# IntervalCoach vs Phase

The clearest difference is device support: IntervalCoach at 4 against Phase's 1. On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. IntervalCoach sells 4 in-app purchases, starting at $2.99 per month and Phase sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
