Verdict
The clearest difference is ads: Petroleum Engineering+ at none against IELTS Prep App's shown. Petroleum Engineering+ also leads on rating (5.0 vs 4.7). IELTS Prep App's advantage is ratings volume (710 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. IELTS Prep App sells 15 in-app purchases, starting at $4.99 per 7 days and Petroleum Engineering+ sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
