# Timeline vs Interval Timer X Workout Timer

The clearest difference is ads: Timeline at none against Interval Timer X Workout Timer's shown. Timeline also leads on monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.6). Interval Timer X Workout Timer's advantage is update cadence (every 6 weeks vs every 22 months) and ratings volume (686 vs 9). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Timeline sells 1 one-off in-app purchase and Interval Timer X Workout Timer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Interval Timer X Workout Timer holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Interval Timer X Workout Timer has 686 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Timeline's written reviews are positive against 94% of Interval Timer X Workout Timer's, so the app with the better star average is not the one people write more warmly about.

Timeline ships an update every 22 months, Interval Timer X Workout Timer every 6 weeks. The most recent releases landed on September 22, 2026 and September 29, 2026 respectively.
