Ghost Detector Talk To Spirits is a free iPhone app that lets users find and communicate with ghosts and spirits. The app is developed by Nguyen Thuy and is available in the Lifestyle category of the App Store.

To use the app, simply start it and walk around. When the app detects a ghost, move your smartphone slowly until you see it between the lines on the radar. Then, type your question and wait for the spirit to answer. For the best experience, use the app in the dark.

It's important to note that the app is intended for entertainment purposes only and cannot guarantee that it communicates with real spirits. The app does not actually provide ghost detection functionality.

For those who want to access full ghost detector features, there is a Ghost Detector Pro subscription available for $3.99 USD weekly. This subscription includes higher speed, the ability to ask more than 40 questions per day, no popup-ads, and more spirits added regularly.

Overall, Ghost Detector Talk To Spirits is an interesting app for those who are interested in the paranormal. However, it should be used for entertainment purposes only and not taken too seriously.
