# 모두닥 vs 데카르트

The clearest difference is in-app purchases: 모두닥 at none against 데카르트's 10. 모두닥 also leads on ratings volume (57 vs 2). 데카르트's advantage is review sentiment (80% vs 50%) and update cadence (every 5 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 데카르트 sells 10 in-app purchases, starting at $6.99 per month. 모두닥 asks for nothing beyond the download.

데카르트 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 모두닥 has 57 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of 모두닥's written reviews are positive against 80% of 데카르트's.

모두닥 ships an update every 5 weeks, 데카르트 every 5 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
