Cota Certa

No more losing control of group bets and raffles organized in your WhatsApp group! Cota Certa helps you organize everything clearly — who has already paid, how much has been raised, and what the result was.

🎯 GROUP BETS
Create a group bet, set the share value and the deadline. Each participant marks how many shares they want, and you confirm the payment whenever you want. The app shows the complete list: who joined, how many shares each person took, and how much has already been raised.

Indicate which lottery and contest the group is playing (Mega-Sena, Lotofácil, Quina, and others), register the bets — there can be several combinations in the same contest — and paste the proof link for everyone to check. After the draw, search for the official result directly in the app and see how many numbers came up in each bet.

🎟️ RAFFLES
Create numbered raffles with multiple prizes. Choose between randomly drawing from confirmed participants, or linking the draw to the official Federal Lottery result — with total transparency: the app shows the contest, the official ticket for each prize, and indicates when the drawn number needed to be approximated because it wasn't sold.

✅ EVERYTHING IN ONE PLACE
• Public or private groups, with a unique code
• Payment confirmation quota by quota
• Automatic notifications of new group bets and raffles
• Dark mode
• Direct sharing of results on WhatsApp
• No need to create an account or password

Organize transparently, without depending on spreadsheets or writing everything down in a notebook. Cota Certa takes care of the accounts so you can focus on what matters: the anticipation of the draw.
