# Stitch Loop vs 37

The clearest difference is rating: 37 at 5.0 against Stitch Loop's 4.5. 37 also leads on in-app purchases (none vs 10) and ratings volume (25 vs 2). Stitch Loop's advantage is update cadence (every 3 days vs every 3 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Stitch Loop sells 10 one-off in-app purchases. 37 asks for nothing beyond the download.

37 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: 37 has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
