Let It Drop

Big decision? Small decision? Let a ball decide. Let It Drop is your offline little gremlin for the moments when you really, really can't pick. A ball that actually drops This isn't a number an algorithm spits at you. Watch a single ball clatter through a peg grid and settle into one of your slots — the same physical, slightly chaotic feeling as the carnival game it's named after. You'll trust the result because you saw it happen. Doodle your options, don't type them Forget keyboards. Sketch a face, scribble a word, draw a tiny diagram — whatever your hand wants. Each option lives as a small hand-drawn tile, so "the spicy place" and "Mom's cooking" never look the same and never get confused. No IME, no autocorrect, no AI guessing what you meant. Just pictures only you understand. Pick one. Or pick three. Or pick five. Most decisions are "choose one of these," but some are "choose three from ten" — lottery numbers, lunch teammates, a band lineup, a draft order. Set how many balls drop and how many slots they fill. Let It Drop handles both with the same calm physics. Chain groups for big, weird, beautiful decisions String multiple option groups together so one drop feeds the next. Pick a restaurant type, then pick a place. Pick a movie genre, then a decade, then a specific film. Pick three friends to invite, then pick the activity. The setup is yours — limited only by your imagination. Made for *People who can't decide what to have for lunch. * Couples and friends stuck on Saturday-night plans. * Tabletop GMs generating random encounters and loot drops. * Teachers running classroom raffles and cold-call lotteries. * Anyone tired of "let me think about it" answers. Private by design * Fully offline — no internet required. * No accounts, no signups, no analytics, no ads. * Your sketches stay on your device. * The shareable result image is built locally and only sent if you choose to share it. Drop the ball. Let it go.
