# Round Timer vs HIIT Timer Pro

The clearest difference is ads: HIIT Timer Pro at none against Round Timer's shown. HIIT Timer Pro also leads on rating (5.0 vs 4.8) and update cadence (every 9 days vs every 3 weeks). Round Timer's advantage is ratings volume (296 vs 1) and device support (4 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Round Timer sells 8 in-app purchases, starting at $3.99 per month and HIIT Timer Pro sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

HIIT Timer Pro holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Round Timer has 296 ratings behind it against 1, so its average is the more settled of the two.
