Verdict
The clearest difference is rating: tecla at 5.0 against Envision AI's 4.2. tecla also leads on review sentiment (100% vs 58%) and iOS requirement (11.0 vs 16.6). Envision AI's advantage is ratings volume (595 vs 1) and update cadence (every 5 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
