Context

Bolão was a personal, internal project used by Plinio and friends to compare winner predictions. The source app is Bolão Copa 2026, with FIFA World Cup 2026 group and knockout phases. It is not presented as a commercial product.

Core flow

The app provides group-stage match predictions and knockout navigation. Participants can create an account, save predictions, return to them and compare results through ranking.

  1. Create account
  2. Submit and save predictions
  3. Return to persisted entries
  4. Compare group results

Persistence model

Login, signup and recovery share one account screen. Authenticated predictions are saved to the account, and local predictions can be imported when signing in. The captures show only signed-out public interfaces; no participant data or ranking results are shown.

Why it existed

The project existed to make an informal competition among friends easier to manage and determine who had the most correct winner predictions.

Let's build something people don't have to think about.

The best products feel obvious. That is what I aim to design.
