Verdict
The clearest difference is in-app purchases: Trig Solver at none against Ohms Law Calc.'s 1. Trig Solver also leads on ads (none vs shown) and review sentiment (74% vs 50%). Ohms Law Calc.'s advantage is update cadence (every 2 months vs every 28 months) and rating (4.7 vs 4.3). On price 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. Trig Solver asks for nothing beyond the download.
Ohms Law Calc. holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Ohms Law Calc. has 1.3K ratings behind it against 78, so its average is the more settled of the two. Written reviews complicate that: 74% of Trig Solver's written reviews are positive against 50% of Ohms Law Calc.'s, so the app with the better star average is not the one people write more warmly about.
Trig Solver ships an update every 28 months, Ohms Law Calc. every 2 months. The most recent releases landed on September 22, 2026 and September 8, 2026 respectively.
