# Interval Timer vs Phyzseek

The clearest difference is monetization model: Interval Timer at free with in-app purchases against Phyzseek's subscription. Interval Timer also leads on ratings volume (19K vs 86) and update cadence (every 9 days vs every 5 weeks). Phyzseek's advantage is ads (none vs shown) and review sentiment (84% vs 73%). On price, rating and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Phyzseek sells 3 in-app purchases, starting at $12.99 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 — 4.5 for Interval Timer against 4.4 for Phyzseek. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 86, so its average is the more settled of the two. Written reviews are what separate them: 73% of Interval Timer's written reviews are positive against 84% of Phyzseek's.

Interval Timer ships an update every 9 days, Phyzseek every 5 weeks. The most recent releases landed on September 30, 2026 and September 18, 2026 respectively.
