# RedX Stairs vs CutList Optimizer

The clearest difference is update cadence: CutList Optimizer at every 4 days against RedX Stairs's every 2 weeks. CutList Optimizer also leads on review sentiment (46% vs 26%). RedX Stairs's advantage is rating (4.5 vs 4.2) and ratings volume (426 vs 121). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. RedX Stairs sells 5 in-app purchases, starting at $9.99 per month and CutList Optimizer sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

RedX Stairs holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 426 and 121 respectively. Written reviews complicate that: 26% of RedX Stairs's written reviews are positive against 46% of CutList Optimizer's, so the app with the better star average is not the one people write more warmly about.

RedX Stairs ships an update every 2 weeks, CutList Optimizer every 4 days. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
