# Strflow vs Constella

The clearest difference is rating: Strflow at 5.0 against Constella's 4.8. Strflow also leads on ratings volume (49 vs 8) and review sentiment (97% vs 88%). Constella's advantage is iOS requirement (16.4 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Strflow sells 4 in-app purchases, starting at $1.49 per month and Constella sells 6 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
