# Timer vs Scrap Science

The clearest difference is price: Scrap Science at Free against Timer's $3.99. Scrap Science also leads on update cadence (every 2 weeks vs every 7 months) and review sentiment (100% vs 80%). Timer's advantage is rating (4.8 vs 4.3) and in-app purchases (none vs 6). On ads and device support there is nothing between them.

Scrap Science is free to download; Timer costs $3.99 up front. Scrap Science sells 6 in-app purchases, starting at $9.99 per month. Timer asks for nothing beyond the download.

Timer holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Timer has 218 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of Timer's written reviews are positive against 100% of Scrap Science's, so the app with the better star average is not the one people write more warmly about.

Timer ships an update every 7 months, Scrap Science every 2 weeks. The most recent releases landed on September 22, 2026 and June 11, 2026 respectively.
