# Learn HTML vs Otum

The clearest difference is in-app purchases: Learn HTML at none against Otum's 1. Learn HTML also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Otum's advantage is ads (none vs shown) and update cadence (every 5 days vs every 2 months). On price there is nothing between them.

Learn HTML ships an update every 2 months, Otum every 5 days. The most recent releases landed on October 24, 2026 and October 16, 2026 respectively.
