# Water vs Interval Flow

Water's advantage is iOS requirement (16.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Water sells 5 in-app purchases, starting at $0.99 per month and Interval Flow sells 10 in-app purchases, starting at $4.99 per 3 months. Whichever you choose, the download price is not the number that matters.
