Verdict

The call

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.

UpkeepUpdate frequency

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.
