# Seconds Interval Timer vs Best Interval Timer

The clearest difference is rating: Seconds Interval Timer at 4.7 against Best Interval Timer's 3.5. Seconds Interval Timer also leads on ratings volume (24K vs 10). Best Interval Timer's advantage is review sentiment (100% vs 75%) and update cadence (every 6 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Seconds Interval Timer sells 1 one-off in-app purchase and Best Interval Timer sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Seconds Interval Timer holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Seconds Interval Timer has 24K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 75% of Seconds Interval Timer's written reviews are positive against 100% of Best Interval Timer's, so the app with the better star average is not the one people write more warmly about.

Seconds Interval Timer ships an update monthly, Best Interval Timer every 6 days. Both last shipped on October 13, 2026.
