# Electrical Formulator vs Sketch Simply

The clearest difference is price: Electrical Formulator at Free against Sketch Simply's $0.99. Electrical Formulator also leads on rating (5.0 vs 3.6). Sketch Simply's advantage is review sentiment (50% vs 15%) and update cadence (every 11 days vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Electrical Formulator is free to download; Sketch Simply costs $0.99 up front. Electrical Formulator sells 1 one-off in-app purchase and Sketch Simply sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Electrical Formulator holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Sketch Simply has 5 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 50% of Sketch Simply'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, Sketch Simply every 11 days. The most recent releases landed on October 31, 2026 and November 2, 2026 respectively.
