# 青蛙Todo vs Calflow

The clearest difference is ratings volume: Calflow at 121 against 青蛙Todo's 7. 青蛙Todo's advantage is review sentiment (100% vs 88%) and iOS requirement (15.5 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 青蛙Todo sells 11 in-app purchases, starting at $1.99 per month and Calflow sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for 青蛙Todo against 4.9 for Calflow. That said, the two scores are not equally well evidenced: Calflow has 121 ratings behind it against 7, so its average is the more settled of the two.
