# GreenTrax vs Mugshot

The clearest difference is in-app purchases: Mugshot at none against GreenTrax's 4. Mugshot also leads on ratings volume (70 vs 1) and iOS requirement (14.0 vs 18.0). GreenTrax's advantage is rating (5.0 vs 4.8) and update cadence (every 5 weeks vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. GreenTrax sells 4 one-off in-app purchases. Mugshot asks for nothing beyond the download.

GreenTrax holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Mugshot has 70 ratings behind it against 1, so its average is the more settled of the two.
