DIY Car Maintenance App: Track What You Repair Yourself

Updated 2026-08-23

If you change your own oil, swap your own brake pads, or replace your own filters, your tracking problem looks different from someone who drops the car at a shop. You need a record of the parts you bought and what they cost, not a line item on someone else's invoice, and you still need a reminder for when the next job comes due.

What DIY maintenance requires you to track

A shop keeps its own paperwork. When you do the work yourself, that record has to come from you: what part number went in, how much it cost, and when you did it. Miss that step and six months later you are staring at a used oil filter trying to remember if it was a Fram or a Bosch, or digging through a shoebox of receipts trying to work out what a brake job cost you last year.

Log the job the way you did it, not the way a shop would bill it

CarCare's service history lets you record sub-tasks, cost, provider, and notes for every entry. The provider field is not shop-specific: it is a general field, so you can enter your own name or 'Self' when you did the work yourself. Add the parts and their cost in the notes so the total cost of ownership numbers on your dashboard reflect what you paid at the parts counter, not a markup you never paid at a shop.

What CarCare does not do

CarCare does not tell you how to do the repair. There are no torque specs, no part numbers, no step-by-step instructions, and no diagrams. If you need the repair procedure itself, torque values for your lug nuts or brake caliper bolts, or the correct fluid type for your engine, you still need a service manual, a forum thread for your model, or a paid repair database. CarCare is where you write down what you did after you have looked that up elsewhere, and where you get told when to do it again.

Reminders don't know who turned the wrench

The oil-change reminder uses a dual trigger: whichever comes first between a set number of months or a mileage figure. It does not care whether a shop logged the last change or you did it yourself in your driveway. Once you log the job with the mileage and date, the next due date recalculates from there. The same logic applies to tire rotations, road tax and vignette renewals, insurance renewals, and periodic technical inspections. Doing your own work does not make the schedule easier to remember. It removes the shop that would otherwise send a reminder postcard, which is why the dashboard's due-soon and overdue badges matter once you are doing the work yourself.

A DIY-friendly setup

• Add each vehicle with its make, model, and year so recall lookups and service history stay per car.
• Log every job with sub-tasks, parts cost, and 'Self' as the provider so total cost of ownership reflects what you spent on parts.
• Set the oil-change interval by months and mileage so the reminder fires on whichever comes first.
• Check the dashboard's attention banner before starting a job, since it surfaces whatever is due first on that car.
• Install CarCare as a PWA so it works as an offline-capable app if your garage does not have signal.

Multiple project cars, and what it costs

Solo is free forever for one car and does not require a card. If you keep more than one project car, a daily driver plus something in the garage, Family covers up to three cars for $39 a year. Fleet includes three cars for $45 a year, then $7.99 a year for each additional car, which fits a household running more than three vehicles. Every new account starts with a free trial of the paid features, no card required, that ends after 10 logged entries, once the account has 2 cars, or after 30 days, whichever happens first.

CarCare does not provide legal, insurance, traffic, or mechanical advice. Always confirm deadlines and requirements with your owner's manual, a qualified mechanic, or your local authority.
