BillFighters, among friends
The trailer starts here.
Episodes under a minute, no voice-over, shot inside the app. Episode 1, “The bill”, plays on the Who pays the bill? page; the rest of the series is on our social channels.
Among friends, who owes what? BillFighters splits the group’s expenses, works out who owes what to whom, lets a game decide who pays the bill, and tracks the pot for outings and trips.
Video description
Series trailer. Music, no voice-over. Shot by shot, with the main on-screen text:
- Four receipts (58.00 €, 96.80 €, 124.00 €, 86.40 €) above four friends: Léa, Thomas, Sofia and Noah. Caption: “Among friends, who owes what?”
- Léa’s phone, the app’s home screen: “Hi, Léa Martin — Ready for a new draw?”, then “My Groups”: “Flatshare 2026” (4 members · 21 draws) and “Lisbon weekend” (3 members · 13 draws). Caption: “BillFighters splits your group’s expenses.”
- “New expense” screen: “Weekly groceries”, “Amount” 86.40 €, “Paid by” Léa Martin, “Participants” Léa Martin, Thomas, Sofia and Noah, “Split mode” “Equal”, “21.60 € / person (4 participants)”. Then Thomas’s, Sofia’s and Noah’s locked phones, 20:45, get the same BillFighters notification: “New expense — Léa Martin added ‘Weekly groceries’ (86.40 EUR)”. Caption: “Léa adds an expense. The whole group is notified.”
- Léa’s phone, “Balance per member”: Léa Martin +13.27 €, Noah −38.14 €, Sofia −10.83 €, Thomas +35.70 €; “Active debts”: “2.44 € — Noah owes you — Pending — It’s paid”. Bubble: “3 transfer(s)”. Caption: “The app works out who owes what to whom.”
- “FLASH DRAW”: the wheel with the four names (Léa, Thomas, Sofia, Noah) slows down and stops on Thomas. Verdict card: “Thomas — IT’S YOU WHO PAYS! — 48.00 € — The lightning chose you. Resistance is futile.” Caption: “The restaurant bill? A game decides who pays.”
- Three phones in the middle of a game, each with its “LIVE” badge: LAST STAND, RUSH and GÂCHETTE. Caption: “8 games, live on every phone.”
- “Chalet weekend” event: “Pot collected” €240 of €360, “Remaining” €120. Thomas’s payment comes in (“Thomas · For Thomas”, €120) and the pot reaches €360 of €360, 100%, “Pot complete”. “Recorded payments”: 2, with Léa’s (“Léa Martin · For Léa Martin, Sofia”, €240). Caption: “Outings and trips: everyone sees what they owe.”
- End card: “BillFighters — May the best not pay! — Free · iOS and Android”.

Frequently asked questions
Yes, and free forever. The free plan covers the essentials: up to 10 groups, unlimited draws, automatic settling up, strategy cards, 3 currencies and all 3 languages (FR / EN / AR). Premium unlocks the rest: zero ads, 25 groups, 54 currencies, smart OCR, PDF export, advanced charts, more cards and 5 photos per expense instead of 3.
Pick a mode among the 8 games included: 5 animated draws (Flash Draw, Sprint, Swimming, Laser, Zombie) and 3 live multiplayer mini-games (LAST STAND, RUSH, GÂCHETTE). Everyone plays in real time and the animation stays in sync. Depending on the mode, either the result designates the payer directly (Flash Draw) or the group votes on the rule — winner pays or loser pays. You can also play cards before the draw to sway who gets picked as payer. Two express modes come on top: Finger Chooser and the team match inside events.
No. It is not gambling: nobody bets and no money goes through the app. The random draw, or the mini-game, only decides who pays the bill among friends.
No. You can add guests: they take part in the draws and appear in the balances without signing up. If a guest later creates an account, they can take over their spot and history at any time through the "Were you already a member?" link under the member list — and during their first 7 days in the group, the app even offers it automatically.
Reading happens 100 % on your device: Google ML Kit on Android, Apple Vision on iOS — the photo never leaves your phone. On supported devices the scanner detects the receipt edges and straightens it before reading, which helps a lot with a crumpled or angled receipt. Latin-script receipts (French, English…) are recognised well; Arabic is not recognised on Android. If reading fails, you simply type the amount in. Smart OCR is part of the Premium benefits.
Secure authentication, data encrypted in transit and at rest, hosting on European servers (Supabase), GDPR compliance. Deleting your account is something you do yourself from the app; what is erased and what remains is detailed in the privacy policy. On GDPR portability, the built-in export currently covers your Events data: for a copy of everything else, write to us and we will send it over.
Create an event (dinner, trip, cinema, football, drinks, group gift) and invite your friends — even outside the group, through a revocable public link. The shared pot is tracked in real time and the FIFO waitlist automatically promotes people when a spot frees up. Push notification included.
Yes, in one tap from your App Store or Google Play account settings. No penalty, no questions. You keep access until the end of the period you already paid for.
The app is translated into French, English and Arabic. It downloads from the App Store and Google Play — country-by-country availability depends on the stores, so check yours. On the money side: 3 currencies on the free plan, 54 currencies with Premium plus automatic conversion.
