Rounds Timer for CrossFit also leads on rating (4.9 vs 4.7) and iOS requirement (16.2 vs 18.6). Interval Flow's advantage is ratings volume (168 vs 8).

Both are free to download. Rounds Timer for CrossFit sells 2 in-app purchases, starting at $1.99 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.
