# MudWatt Explorer vs Vernier Graphical Analysis

The clearest difference is rating: MudWatt Explorer at 2.8 against Vernier Graphical Analysis's 2.1. MudWatt Explorer also leads on iOS requirement (8.0 vs 17.7). Vernier Graphical Analysis's advantage is ratings volume (527 vs 14) and update cadence (every 2 months vs every 6 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

MudWatt Explorer holds the better App Store score, 2.8 against 2.1. That said, the two scores are not equally well evidenced: Vernier Graphical Analysis has 527 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 25% of MudWatt Explorer's written reviews are positive against 32% of Vernier Graphical Analysis's, so the app with the better star average is not the one people write more warmly about.

MudWatt Explorer ships an update every 6 months, Vernier Graphical Analysis every 2 months. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
