Fillr support
& FAQ.

Open Fillr and add a vehicle from the vehicles screen. You can give it a name and the basic details Fillr needs to track fuel, costs and reminders.

Free users can track one vehicle. Multiple vehicles are supported with Fillr Pro.

No. Fillr does not require an account, registration, or sign-in. There is no WolfMark login. Just install the app and start using it.

Fillr is a native iOS app, built for iPhone. There is no Android version.

From the vehicle screen, add a fill-up and enter the details you know - litres, price per litre, total cost, and the odometer reading. Fillr will calculate the remaining values for you where possible.

Logging the odometer at each fill-up is what makes the MPG and cost calculations accurate over time.

Fillr calculates MPG and fuel economy from your fill-up history - the distance covered between fill-ups and the fuel used. The more fill-ups you log, the better the trend you get over time.

Yes. Fillr lets you log both full and partial fill-ups, and handles the calculations so your MPG figures stay accurate.

You can add service visits, repairs and routine maintenance against each vehicle, with the date, cost and any notes you want to keep. Fillr stores them alongside your fuel records so you can see total running costs.

Fillr lets you set renewal dates for MOT, road tax and insurance. Reminders are generated locally on your device - there is no external service involved.

You can grant or revoke notification permission at any time in iOS Settings → Notifications → Fillr.

No. Fillr does not currently look up MOT, tax or insurance dates from any external service. You enter the renewal dates yourself.

Fillr Pro is a one-time in-app purchase that unlocks multiple vehicle support and the enhanced/Pro features currently available in the app.

There are no subscriptions. You buy it once and keep it.

If you've previously bought Fillr Pro - for example after reinstalling or switching device - use the Restore Purchases option in Fillr's settings. As long as you're signed into the App Store with the Apple ID you used to buy it, Pro will be restored.

WolfMark cannot restore Pro for you directly because all purchases are handled by Apple.

No. Fillr Pro is a one-time in-app purchase, not a subscription.

All of your vehicles, fill-ups, service records and reminders are stored locally on your device using Apple's SwiftData framework. WolfMark does not receive or hold any of this data.

Full details are in the Fillr Privacy Policy.

Fillr does not sync your data to any WolfMark cloud service. There is no cloud sync in v1.

If you have iCloud Backup enabled on your device, Apple may include Fillr's local data in your device backup. That is controlled by your iOS settings and is handled entirely by Apple.

Because Fillr's data is stored on your device, deleting the app removes the local app data. If you have iCloud or device backups that include Fillr, that data may still be recoverable through those backups, depending on your iOS settings.

If you're switching device or reinstalling and want to keep your records, restore from a backup before reinstalling - or use any available export feature first.

No. Fillr does not show adverts and does not include tracking or analytics SDKs. See the Fillr Privacy Policy for the full details.

Fillr 1.11 includes regional profiles for the United Kingdom, Ireland, United States, Canada and Australia. You can change region at any time in Settings.

The default region is United Kingdom, so UK users keep the same experience they had before unless they change it.

Region controls currency, distance units, fuel volume units, fuel price formatting (such as p/L or ¢/gal), fuel economy units (MPG Imperial, MPG US or L/100 km) and the renewal labels and reminder notification wording used in the app.

Entries you saved under a previous region remain visible with neutral wording rather than being shown under incorrect regional labels.

Fillr uses the currency that matches the region you choose in Settings. The default region is United Kingdom, which uses pounds sterling (£). Switching region updates the currency and fuel price formatting throughout the app.

No. If you are in the UK and have not changed region, MOT, Road tax and Insurance labels and flows remain unchanged. Your existing stored data and reminders are preserved.

Use the WolfMark contact page with the Fillr topic preselected. Include as much detail as you can - what you were trying to do, what happened, and your device and iOS version if relevant.
