Help with Lugnut

On the old device, open Settings → Backup & Import → Back Up Everything… and save the file to iCloud Drive, Files or your Mac. On the new device, install Lugnut and choose Restore From Backup… in the same place. One backup file holds every vehicle, record, photo and document.

Yes, with Lugnut Pro. Settings → Backup & Import → Import From Another App… reads exports from Fuelly, Drivvo, Fuelio, Simply Auto, aCar, Road Trip MPG, LubeLogger or a spreadsheet, and service history from a PDF or photo, such as a CARFAX report or a dealer printout.

Lugnut reads receipts on your device and shows everything for you to check before saving. For the best result:

• Photograph the page flat, in good light, filling the frame.
• Add every page of a multi-page invoice to the same service. The totals are usually on the last page.
• Fix any amount or date on the review screen, or tap Read Details from Receipt to read the attached pages again.

If an invoice keeps coming out wrong, send it to the developer from Contact the Developer (blur out personal details first if you like). Real examples help improve the reader.

In the service's Cost section, turn on Covered by Warranty and enter the deductible, if you paid one. The work stays in your history, and only the deductible counts toward your spending. Dealer invoices billed entirely to warranty or a recall turn this on automatically.

Lugnut works with Bluetooth LE adapters of the ELM327 type, such as the Vgate iCar Pro BLE or Veepeak BLE. Adapters that use only classic Bluetooth can't connect to an iPhone. To see how it works without an adapter, open a vehicle's Diagnostics page and tap Try a Demo Check.

Lugnut only reads data. It doesn't clear codes or change settings. Some adapters drain the battery if left plugged in; check the maker's instructions.

Recalls come from Transport Canada for Canada and from NHTSA for the United States, listed by make, model and year. Check that Settings → Region is set to your country and that the vehicle's make, model and year are filled in. Recall lists aren't available for other countries yet. A dealer can confirm with your VIN whether a recall applies to your vehicle.

Check that notifications are allowed for Lugnut in your device's Settings, and that Focus or Do Not Disturb isn't hiding them. Reminders are based on the date and odometer you enter, so keeping the odometer up to date keeps them accurate.

The free version keeps one vehicle with its service records, receipt scanning, reminders, recalls, CSV export and backups. Lugnut Pro adds more vehicles, OBD diagnostics, seasonal tire advice, warranty tracking, the service history PDF, and imports from other apps and CARFAX.

New subscribers get one month free. You'll get a reminder a few days before the trial ends. If you don't cancel at least 24 hours before it ends, the subscription renews at the price shown in the App Store.

In Lugnut, open Settings → Subscription → Cancel or Change Subscription. You can also manage it in your Apple Account settings under Subscriptions. Cancel at least 24 hours before the current period ends to avoid the next charge. If Pro ends, your records stay and can still be viewed and exported.

Open Settings → Subscription and tap Restore Purchases, signed in with the same Apple Account. Lugnut Pro works with Family Sharing, so up to five other family members in your Apple family group can use it too.

Purchases are handled by Apple, so refunds are requested from Apple at reportaproblem.apple.com.
