# RayLab vs 212

The clearest difference is rating: RayLab at 4.7 against 212's 1.0. RayLab also leads on ratings volume (67 vs 1) and update cadence (every 6 weeks vs every 4 months). 212's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, monetization model 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. 212 asks for nothing beyond the download.

RayLab holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: RayLab has 67 ratings behind it against 1, so its average is the more settled of the two.

RayLab ships an update every 6 weeks, 212 every 4 months. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
