# Interval Timer vs HIIT Timer Pro

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

Both are free to download. Interval 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: Interval Timer has 296 ratings behind it against 1, so its average is the more settled of the two.

Interval Timer ships an update fortnightly, HIIT Timer Pro every 9 days. The most recent releases landed on October 12, 2026 and September 26, 2026 respectively.
