# Core vs Workout Timer

The clearest difference is in-app purchases: Workout Timer at none against Core's 3. Workout Timer also leads on update cadence (every 4 weeks vs every 33 months) and ratings volume (24 vs 4). Core's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price and device support there is nothing between them.

Both are free to download. Core sells 3 in-app purchases, starting at $1.99 per month. Workout Timer asks for nothing beyond the download.

Core holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Workout Timer has 24 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Core's written reviews are positive against 80% of Workout Timer's.

Core ships an update every 33 months, Workout Timer every 4 weeks. The most recent releases landed on October 30, 2026 and October 22, 2026 respectively.
