Verdict
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.
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. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
