Verdict

The call

The clearest difference is review sentiment: Thrive Studies at 100% against Operation World's 86%. Thrive Studies also leads on update cadence (every 2 months vs every 3 months). Operation World's advantage is rating (4.5 vs 4.3) and ratings volume (50 vs 13). On price, ads, in-app purchases and monetization model there is nothing between them.
