# 이투스 수강앱 vs 검정기출

The clearest difference is review sentiment: 검정기출 at 76% against 이투스 수강앱's 13%. 검정기출 also leads on update cadence (every 10 days vs every 2 months). 이투스 수강앱's advantage is monetization model (free vs free with in-app purchases).

Both are free to download. 이투스 수강앱 sells 1 one-off in-app purchase and 검정기출 sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
