# Electrical Formulator vs Prysmian Group Conduit Fill

The clearest difference is rating: Electrical Formulator at 5.0 against Prysmian Group Conduit Fill's 2.7. Electrical Formulator also leads on update cadence (every 2 months vs every 7 months). Prysmian Group Conduit Fill's advantage is in-app purchases (none vs 1) and ratings volume (6 vs 1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Electrical Formulator sells 1 one-off in-app purchase. Prysmian Group Conduit Fill asks for nothing beyond the download.

Electrical Formulator holds the better App Store score, 5.0 against 2.7. That said, the two scores are not equally well evidenced: Prysmian Group Conduit Fill has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 15% of Electrical Formulator's written reviews are positive against 20% of Prysmian Group Conduit Fill's, so the app with the better star average is not the one people write more warmly about.
