Your car's history lives in a glovebox full of receipts
Somewhere between the oil change you think you got last spring and the registration renewal you'll remember when the ticket arrives, most households lose the plot on their cars. The service history is a stack of faded receipts, the tire size is something you squint at in the parts-store aisle, and the maintenance schedule is a vibe.
Car maintenance apps exist to fix that, and several of them are genuinely good. Honest rundown first — you should use something, even if it's not us.
Then we'll talk about what none of them cover, because keeping a car on the road takes more than a service log.
The best car maintenance apps, honestly ranked
-
CARFAX Car Care — best free automatic optionFree, and it does the one thing no manual logger can: pull in service history automatically from CARFAX's network of reporting shops and dealers, then layer on maintenance reminders and open-recall alerts for your VIN. Tens of millions of drivers use it. The catch is the flip side of the magic — it only sees work done at shops that report to CARFAX (your driveway oil change doesn't exist), it's US-centric, and your vehicle data feeds the CARFAX ecosystem.
-
Drivvo — best full expense pictureThe most complete manual tracker: fuel, services, repairs, insurance, taxes, even income if you drive for work, with analytics that show what each vehicle actually costs you per month and per mile. Free for personal use, with a Pro tier around $30/year. Everything is manual entry, so it rewards the meticulous — and quietly punishes everyone else.
-
Simply Auto — best for shared family carsUnlimited fill-ups, services, and expenses on the free tier, receipt capture, and sync across devices so both drivers see the same log — plus a GPS mileage tracker that makes it the pick if you deduct or expense your miles. Premium runs about $10/year. The interface is more spreadsheet than showroom, but it's the strongest "one log, whole household" option.
-
Fuelly — best for fuel economy obsessivesStarted as an MPG tracker and it still shows: log every fill-up and Fuelly tells you your real-world fuel economy, then benchmarks it against thousands of identical vehicles in its community. Free with ads, about $20/year without. Maintenance logging exists but it's clearly the side dish.
-
AUTOsist — best for serious service recordsBuilt like a fleet tool that happens to have a personal tier: scan a repair receipt and it becomes a searchable digital service record, stored offline and exportable when you sell the car. Free for personal use; the paid tiers are aimed at small business fleets. If your goal is a bulletproof service history binder, this is it.
-
Fuelio — best free no-account optionFree including its pro features, no account required, and your data stays on your device with optional backups to your own Google Drive or Dropbox. Tracks fill-ups, services, and costs with calendar and mileage-based reminders. If your dealbreaker is handing vehicle data to anyone at all, this is the privacy pick.
Bottom line: if you want zero effort, CARFAX Car Care. If you want the full cost picture, Drivvo. If two drivers share the cars, Simply Auto. If you're chasing MPG, Fuelly. All of them beat the receipt stack in the glovebox.
Here's what a service log doesn't know
Every app above answers one question: what work has this car had, and when is the next service due? Important question. But think about what actually goes wrong with cars in a normal household year:
-
The registration renewalThe state doesn't care about your oil change interval. Registration, emissions, inspection — the deadlines that come with late fees and tickets live on a sticker and a postcard you recycled.
-
The insurance card and the titleWhere's the current insurance card? Which drawer is the title in? Who's the lienholder? The day you're asked is never a calm day — it's a fender-bender, a DMV counter, or a sale.
-
The parts-counter questionsTire size, wiper length, oil weight, battery group. None of it is in your service log, all of it is needed standing in an aisle at the parts store — usually while you're guessing between two wiper blades that differ by an inch.
-
The other driverMost maintenance apps assume one meticulous owner. Real households have two drivers, a teen with a hand-me-down sedan, and nobody sure whether the truck's rotation happened before or after the road trip.
-
Everything that isn't the carThe warranty on the new tires. The gift card from the detailing place. The AAA membership renewal. Your household doesn't leak money one category at a time, and a car app can't see any of the rest — we wrote about the same blind spot in subscription trackers.
A maintenance app watches the odometer. Owning cars is a paperwork problem wearing a mechanical disguise.
The Glovebox: every car, the whole picture
Squirreld approaches it from the household side. The Glovebox is one of eleven categories in your family's command center, and it's built for the questions above, not just the service log:
-
Punch in the VIN, get the carVIN decode fills in the vehicle details, and every car in the household gets its own record — the daily driver, the truck, the teen's sedan.
-
The paperwork, findablePlates, insurance, and where the title lives — stored with the car, not in three drawers, and shareable with everyone in your household.
-
The parts-counter cheat sheetTire sizes and specs on your phone, so the auto-parts aisle stops being a memory test.
-
Reminders for the deadlines that biteRegistration renewals and oil changes nudge you before they're due — the same reminder engine that watches your warranties, memberships, and pet vaccines.
And because the Glovebox sits next to your warranties, gift cards, and the rest, the tire warranty and the AAA renewal live in the same place as the car they belong to. If you want the full how-to, we've written a guide to keeping a car maintenance log.
Security-wise it's the same foundation as everything in Squirreld: encrypted with AWS KMS, no bank login required, and your data isn't the product.
The honest recommendation
If all you want is a service log, CARFAX Car Care costs nothing and Drivvo tracks everything — pick one today and your future self will thank you.
But if the real problem is the household around the cars — the registration you forget, the title you can't find, the tire size you re-Google every fall, and the two drivers who each think the other one logged the oil change — that's what the Glovebox was built for. The odometer is easy. It's the paperwork that gets you.
Squirreld is built by a dad in Colorado who got tired of losing money to junk drawers. Questions? We actually answer them.
Every car in the household — VIN, plates, insurance, tire sizes, and the reminders that keep them all legal and running.
