Car maintenance log for iPhone
Wrenchy: Car Service Log
Wrenchy is an iPhone app for keeping your car's service history: every oil change, tire rotation and repair, with the date, mileage and cost. It reminds you when each service is due by date or mileage, works for as many vehicles as you own, and keeps everything on your phone with no account.
What's the easiest way to keep track of car maintenance?
It depends on how your car gets serviced. If one dealer or a chain shop does all your work, an app that pulls records from a shop network, such as CARFAX Car Care, fills in a lot automatically and is free. If you do some work yourself, use an independent mechanic, or want to set your own intervals, a log you fill in yourself is more complete. Wrenchy is that kind of log: you add each service in a few taps, it tells you what is due next, and the records belong to you, with no account to lose access to. A paper logbook works too, but it can't remind you.
What Wrenchy does
-
Log any service in seconds
Oil changes, tire rotations, brake pads, filters, inspections, or anything else. Pick the service, the date and the mileage; cost and notes are optional.
-
Reminders by date or mileage
Every service has its own interval. Wrenchy reminds you when it is due by months or miles, whichever comes first.
-
Full history for every car
Each vehicle keeps its own odometer and service history, so you can see what was done, when, and at what mileage.
-
Plain-English service guides
Tap any service to see what it is, why it matters, and whether it is a do-it-yourself job or one for a shop.
-
Glovebox documents
Insurance, registration, inspection and warranty, with photos and a reminder before each one expires.
-
Fuel log
Log fill-ups to see fuel spend, cost per 100 miles, and real-world efficiency over the last 12 months.
-
Recall check (US)
Wrenchy checks NHTSA's public recall list for your car's make, model and year and shows any open safety recalls.
-
Export to CSV
Send your whole log to a spreadsheet at any time, for a backup or to show a buyer when you sell the car.

Who it's for
- Anyone with a car, whether it's one daily driver or several in the driveway

- Sellers who want proof of maintenance when the car goes up for sale
Your records, on your phone
Wrenchy has no account and no cloud copy of your log. Vehicles, services, costs, notes and photos are stored on your iPhone. The app sends usage and crash reports, tied to a random ID rather than your name or email, so we can fix problems. It never sends the contents of your log. The privacy policy lists exactly what leaves the phone.

Questions
Do I need an account to use Wrenchy?
No. There is no sign-up and no login. Your vehicles and service records are stored on your iPhone, and the subscription is tied to your Apple ID through the App Store.
What happens to my records if I delete the app or lose my phone?
Your records are stored in the app on your phone, so deleting the app deletes them. They are included in your iPhone's iCloud or computer backup, so a new phone restored from that backup has them. You can also export the whole log to a CSV file from Settings and keep it in Files, iCloud Drive or email.
Can I track more than one car?
Yes. One subscription covers every vehicle you add, each with its own odometer, history and reminders.
How does Wrenchy know when a service is due?
Each service has an interval in miles (or kilometres) and in months. Wrenchy counts from the last time you logged it and reminds you at whichever comes first. You can change any interval to match your owner's manual.
Is Wrenchy on Android?
Not yet. Wrenchy runs on iPhone (and iPad) with iOS 16.4 or later.
How much does Wrenchy cost?
Wrenchy is a subscription. As of October 2026 in the US it is $39.99 a year, $5.99 a month, $3.99 a week. See the pricing page.
