, and an auto-renewing subscription you can only cancel through support generates consistent frustration.
評価点：For BMW: deep coding, all-module support, clear error descriptions, responsive support for hardware problems
不満点：Subscription auto-renews without a reminder, can only be cancelled through support, limited functionality for non-BMW vehicles
向いている人：BMW owners who want to diagnose and code their car themselves without going to a dealer

評価点：Vehicle inspections with photos, trip tracking, digital forms replacing paperwork
不満点：Crashes when switching from WiFi to cellular, no Face ID or Touch ID, cannot upload saved photos, crashes when opening the parts catalog, support does not respond
向いている人：Corporate fleet drivers whose company uses Fleetio as its fleet management platform
Motus is a corporate mileage reimbursement tracker. When running in Power Supply Only mode, tracking is stable. The main problem is that the app automatically logs users out without notice, losing weeks of mileage data.
A simple multi-vehicle maintenance log with photos and reminders, but one update reset dates for thousands of users and trust in data integrity is damaged.
評価点：Free core version, multiple vehicle support, photos attached to records, complete service history in one place
不満点：Mass date reset to 01/01/1900 after an update with no warning, crashes when opening settings, photos disappear, no cloud backup in the free version
向いている人：Anyone who wants a simple free log and accepts the risk of data loss on major updates
A multi-vehicle maintenance log with a clean interface but catastrophically unreliable cloud backup: data regularly disappears after updates and device changes.
評価点：Easy to add multiple vehicles, export in multiple formats, intuitive interface
不満点：Cloud sync wipes data after updates, no custom service categories, ads cannot be turned off, adding a fourth vehicle fails
向いている人：Anyone managing multiple vehicles who accepts the risk of losing service history on updates
Once a solid mileage and expense tracker, but development has been abandoned: Google Drive backup has been broken since early 2025, the app crashes on iOS 18, and paid subscriptions cannot be restored.
評価点：One-time payment instead of a subscription, multiple vehicle support, truck drivers praise the simplicity
不満点：Google Drive backup broken since January 2025, crashes on iOS 18, developer support unavailable, data lost when switching phones

評価点：Free, simple interface, built-in expense tracking, convenient for gig workers when it works
不満点：Mileage disappears after 4-8 hours of driving with no warning, auto-tracking often stops on its own, no DoorDash Crimson card integration, aggressive notifications that cannot be disabled without losing functionality
向いている人：Gig workers with short shifts who check the app regularly. Long shifts without monitoring risk a full data wipe.
A simple fillup tracker with flexible unit support, but without reliable cloud backup data is regularly lost when upgrading a phone, and the MPG formula produces errors.
評価点：Supports mixed units (odometer in km, fuel in gallons), clean interface, no ads in the paid version
不満点：Data lost when switching devices even in the Pro version, MPG formula gives incorrect values, white text on white input field makes the app unusable
向いている人：Owners of imported vehicles with non-standard units who are willing to maintain manual backups
A directory of truck and RV fuel stations for long US road trips, useful for Flying J and Loves fans, but the database has not been updated in a long time and misses about half of the real chains.
評価点：Finds fuel stops with RV lanes and propane where Google Maps falls short, works well alongside other road trip apps
不満点：No fuel prices, missing Kwik Trip, BP, Exxon, Sheetz, and Buc-ee's, filters do not affect the map, no user-submitted locations
向いている人：RV travelers in the US who stick to Flying J and Loves and know about the database limitations
A mileage tracker with basic features but aggressive monetization: the free version is nearly fully locked, and entering a card triggers attempted unauthorized charges.
評価点：Trip copy feature for recurring routes, fast support response on real bug reports
不満点：Attempted unauthorized $39.95 charge for a music add-on during card verification, GPS and export are paywalled, the copy feature is broken and copies the wrong trip, data disappears

A free background mileage tracker for tax deductions, but over the past year it regularly loses trips, crashes on export, and covers the interface with intrusive ads.
評価点：Runs in the background with no manual start, distinguishes personal and business trips, genuinely free
不満点：Drops entire weeks of trips, CSV export crashes, ads block the category switcher, no backup so history is gone when you change phones
向いている人：Anyone willing to accept instability in exchange for a zero cost and who does not store data beyond a season
A Saudi Arabia aggregator for mobile auto service and car washes. Convenient in theory, but in practice coordination between operators is chaotic, repairs stretch from 4 days to 3 months, and refunds for cancelled services are refused.
評価点：Easy online booking, mobile mechanic service at your location, photo documentation of work at some shops
不満点：Different operators give contradictory information, repairs drag from 4 days to 3 months, no refunds for purchased packages when cancelled, PPF and coatings were damaged during washing
向いている人：Saudi Arabia users with small non-urgent tasks like a car wash or routine service who can accept delays
A subscription mobile tire installation service, not a maintenance tracker. Since mid-2025 the company has stopped responding to users while continuing to charge subscriptions.
評価点：When operational: fast on-site tire installation at the customer's location, good support
不満点：Company has effectively shut down: tire technicians do not show up, emergency service does not answer, subscription cannot be cancelled and charges keep coming
