# Interval Timer vs Timeline

The clearest difference is ads: Timeline at none against Interval Timer's shown. Timeline also leads on review sentiment (100% vs 73%) and monetization model (free vs free with in-app purchases). Interval Timer's advantage is update cadence (every 9 days vs every 22 months) and ratings volume (19K vs 9). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Timeline sells 1 one-off in-app purchase. 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 Timeline. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 9, 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 100% of Timeline's.

Interval Timer ships an update every 9 days, Timeline every 22 months. The most recent releases landed on October 9, 2026 and September 22, 2026 respectively.
