# ToolScanner vs Spool

The clearest difference is rating: Spool at 5.0 against ToolScanner's 4.0. Spool also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (5 vs 1). ToolScanner's advantage is iOS requirement (15.1 vs 26.1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. ToolScanner sells 3 one-off in-app purchases and Spool sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Spool holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Spool has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
