Store description excerpt
Lucky Draw Screen is a fully offline raffle app for annual parties, events, and live draws. No internet, no data collection — your employee roster never leaves the device. That's a privacy guarantee other lottery apps simply can't match. Why Lucky Draw Screen? Up to 20 participants, all features free. Most raffle apps go online, upload your participant list, and offer no way to verify fairness. Lucky Draw Screen does the opposite: fully offline, fair end to end, with results you can display and trace. Fair & transparent — show it to everyone Draws use the system-level cryptographic random source (SystemRandomNumberGenerator) with sampling without replacement, so no one wins twice in one round. There's no code-level backdoor for a "predetermined winner list." Results are open and verifiable — organizers stand behind them, employees trust them. Three modes, maximum ceremony Big Wheel — stops by physical inertia 3D Sphere — names roll as particles across a sphere Number Draw — rapid flash, then freeze Switch modes between segments to keep the energy high. Huge rosters, ready in seconds One-tap import from Excel, CSV, or text. Supports thousands of participants with zero lag.
