Palpites do Bicho no Celular is an Android application developed by Júlio Lemos that generates random numbers for the popular Brazilian game called "jogo do bicho". The app contains advertisements, but a premium version is available without them.

The app also provides information about the game and its rules, including the 25 animal groups and their corresponding numbers. Each group is made up of four numbers, covering a total of 100 numbers. To determine which group an individual number belongs to, users can refer to the app's provided information. For example, the numbers 01, 02, 03, and 04 belong to the avestruz (ostrich) group.

It's important to note that this app does not encourage users to gamble, but merely provides information about the game and its animal groups and numbers.
