# Intervals Pro vs Round Timer

Round Timer's advantage is iOS requirement (15.0 vs 17.5). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month and Round Timer sells 8 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 296, so its average is the more settled of the two. Written reviews are what separate them: 84% of Intervals Pro's written reviews are positive against 73% of Round Timer's.
