# GHL Connect vs Mobius

The clearest difference is rating: GHL Connect at 4.0 against Mobius's 2.0. GHL Connect also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (13.0 vs 15.6). Mobius's advantage is ratings volume (328 vs 4) and review sentiment (27% vs 17%). 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.

GHL Connect holds the better App Store score, 4.0 against 2.0. That said, the two scores are not equally well evidenced: Mobius has 328 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 17% of GHL Connect's written reviews are positive against 27% of Mobius's, so the app with the better star average is not the one people write more warmly about.

GHL Connect ships an update every 2 weeks, Mobius every 2 months. The most recent releases landed on September 10, 2026 and September 21, 2026 respectively.
