# Yitan Yun vs LumenIZE

The clearest difference is ratings volume: LumenIZE at 66 against Yitan Yun's 13. On price, rating, review sentiment and update cadence there is nothing between them.

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

LumenIZE holds the better App Store score, 1.6 against 1.5. That said, the two scores are not equally well evidenced: LumenIZE has 66 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 17% of Yitan Yun's written reviews are positive against 10% of LumenIZE's, so the app with the better star average is not the one people write more warmly about.

Yitan Yun ships an update every 5 weeks, LumenIZE every 2 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
