# RLT SYSTEM vs ECHO Water

The clearest difference is rating: RLT SYSTEM at 3.0 against ECHO Water's 2.7. RLT SYSTEM also leads on iOS requirement (11.0 vs 15.1). ECHO Water's advantage is review sentiment (20% vs 0%) and ratings volume (52 vs 2). 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 2.7. That said, the two scores are not equally well evidenced: ECHO Water has 52 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of RLT SYSTEM's written reviews are positive against 20% of ECHO Water's, so the app with the better star average is not the one people write more warmly about.
