# Scale vs Interval Timer

The clearest difference is ads: Interval Timer at none against Scale's shown. Interval Timer also leads on update cadence (every 2 days vs every 2 weeks). Scale's advantage is iOS requirement (12.0 vs 18.5). On price, in-app purchases and device support there is nothing between them.

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

Scale ships an update every 2 weeks, Interval Timer every 2 days. The most recent releases landed on September 10, 2026 and June 1, 2026 respectively.
