抽選・ランダム決定ツール - No-login random decision tools for events & class
by•
Key details:
Uses the browser’s cryptographic RNG (Web Crypto) for fairness
No login / no email — data is processed locally on the device
Mobile-first UI, plus fullscreen mode for projector use
One-tap copy of results
I’d love feedback on: (1) usability on mobile, (2) any confusing wording, and (3) feature requests (e.g., weighting, history, shareable links).
Note: the UI is currently Japanese-first; if that’s a blocker, tell me and I’ll prioritize an English toggle.
