Verdict
The clearest difference is price: Ai2 OLMoE at Free against Textella's $1.99. Ai2 OLMoE also leads on ratings volume (17 vs 1) and device support (3 vs 1). Textella's advantage is review sentiment (100% vs 78%) and update cadence (every 3 weeks vs every 2 months). On rating, ads, in-app purchases and iOS requirement there is nothing between them.
