# FlagWaver vs Algodoo

The clearest difference is in-app purchases: Algodoo at none against FlagWaver's 10. Algodoo also leads on update cadence (monthly vs every 15 months) and rating (3.8 vs 3.4). FlagWaver's advantage is price ($0.99 vs $7.99). On review sentiment, ads and device support there is nothing between them.

FlagWaver costs $0.99 and Algodoo $7.99 up front. FlagWaver sells 10 one-off in-app purchases. Algodoo asks for nothing beyond the download.

Algodoo holds the better App Store score, 3.8 against 3.4. That said, the two scores are not equally well evidenced: Algodoo has 878 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 62% of FlagWaver's written reviews are positive against 59% of Algodoo's, so the app with the better star average is not the one people write more warmly about.

FlagWaver ships an update every 15 months, Algodoo monthly. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
