# Ampère Mobile vs Electrical Calculations

The clearest difference is review sentiment: Electrical Calculations at 87% against Ampère Mobile's 25%. Electrical Calculations also leads on update cadence (every 3 weeks vs every 11 months) and ratings volume (126 vs 1). Ampère Mobile's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Electrical Calculations sells 3 in-app purchases, starting at $3.99 per 3 months. Ampère Mobile asks for nothing beyond the download.

Ampère Mobile holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculations has 126 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Ampère Mobile's written reviews are positive against 87% of Electrical Calculations's, so the app with the better star average is not the one people write more warmly about.

Ampère Mobile ships an update every 11 months, Electrical Calculations every 3 weeks. The most recent releases landed on June 25, 2026 and September 22, 2026 respectively.
