# LeafSpy Pro vs MPG Loyalty

The clearest difference is price: MPG Loyalty at Free against LeafSpy Pro's $19.99. MPG Loyalty also leads on rating (4.9 vs 3.5) and iOS requirement (13.0 vs 16.0). LeafSpy Pro's advantage is update cadence (every 2 months vs every 11 months) and ratings volume (115 vs 8). On review sentiment, ads, in-app purchases and device support there is nothing between them.

MPG Loyalty is free to download; LeafSpy Pro costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

MPG Loyalty holds the better App Store score, 4.9 against 3.5. That said, the two scores are not equally well evidenced: LeafSpy Pro has 115 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 46% of LeafSpy Pro's written reviews are positive against 40% of MPG Loyalty's, so the app with the better star average is not the one people write more warmly about.

LeafSpy Pro ships an update every 2 months, MPG Loyalty every 11 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
