Verdict
The clearest difference is in-app purchases: Khan Academy at none against Deeply's 1. Khan Academy also leads on ads (none vs shown) and ratings volume (112K vs 4). Deeply's advantage is rating (5.0 vs 4.6) and update cadence (every 5 days vs every 6 weeks). On price, device support and iOS requirement 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. Deeply sells 1 in-app purchase, starting at $9.99 per month. Khan Academy asks for nothing beyond the download.
Deeply holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Khan Academy has 112K 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 Deeply's.
Khan Academy ships an update every 6 weeks, Deeply every 5 days. The most recent releases landed on October 21, 2026 and October 14, 2026 respectively.
