# 天天长高 vs 动起来鸭

The clearest difference is review sentiment: 天天长高 at 57% against 动起来鸭's 17%. 天天长高 also leads on rating (4.3 vs 4.0). 动起来鸭's advantage is ratings volume (21 vs 3) and iOS requirement (13.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 天天长高 sells 16 in-app purchases, starting at $2.99 per month and 动起来鸭 sells 12 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
