Verdict
The clearest difference is rating: Electrical Parallel Calculator at 4.7 against Singular's 1.0. Electrical Parallel Calculator also leads on in-app purchases (none vs 3) and ratings volume (33 vs 1). Singular's advantage is update cadence (daily vs every 8 months). On price, ads, device support and iOS requirement 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. Singular sells 3 in-app purchases, starting at $4.99 per 7 days. Electrical Parallel Calculator asks for nothing beyond the download.
Electrical Parallel Calculator holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Electrical Parallel Calculator has 33 ratings behind it against 1, so its average is the more settled of the two.
Electrical Parallel Calculator ships an update every 8 months, Singular daily. The most recent releases landed on October 7, 2026 and September 27, 2026 respectively.
