# 平行世界 vs Simple

The clearest difference is rating: Simple at 4.6 against 平行世界's 3.7. Simple also leads on update cadence (every 4 days vs every 6 weeks). 平行世界's advantage is review sentiment (71% vs 57%) and iOS requirement (12.0 vs 15.5). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. 平行世界 sells 4 one-off in-app purchases and Simple sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Simple holds the better App Store score, 4.6 against 3.7. Both are backed by a comparable volume of ratings — 13 and 10 respectively. Written reviews complicate that: 71% of 平行世界's written reviews are positive against 57% of Simple'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, Simple every 4 days. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
