# RayLab vs KaleidoTile

The clearest difference is rating: RayLab at 4.7 against KaleidoTile's 4.1. RayLab also leads on update cadence (every 6 weeks vs every 7 months) and ratings volume (67 vs 7). KaleidoTile's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. RayLab sells 10 in-app purchases, starting at $3.99 per month. KaleidoTile asks for nothing beyond the download.

RayLab holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: RayLab has 67 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 75% of RayLab's written reviews are positive against 67% of KaleidoTile's.

RayLab ships an update every 6 weeks, KaleidoTile every 7 months. The most recent releases landed on October 20, 2026 and October 12, 2026 respectively.
