# 칼로바이 vs 운동닥터

The clearest difference is ads: 운동닥터 at none against 칼로바이's shown. 운동닥터 also leads on monetization model (free vs free with in-app purchases) and review sentiment (70% vs 49%). 칼로바이's advantage is rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

칼로바이 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 운동닥터 has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 49% of 칼로바이's written reviews are positive against 70% of 운동닥터's, so the app with the better star average is not the one people write more warmly about.

칼로바이 ships an update every 3 weeks, 운동닥터 every 2 weeks. The most recent releases landed on October 15, 2026 and October 18, 2026 respectively.
