# HIIT vs Circuit Training Workout

The clearest difference is iOS requirement: Circuit Training Workout at 12.0 against HIIT's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days and Circuit Training Workout sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
