No more folded papers and cheating cousins: set up your party in the app, run the draw, and everyone secretly discovers who they're gifting. Couples never draw each other, gifts are tracked with photos, and nobody can get the wrong person.

Couples and family members never draw each other — exclusions are mutual, set in two taps before the draw.

Game rules

Who wins? Who loses? Who pays?

Everything is transparent. You always stay in control.

Tracked or not

Each draw can be tracked in debt balancing or just for fun. You decide!

Replay without limits

Launch as many draws as you want. Only the last one counts in debt balancing.

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 (Lightning 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 (Lightning Draw) or the group votes on the rule — winner pays or loser pays. You can also play cards to tip the odds before the draw. Two express modes come on top: the finger picker and the team match inside events.

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 and all your data is something you do yourself from the app. 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.
