ListShuffler turns your endless lists into a single pick — never argue about what to do next again. **THE PROBLEM** "What's for dinner?" Twenty minutes pass. Same question every Friday. Restaurants to try, movies to watch, chores to split — decisions pile up and no one picks. **WHY A COIN FLIP ISN'T ENOUGH** A coin handles two options. A random number generator forgets your list the moment you close it. You re-type the same names week after week, and weighing favorites is impossible. **THE SOLUTION** ListShuffler remembers your lists. Make a category for anything — restaurants, names, tasks, dares — and tap shuffle to get one pick. Weight items so favorites come up more, save templates for recurring decisions, and share lists over iCloud so friends and family pick together. Everything syncs across iPhone and iPad. Simple. Fair. Decision made.

Verdict
The clearest difference is price: ListShuffler at Free against Formalize's $1.99. ListShuffler also leads on rating (3.8 vs 2.6) and update cadence (every 2 months vs every 9 months). Formalize's advantage is ads (none vs shown) and iOS requirement (12.0 vs 18.0). On ratings volume, in-app purchases and device support there is nothing between them.
