User reviews

User interface

Updated review. Update to iOS 14 was very much appreciated. UI colors make it hard to read text in boxes and results. Otherwise it works. Suggest using system color and dark mode coloring to improve UI and user experience.

Response from developer

Thanks for your input SamG5V6. We just updated the app to what we hope are improved contrasting colors.

Response from developer

We are concerned that you cannot get the app to work for you. It was designed for users who have had exposure to probabilities and Bayes’ Theorem in the hope that it would simplify problem set up and calculations. We suggest that you review the sample problems and enter the sample problem data in the app. You will find that the calculations are correct. We have provided a number of sample problems with the app in the hope that they will guide you to set up your particular problem. As mentioned in the app, the difficulty with applying Bayes’ Theorem is problem set up. Once you have defined your problem, the calculations are quite simple. Again, we are sorry that you are having issues and hope this information will help you utilize the app.
