# 루션 vs Calog

The clearest difference is in-app purchases: 루션 at none against Calog's 17. 루션 also leads on rating (5.0 vs 4.7). Calog's advantage is ratings volume (41 vs 4) and update cadence (every 4 days vs every 9 days). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Calog sells 14 in-app purchases, starting at $9.99 per month. 루션 asks for nothing beyond the download.

루션 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Calog has 41 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of 루션's written reviews are positive against 81% of Calog's, so the app with the better star average is not the one people write more warmly about.

루션 ships an update every 9 days, Calog every 4 days. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
