This counter app prioritizes ease of use with large buttons for intuitive operation. Simply tap a button to easily record counts, and with each press, the current occurrence rate and probability are automatically calculated in real time. Grasp the situation on the spot without worrying about complex calculations. Furthermore, it includes a dedicated page that calculates probabilities using the binomial distribution. Based on the actual number of occurrences and the expected occurrence rate, you can see the numerical value representing “the probability this result would occur.” Don't rely solely on intuition—make probability and numbers your allies.
