# IELTS Prep App vs 2PD

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.

Both are free to download. IELTS Prep App sells 1 one-off in-app purchase. 2PD asks for nothing beyond the download.

2PD holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: IELTS Prep App has 602 ratings behind it against 2, so its average is the more settled of the two.

IELTS Prep App ships an update every 20 months, 2PD every 2 months. The most recent releases landed on October 21, 2026 and October 6, 2026 respectively.
