Verdict

The call

The clearest difference is rating: Ibis Prep at 5.0 against Khan Academy's 4.6. Ibis Prep also leads on review sentiment (100% vs 74%) and update cadence (fortnightly vs every 6 weeks). Khan Academy's advantage is ratings volume (110K vs 4) and chart position (#66 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Ibis Prep holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 74% of Khan Academy's written reviews are positive against 100% of Ibis Prep's.

UpkeepUpdate frequency

Khan Academy ships an update every 6 weeks, Ibis Prep fortnightly. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
