RNGadget is the best way to generate random numbers on iOS! It offers a variety of basic and advanced modes to help you generate numbers in as many ways as I could think of. Basic Modes: - Numbers: Generate a single random number using only a minimum and maximum number. The simplest way to generate numbers. - Coins: Flip a series of coins! Flip up to 50 consecutive coins with fancy haptics. - Dice: Generate numbers using up to 9 standard 6-sided dice. - Cards: Generate numbers by drawing a hand of up to 7 cards. Optionally, you can display the point values of each card drawn, with the Ace being toggleable between 1 and 11 points. - Marbles: Generate up to 9 letters by rolling some marbles. (Kind of like when you play bingo.) Advanced Modes: - Dealer: Deal a deck of cards out to a set number of hands. All basic modes are also available in a smaller form (fewer coins, dice, cards, and marbles) on Apple Watch, for when you need to flip a coin or roll some dice in a pinch.

Verdict
The clearest difference is in-app purchases: RNGadget at none against Randomizer's 4. RNGadget also leads on ads (none vs shown). Randomizer's advantage is iOS requirement (13.0 vs 15.6). On price and device support there is nothing between them.
