# Interval Timer vs ChronoSport

The clearest difference is ads: ChronoSport at none against Interval Timer's shown. ChronoSport also leads on review sentiment (85% vs 73%). Interval Timer's advantage is update cadence (every 9 days vs every 8 months) and ratings volume (19K vs 39). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and ChronoSport sells 4 one-off in-app purchases. 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 4.6 for ChronoSport. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 39, 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 85% of ChronoSport's.

Interval Timer ships an update every 9 days, ChronoSport every 8 months. Both last shipped on October 3, 2026.
