# LadderTouchLite vs Stray Scanner

The clearest difference is rating: Stray Scanner at 5.0 against LadderTouchLite's 4.7. LadderTouchLite's advantage is ratings volume (226 vs 5) and update cadence (every 2 months vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Stray Scanner holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LadderTouchLite has 226 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 89% of LadderTouchLite's written reviews are positive against 75% of Stray Scanner's, so the app with the better star average is not the one people write more warmly about.

LadderTouchLite ships an update every 2 months, Stray Scanner every 6 months. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
