# My Chihiros vs LumenIZE

The clearest difference is update cadence: My Chihiros at every 9 days against LumenIZE's every 2 months. LumenIZE's advantage is rating (1.6 vs 1.4). On price, review sentiment, ratings volume and ads 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 1.4. Both are backed by a comparable volume of ratings — 65 and 67 respectively. Written reviews complicate that: 16% of My Chihiros'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.

My Chihiros ships an update every 9 days, LumenIZE every 2 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
