# Tower Builder vs Water Power!

The clearest difference is review sentiment: Tower Builder at 100% against Water Power!'s 22%. Tower Builder also leads on ads (none vs shown) and update cadence (daily vs fortnightly). Water Power!'s advantage is ratings volume (25K vs 11). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Tower Builder sells 7 one-off in-app purchases and Water Power! sells 21 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Tower Builder holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Water Power! has 25K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 100% of Tower Builder's written reviews are positive against 22% of Water Power!'s.

Tower Builder ships an update daily, Water Power! fortnightly. The most recent releases landed on September 27, 2026 and October 16, 2026 respectively.
