Charlie Charlie is a free Android app developed by Hitcents under the Lifestyle category. The app is inspired by an ancient Mexican legend and lets users communicate with the spirit of Charlie by asking "Charlie Charlie are you there?".

The app features a simple interface that allows users to ask their own questions and see the pencils move in response. Charlie can hear users through their device's microphone, adding a realistic touch to the experience. However, users are warned to be careful with the questions they ask as Charlie can become angry depending on the nature of the question.

It is worth noting that the app was submitted for publication by a 14-year-old developer from Ecuador named Pao Gutiérrez, who passed away from medical complications shortly after submitting the app. The app is dedicated to his memory.

Overall, Charlie Charlie is an interesting app that offers a unique experience for those interested in paranormal activities. However, users should exercise caution when using the app and avoid asking inappropriate questions.
