# IELTS Develop vs CELPIP English Test Prep

The clearest difference is ads: CELPIP English Test Prep at none against IELTS Develop's shown. CELPIP English Test Prep also leads on iOS requirement (13.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. IELTS Develop sells 6 one-off in-app purchases and CELPIP English Test Prep sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
