Verdict
The clearest difference is in-app purchases: Twirdora at none against RAVON's 17. Twirdora also leads on review sentiment (100% vs 67%) and iOS requirement (12.0 vs 15.0). RAVON's advantage is ratings volume (84 vs 12). On price, rating, update cadence and ads there is nothing between them.

On the App Store both sit at effectively the same score — 4.8 for RAVON against 4.9 for Twirdora.
