# LeafSpy Pro vs Tessie

The clearest difference is price: Tessie at Free against LeafSpy Pro's $19.99. Tessie also leads on rating (4.8 vs 3.5) and update cadence (weekly vs every 2 months). LeafSpy Pro's advantage is in-app purchases (none vs 17) and chart position (#16 vs unranked). On ads, device support and iOS requirement there is nothing between them.
