# Lytes vs RXFiles +

The clearest difference is price: RXFiles + at Free against Lytes's $2.99. RXFiles + also leads on rating (5.0 vs 4.8). Lytes's advantage is review sentiment (67% vs 50%) and ratings volume (10 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

RXFiles + is free to download; Lytes costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

RXFiles + holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Lytes has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Lytes's written reviews are positive against 50% of RXFiles +'s, so the app with the better star average is not the one people write more warmly about.

Lytes ships an update every 3 months, RXFiles + every 6 months. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
