# KB부동산 vs Soma by zigbang

The clearest difference is rating: Soma by zigbang at 5.0 against KB부동산's 3.6. KB부동산's advantage is review sentiment (83% vs 45%) and ratings volume (18 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Soma by zigbang holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: KB부동산 has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of KB부동산's written reviews are positive against 45% of Soma by zigbang's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
