# Mobius vs FluvalConnect

The clearest difference is rating: FluvalConnect at 2.2 against Mobius's 2.0. FluvalConnect also leads on update cadence (monthly vs every 2 months) and iOS requirement (13.0 vs 15.6). Mobius's advantage is ratings volume (328 vs 33) and review sentiment (27% vs 18%). 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.

FluvalConnect holds the better App Store score, 2.2 against 2.0. That said, the two scores are not equally well evidenced: Mobius has 328 ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 27% of Mobius's written reviews are positive against 18% of FluvalConnect's, so the app with the better star average is not the one people write more warmly about.

Mobius ships an update every 2 months, FluvalConnect monthly. The most recent releases landed on September 21, 2026 and August 19, 2026 respectively.
