Generate fair random numbers with three distinct algorithms — each tuned for a different kind of randomness. • True Random — every number has equal chance every time. Great for raffles, lotteries, fair picks, and any moment you need an unbiased result. • Shuffled Deck — every number in your range is drawn exactly once before any repeats. Perfect for prize draws, picking winners without duplicates, classroom name pickers, and dealing cards. • Bell Curve — results cluster near the middle of your range following a normal distribution. Useful for dice-style mechanics, statistics teaching, and any scenario where extreme values should be rare. Features • Set any min/max range • View the history of generated numbers • Clean, fast SwiftUI interface built for iPhone Use cases • Roll dice for board games and tabletop RPGs (D&D, d20, custom dice) • Draw winners for raffles, contests, and giveaways • Pick a name from a list of students, teammates, or friends • Flip a coin or make a quick 50/50 decision • Generate lucky-style numbers (not affiliated with any official lottery) • Teach probability and statistics with three distributions side by side
