The rankings, probability metrics, annualized rates, and valuation ranges are model-based estimates for research comparison only — not investment advice, trading instructions, forecasts, or guarantees. Put-side and Call-side labels identify research views; they do not execute an order. Options Explorer is for education and information only, and options involve substantial risk; consult a qualified professional before acting.

If no ad is available, the summary opens directly. An optional one-time Remove Ads in-app purchase removes ads, including these rewarded-ad prompts. Restore Purchases is available in Settings. No recurring subscription is required.

Verdict

The call

The clearest difference is in-app purchases: 元大 Fast at none against Options Explorer's 1. 元大 Fast also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.1). Options Explorer's advantage is update cadence (every 2 days vs every 3 weeks). On price and device support there is nothing between them.
