# 平行世界 vs 星泡

The clearest difference is rating: 平行世界 at 3.5 against 星泡's 2.3. 平行世界 also leads on ads (none vs shown) and ratings volume (11 vs 3). 星泡's advantage is update cadence (fortnightly vs every 6 weeks) and review sentiment (80% vs 71%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 平行世界 sells 4 one-off in-app purchases and 星泡 sells 14 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

平行世界 holds the better App Store score, 3.5 against 2.3. Both are backed by a comparable volume of ratings — 11 and 3 respectively. Written reviews complicate that: 71% of 平行世界's written reviews are positive against 80% of 星泡's, so the app with the better star average is not the one people write more warmly about.

平行世界 ships an update every 6 weeks, 星泡 fortnightly. The most recent releases landed on July 7, 2026 and September 27, 2026 respectively.
