Verdict
The clearest difference is in-app purchases: Opura at none against Speech Central's 1. Opura also leads on review sentiment (100% vs 69%) and rating (5.0 vs 4.6). Speech Central's advantage is ratings volume (1.6K vs 5) and update cadence (every 9 days vs every 3 weeks). On price, ads and iOS requirement there is nothing between them.

Speech Central ships an update every 9 days, Opura every 3 weeks. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
