# Lost World vs Bit Builder

The clearest difference is review sentiment: Lost World at 77% against Bit Builder's 41%. Bit Builder's advantage is update cadence (monthly vs every 36 months) and rating (3.8 vs 3.5). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Bit Builder holds the better App Store score, 3.8 against 3.5. That said, the two scores are not equally well evidenced: Bit Builder has 548 ratings behind it against 90, so its average is the more settled of the two. Written reviews complicate that: 77% of Lost World's written reviews are positive against 41% of Bit Builder's, so the app with the better star average is not the one people write more warmly about.

Lost World ships an update every 36 months, Bit Builder monthly. The most recent releases landed on October 1, 2026 and October 13, 2026 respectively.
