# Attenuator vs Electrical Calculator lite

The clearest difference is review sentiment: Attenuator at 100% against Electrical Calculator lite's 41%. Attenuator also leads on ads (none vs shown) and rating (5.0 vs 4.6). Electrical Calculator lite's advantage is update cadence (every 5 weeks vs every 7 months) and ratings volume (574 vs 8). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Attenuator sells 1 one-off in-app purchase and Electrical Calculator lite sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Attenuator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculator lite has 574 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 100% of Attenuator's written reviews are positive against 41% of Electrical Calculator lite's.

Attenuator ships an update every 7 months, Electrical Calculator lite every 5 weeks. The most recent releases landed on July 29, 2026 and September 18, 2026 respectively.
