Verdict
The clearest difference is in-app purchases: Permutation and Combination at none against iClicker Student's 8. Permutation and Combination also leads on review sentiment (44% vs 17%) and device support (3 vs 1). iClicker Student's advantage is update cadence (every 6 weeks vs every 40 months) and ratings volume (37K vs 13). On price and ads there is nothing between them.

Both are free to download. iClicker Student sells 8 one-off in-app purchases. Permutation and Combination asks for nothing beyond the download.
iClicker Student holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: iClicker Student has 37K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 17% of iClicker Student's written reviews are positive against 44% of Permutation and Combination's, so the app with the better star average is not the one people write more warmly about.
iClicker Student ships an update every 6 weeks, Permutation and Combination every 40 months. The most recent releases landed on September 26, 2026 and September 10, 2026 respectively.
