Verdict
The clearest difference is rating: Ohms Law Calc. at 4.7 against CableApp's 3.0. Ohms Law Calc. also leads on ratings volume (1.3K vs 2). CableApp's advantage is in-app purchases (none vs 1) and review sentiment (61% vs 50%). On price, update cadence, ads and device support 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. CableApp asks for nothing beyond the download.
Ohms Law Calc. holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Ohms Law Calc. has 1.3K ratings behind it against 2, 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 61% of CableApp's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 14, 2026 and October 10, 2026 respectively.
