# Clockwork vs Winder

The clearest difference is review sentiment: Winder at 100% against Clockwork's 43%. Winder also leads on rating (5.0 vs 4.4) and update cadence (every 5 days vs every 3 weeks). Clockwork's advantage is ratings volume (24 vs 2) and iOS requirement (16.4 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Clockwork sells 1 one-off in-app purchase and Winder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Winder holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Clockwork has 24 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 43% of Clockwork's written reviews are positive against 100% of Winder's.

Clockwork ships an update every 3 weeks, Winder every 5 days. The most recent releases landed on October 11, 2026 and September 27, 2026 respectively.
