# 국어 vs Start Math

The clearest difference is ads: Start Math at none against 국어's shown. Start Math also leads on update cadence (every 2 days vs fortnightly). 국어's advantage is iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 국어 sells 5 in-app purchases, starting at $5.99 per month and Start Math sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

국어 ships an update fortnightly, Start Math every 2 days. The most recent releases landed on October 8, 2026 and October 13, 2026 respectively.
