# Language Learning vs CertBook

The clearest difference is ads: CertBook at none against Language Learning's shown. CertBook also leads on update cadence (every 2 days vs every 6 days). Language Learning's advantage is chart position (#85 vs unranked) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Language Learning sells 15 in-app purchases, starting at $14.99 per month and CertBook sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Language Learning ships an update every 6 days, CertBook every 2 days. The most recent releases landed on October 15, 2026 and October 3, 2026 respectively.
