The clearest difference is ratings volume: Calflow at 129 against Decendium's 2. Calflow also leads on device support (4 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calflow sells 3 in-app purchases, starting at $3.99 per month and Decendium sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
