# 装修预算表 vs SunSim Building

The clearest difference is monetization model: 装修预算表 at free against SunSim Building's free with in-app purchases. 装修预算表 also leads on update cadence (every 5 days vs every 3 weeks) and rating (5.0 vs 4.7). SunSim Building's advantage is review sentiment (64% vs 44%) and iOS requirement (13.0 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. 装修预算表 sells 1 one-off in-app purchase and SunSim Building sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

装修预算表 holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 44% of 装修预算表's written reviews are positive against 64% of SunSim Building's, so the app with the better star average is not the one people write more warmly about.

装修预算表 ships an update every 5 days, SunSim Building every 3 weeks. The most recent releases landed on September 26, 2026 and September 23, 2026 respectively.
