Verdict
The clearest difference is in-app purchases: 2PD at none against IELTS Prep App's 1. 2PD also leads on ads (none vs shown) and rating (5.0 vs 4.6). IELTS Prep App's advantage is ratings volume (602 vs 2) and iOS requirement (15.0 vs 17.6). On price and device support there is nothing between them.
