# Read Live vs Metabolism Sim

The clearest difference is rating: Read Live at 5.0 against Metabolism Sim's 3.2. Metabolism Sim's advantage is review sentiment (57% vs 29%) and ratings volume (71 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Read Live holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Metabolism Sim has 71 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 29% of Read Live's written reviews are positive against 57% of Metabolism Sim's, so the app with the better star average is not the one people write more warmly about.

Read Live ships an update every 4 months, Metabolism Sim every 3 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
