# Sunlighten vs RLT SYSTEM

The clearest difference is ratings volume: Sunlighten at 77 against RLT SYSTEM's 2. Sunlighten also leads on review sentiment (19% vs 0%). RLT SYSTEM's advantage is rating (3.0 vs 2.8) and iOS requirement (11.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

RLT SYSTEM holds the better App Store score, 3.0 against 2.8. That said, the two scores are not equally well evidenced: Sunlighten has 77 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 19% of Sunlighten's written reviews are positive against 0% of RLT SYSTEM's, so the app with the better star average is not the one people write more warmly about.
