Fluky makes random decisions fair, fast and fun. Spin a wheel, flip a coin, roll dice, split teams or run a Secret Santa draw. One free app, no account, no ads. SPIN WHEEL Add your options, spin and get a winner. Remove the winner and spin again, save your wheels, or share a wheel with a link that also opens on fluky.com. SECRET SANTA Type the names, add pairs who shouldn't draw each other (couples, siblings), and draw. Everyone gets a private link that shows only who they're buying for. Not even the organizer can see who drew whom. Participants can add a wishlist, and you can still add or remove people after the draw. Everything is deleted automatically after the event. MORE TOOLS • Yes or no wheel: one spin, one clear answer • Name picker: paste names, pick one at random • Team generator: split people into fair random teams • Random number: any range, unique numbers if you want • Dice roller: roll one or many dice • Coin flip: heads or tails in one tap • Random facts: a surprising fact on demand FAIR BY DESIGN Every result comes from the system's cryptographically secure random number generator, so no option is ever favored. Available in English, Español, Čeština, Português and 繁體中文. Works with the same Secret Santa groups and wheel links as fluky.com.

Verdict
The clearest difference is iOS requirement: Fluky at 18.0 against Resistor's 26.0. On price, ads, in-app purchases and device support there is nothing between them.
