Verdict
The clearest difference is in-app purchases: Stacks Timer at none against Wroom's 9. Stacks Timer also leads on review sentiment (80% vs 69%) and iOS requirement (8.0 vs 12.0). Wroom's advantage is rating (4.3 vs 4.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Wroom sells 9 one-off in-app purchases. Stacks Timer asks for nothing beyond the download.
Wroom holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 10 and 15 respectively. Written reviews complicate that: 80% of Stacks Timer's written reviews are positive against 69% of Wroom's, so the app with the better star average is not the one people write more warmly about.
Stacks Timer ships an update every 11 months, Wroom every 17 months. The most recent releases landed on September 30, 2026 and October 2, 2026 respectively.
