# Interval Timer Sec+Sec vs Loop

The clearest difference is rating: Loop at 4.5 against Interval Timer Sec+Sec's 3.7. Loop also leads on ads (none vs shown) and update cadence (every 10 days vs every 12 months). Interval Timer Sec+Sec's advantage is in-app purchases (none vs 3) and review sentiment (78% vs 63%). On price there is nothing between them.

Both are free to download. Loop sells 3 in-app purchases, starting at $0.99 per month. Interval Timer Sec+Sec asks for nothing beyond the download.

Loop holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Loop has 67 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 78% of Interval Timer Sec+Sec's written reviews are positive against 63% of Loop's, so the app with the better star average is not the one people write more warmly about.

Interval Timer Sec+Sec ships an update every 12 months, Loop every 10 days. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
