# 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 update cadence (every 9 days vs every 2 months). Interval Timer's advantage is ratings volume (246 vs 1) and device support (4 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Interval Timer sells 1 one-off in-app purchase 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.

On the App Store both sit at effectively the same score — 4.9 for Interval Timer against 5.0 for HIIT Timer Pro. That said, the two scores are not equally well evidenced: Interval Timer has 246 ratings behind it against 1, so its average is the more settled of the two.

Interval Timer ships an update every 2 months, HIIT Timer Pro every 9 days. The most recent releases landed on September 23, 2026 and September 26, 2026 respectively.
