# Khan Academy vs BrainDeck

The clearest difference is in-app purchases: Khan Academy at none against BrainDeck's 6. Khan Academy also leads on ratings volume (110K vs 244) and chart position (#65 vs unranked). BrainDeck's advantage is update cadence (every 6 days vs every 6 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. BrainDeck sells 6 in-app purchases, starting at $1.99 per 7 days. Khan Academy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Khan Academy against 4.7 for BrainDeck. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 244, so its average is the more settled of the two. Written reviews are what separate them: 74% of Khan Academy's written reviews are positive against 70% of BrainDeck's.

Khan Academy ships an update every 6 weeks, BrainDeck every 6 days. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
