# 오답케어 vs 2Planner

The clearest difference is ads: 오답케어 at none against 2Planner's shown. 2Planner's advantage is update cadence (every 10 days vs every 4 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 오답케어 sells 2 in-app purchases, starting at $6.99 per month and 2Planner sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

오답케어 ships an update every 4 weeks, 2Planner every 10 days. The most recent releases landed on August 26, 2026 and September 20, 2026 respectively.
