# RF vs RF Path

The clearest difference is rating: RF at 4.9 against RF Path's 3.5. RF also leads on review sentiment (91% vs 50%) and ratings volume (22 vs 4). RF Path's advantage is price ($2.99 vs $7.99) and chart position (#165 vs unranked). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

RF costs $7.99 and RF Path $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

RF holds the better App Store score, 4.9 against 3.5. That said, the two scores are not equally well evidenced: RF has 22 ratings behind it against 4, so its average is the more settled of the two.
