# Lemma vs Coding School

The clearest difference is update cadence: Coding School at every 3 weeks against Lemma's every 4 months. Coding School also leads on iOS requirement (17.6 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Lemma sells 1 in-app purchase, starting at $4.99 per month and Coding School sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Lemma ships an update every 4 months, Coding School every 3 weeks. The most recent releases landed on September 8, 2026 and September 10, 2026 respectively.
