WolfMark Ltd is an independent UK software studio building practical tools, apps, and systems for streamers, creators, and everyday users. The company is registered in England and Wales (company no. 17176391).

The work spans Streamer.bot-powered tools like AlphaStats, iOS apps like Fillr, and longer-term projects like Howlies. Everything is built with the same approach: software that does something useful, does it well, and respects the person using it.

Yes. WolfMark Ltd is a registered limited company in the United Kingdom. WolfMark.co.uk is the studio site for the company — products, projects, and everything built under the WolfMark name.

Mark runs WolfMark Ltd — design, build, and support across AlphaStats, Fillr, and the rest of the portfolio. It's a solo studio today, backed by a registered UK company.

You can learn more on the About page.

WolfMark.co.uk is the studio site — this site. It explains what WolfMark is, what's being built, and where everything fits.

WolfMark.tools is the storefront for streamer tools and downloads, including AlphaStats. Fillr is on the Apple App Store. Think of .co.uk as the company site, and .tools as the download hub for Streamer.bot tools.

It depends on the product. Streamer tools like AlphaStats are free from WolfMark.tools. Fillr is on the Apple App Store for iPhone. See each product page here for the right link.

The core of every WolfMark product is free to get started with. AlphaStats is completely free. Fillr is free to download with a one-time optional Pro upgrade (£2.99) for unlimited vehicles.

There are no subscriptions. If a paid option exists, it's a one-time purchase - you own it.

AlphaStats - a free Streamer.bot-powered stats system for Marbles on Stream. Live now on WolfMark.tools.

Fillr - an iPhone app for vehicle and fuel cost tracking. Now live on the App Store at v1.11.

More products are in development. See the full picture on the Roadmap.

Yes. Fillr is now live on the App Store at version 1.11. Download Fillr on the App Store, or see the Fillr page for more details.

Fillr 1.11 includes regional profiles for the United Kingdom, Ireland, United States, Canada and Australia. Region controls currency, distance, fuel volume, fuel price formatting, fuel economy units (MPG Imperial, MPG US or L/100 km) and renewal labels and reminder wording.

UK defaults are preserved for UK users — MOT, Road tax, Insurance, pounds sterling and miles remain the default unless you choose a different region in Settings.

Yes - Fillr is currently built for iPhone. There are no plans for Android at this time.

No. Fillr is designed to work entirely on-device. No account is required, no internet connection is needed, and your data stays on your device.

Fillr Pro (£2.99, one-time) adds unlimited vehicle tracking. The free version covers everything for one vehicle - full fuel tracking, MPG, costs, reminders, and reports. Pro is for anyone who needs to track more than one vehicle.

It's a one-time in-app purchase. No subscription, no recurring charge - ever.

AlphaStats is a free Streamer.bot-powered stats system built specifically for Marbles on Stream streamers. It reads race and Battle Royale results from CSV files, tracks everything automatically, and outputs live stats to OBS overlays and chat responses.

It runs entirely inside Streamer.bot - no separate app needed.

Yes. AlphaStats runs as a set of actions and triggers inside Streamer.bot. You'll need Streamer.bot installed and connected to your Twitch account before setting up AlphaStats.

AlphaStats is available free from wolfmark.tools/products/alphastats. Setup instructions are included with the download.

Yes, completely free. The full AlphaStats base system - race tracking, BR tracking, leaderboards, OBS outputs, chat responses - costs nothing. A planned AlphaStats+ bundle will offer optional premium add-ons in the future, but the core will always be free.

WolfMark streams live on Twitch at twitch.tv/wolfmark. Streams run Monday to Friday, 12 noon–4pm EST, with occasional Saturday streams.

Marbles on Stream is the main content - community races and Battle Royales with AlphaStats tracking live season standings. Beyond that: community gaming sessions, and occasional coding streams where WolfMark tools and apps are built live.

Yes - join the WolfMark Discord at discord.gg/9MXsUANmkf. It's where the community hangs out between streams, race results get discussed, and WolfMark updates land first.

Use the contact form and select "Product support" - or post in the relevant channel on the Discord. Include as much detail as possible: what you were doing, what happened, and what you expected to happen.

Potentially - get in touch via the contact form and select "Collaboration / creator enquiry". Describe what you have in mind and we'll take it from there.
