# IELTS Prep App vs IELTS Flex

The clearest difference is ads: IELTS Flex at none against IELTS Prep App's shown. IELTS Flex also leads on rating (5.0 vs 4.7). IELTS Prep App's advantage is ratings volume (694 vs 1). 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 IELTS Flex sells 21 in-app purchases, starting at $68.99 per month. Whichever you choose, the download price is not the number that matters.

IELTS Flex holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: IELTS Prep App has 694 ratings behind it against 1, so its average is the more settled of the two.

IELTS Prep App ships an update monthly, IELTS Flex fortnightly. Both last shipped on September 28, 2026.
