The driver card for sim racers
A driver card with career stats, the race schedule, a journal of every race and leaderboards, on iOS and Android. Low Fuel Motorsport and Le Mans Ultimate accounts link into a single profile, and every race from a linked account appears there, with a public link for sharing the card.
Profile, Schedule, Journal and Ranks are the four tabs, and the public share page opens from the card. Every screen below fills in from the linked accounts, with nothing to type by hand. The tag on each row names the source.
gridcard.site/c/<handle>, open in any browser, with career totals and pinned milestones.Free covers the driver card, the share page, sim linking, schedules, per-sim stats, the leaderboard top ten, earned frames, milestones and part of the journal. PRO adds the rest.
Races arrive in two ways. Low Fuel Motorsport is linked with the LFM handle in the app and covers six sims. Le Mans Ultimate has no public API, so the free Windows companion reads each race from the PC and sends it to the phone. Either one works on its own, and both can be linked at the same time.
One Low Fuel Motorsport link covers six sims.
Results, ratings, the race calendar and the full championship standings arrive through one account link for all 6 sims covered by LFM: Assetto Corsa, AC Evo, Competizione, Automobilista 2, RaceRoom and LMU.
Linked in the app with the LFM handle.

Finish a race on the PC, see it on the phone seconds later.
Low Fuel Motorsport also lists LMU races. The companion goes further: it reads each LMU result from disk and sends it to the mobile app, with lap times, sectors, position and tire wear. It also reads the current Le Mans Ultimate Driver and Safety rating and shows it on the driver card.

Low Fuel Motorsport covers LMU as one of its six sims. The companion reads LMU from the PC and has more detail. The table lists the differences.

An LMU race on Low Fuel Motorsport shows up through both links. The companion adds the lap times, the sectors and the full field, and it covers every LMU race on the PC, whether it ran on LFM or not.
Paste a card link into a chat and the full card unfolds under the message. Discord, iMessage and other chat apps show the card image, the name and the career totals.
Card theme, the earned tier frame and the PRO stamp carry over from the app.
A browser source in OBS shows the live LMU rank, and the result of each finished race. LMU only, and English only. One link per streamer, issued on request.
GridCard is a small project that I build alone in my free time. I work full-time as a senior software engineer, which means this app is NOT vibe-coded. I used AI to increase the development speed, but I understand what I am doing. I have worked on many mobile projects in my professional career and still do today.

Every month I pay for the servers, the database and the business address in the Impressum. The developer accounts for Apple and Google cost money too. And there are many hours of work in this app, most of them evenings and weekends.
I know there are many subscriptions today, so I tried to keep the price low. One month of PRO costs about the same or even less than a single coffee, and an entire year is about the price of one lunch. The app shows the exact price in your currency.
I appreciate every user, free or PRO. And a big thank you to everyone who thinks the app is worth paying for.
The free app covers the driver card, the public share page at gridcard.site/c/<handle>, sim linking, schedules, per-sim stats, the full Low Fuel Motorsport championship standings of every series and division, the leaderboard top ten, earned card frames, milestones, race-finish notifications and a journal with the latest race and the weekly streak. PRO adds the following:
