# Insulator's Field Guide vs ScanCoin

The clearest difference is rating: ScanCoin at 4.7 against Insulator's Field Guide's 3.0. ScanCoin also leads on update cadence (every 4 days vs every 3 months) and ratings volume (8.3K vs 4). Insulator's Field Guide's advantage is review sentiment (100% vs 60%) and in-app purchases (none vs 8). On price, ads and device support there is nothing between them.

Both are free to download. ScanCoin sells 8 in-app purchases, starting at $7.99 per 7 days. Insulator's Field Guide asks for nothing beyond the download.

ScanCoin holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: ScanCoin has 8.3K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Insulator's Field Guide's written reviews are positive against 60% of ScanCoin's, so the app with the better star average is not the one people write more warmly about.

Insulator's Field Guide ships an update every 3 months, ScanCoin every 4 days. The most recent releases landed on October 6, 2026 and October 17, 2026 respectively.
