# Electrical Formulator vs ElectricalWiringPro

The clearest difference is rating: Electrical Formulator at 5.0 against ElectricalWiringPro's 3.4. ElectricalWiringPro's advantage is in-app purchases (none vs 1) and review sentiment (40% vs 15%). On price, update cadence, ads and device support there is nothing between them.

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

Electrical Formulator holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: ElectricalWiringPro has 8 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 40% of ElectricalWiringPro's, so the app with the better star average is not the one people write more warmly about.

Electrical Formulator ships an update every 2 months, ElectricalWiringPro every 5 weeks. The most recent releases landed on October 6, 2026 and October 5, 2026 respectively.
