Verdict
The clearest difference is rating: Codon at 5.0 against iClicker Student's 4.4. Codon also leads on update cadence (every 3 weeks vs every 6 weeks). iClicker Student's advantage is ratings volume (38K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iClicker Student sells 8 one-off in-app purchases and Codon sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Codon holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: iClicker Student has 38K ratings behind it against 1, so its average is the more settled of the two.
iClicker Student ships an update every 6 weeks, Codon every 3 weeks. The most recent releases landed on November 12, 2026 and November 10, 2026 respectively.
