Verdict
The clearest difference is ads: LSSI at none against Electrical Calculations's shown. LSSI also leads on rating (5.0 vs 4.6). Electrical Calculations's advantage is ratings volume (128 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Electrical Calculations sells 3 in-app purchases, starting at $3.99 per 3 months and LSSI sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
LSSI holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculations has 128 ratings behind it against 1, so its average is the more settled of the two.
Electrical Calculations ships an update every 3 weeks, LSSI fortnightly. The most recent releases landed on October 18, 2026 and October 5, 2026 respectively.
