Verdict
The clearest difference is rating: Ohms Law Calc. at 4.7 against WireGo's 3.7. Ohms Law Calc. also leads on ratings volume (1.3K vs 9). WireGo's advantage is ads (none vs shown) and update cadence (monthly vs every 2 months). On price, review sentiment, 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. Ohms Law Calc. sells 1 one-off in-app purchase and WireGo sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Ohms Law Calc. holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Ohms Law Calc. has 1.3K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 50% of Ohms Law Calc.'s written reviews are positive against 57% of WireGo's, so the app with the better star average is not the one people write more warmly about.
Ohms Law Calc. ships an update every 2 months, WireGo monthly. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
