Full description

The "Probability Calculator" is an app that allows you to simulate gacha probabilities. Main Features: Detailed Probability Calculation: By setting the win rate (probability of getting the desired item), the number of pulls (attempts), and the desired number of times you want to obtain the item, you can calculate the probability of getting it at least once, and estimate the number of pulls or cost required to achieve your desired number of hits. Result Visualization: Calculation results are displayed clearly and are easy to understand. Cost Calculation: You can also calculate the cost involved per pull, helping you understand how many attempts you can make within your budget. Recommended for: Players who want to simulate probabilities before pulling on a new gacha. Players who want to know roughly how much they might need to spend (via in-app purchases) to get the item they want. Anyone interested in probability calculations. How to Use: Enter the win rate, number of pulls, desired number of hits, and (optionally) the cost per pull. Tap the "Submit" button. Check the results. Please Note: This app is strictly a simulator and does not guarantee actual gacha results. Please use the calculation results as a guideline or estimate only.
