OptionRadar turns complex option chains into clean, actionable snapshots. Enter a U.S. ticker to see the top call and put strikes by open interest (or volume), their contract counts, and an auto-generated bullish/bearish bias for up to three upcoming expirations. The app fetches data directly from Yahoo Finance, handles throttling gracefully, and keeps everything on-device—no accounts, no back end. Built for clarity with multi-language support, a promo hub, and configurable settings for alternative data sources and refresh cadence
