Randomizer Pro

One tap, any outcome. Randomizer Pro is the one app for every "I can't decide" moment — pickers for the boring stuff, chance for the fun stuff, and games for when you want company. PICK SOMETHING - Number — any range you set - Code — PINs, OTPs, lock codes - Percent — 0 to 100, to two decimals - String — random passwords and gibberish - Names — draw from your own list, no repeats until everyone's had a turn - Contact — a random person from your address book to text back LEAVE IT TO CHANCE - Dice — roll one or a handful, with a real tumble and bounce - Head or Tail — the oldest tiebreaker there is - Card — draw from a full 52-card deck - Wheel — spin your own options, weighted so it's still fair over time - Photo — surface a random photo or video you forgot you had PLAY THE COMPUTER - Rock Paper Scissors — against an opponent that studies your patterns on-device and gets sharper the more you play - Higher or Lower — same idea: it reads how you call, and the draws get tougher as it learns you - Guess the Number — warmer/colder and higher/lower hints, scored against par like golf PLAY WITH SOMEONE - Truth or Dare — pass-and-play for two, plus room to add your own questions - Reflex Duel — split-screen, fastest thumb wins the round - Who Pays? — settles the bill with a fairness system that remembers who paid last, not just a coin flip PRIVATE BY DESIGN Nothing you type or pick ever leaves your phone. Contacts and Photos are read on-device only. The on-device AI in Rock Paper Scissors and Higher or Lower trains and runs locally — none of your gameplay is ever uploaded anywhere. No account, no sign-in, no tracking your choices. Every screen keeps its own history, so you can see what came up before, settle an argument about whether it's really been fair, and pick up right where you left off. Randomizer Pro. One tap, any outcome.

Verdict
The clearest difference is in-app purchases: Randomizer Pro at none against NumGen Pro's 1. NumGen Pro's advantage is update cadence (monthly vs every 10 months) and iOS requirement (15.5 vs 18.0). On price, ads and device support there is nothing between them.
