Verdict
The clearest difference is ads: Arc+ at none against Trigonometry Calculator.'s shown. Arc+ also leads on monetization model (free vs free with in-app purchases) and rating (4.6 vs 4.3). Trigonometry Calculator.'s advantage is update cadence (every 2 weeks vs every 4 months) and review sentiment (63% vs 50%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Arc+ sells 1 one-off in-app purchase and Trigonometry Calculator. sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Arc+ holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Arc+ has 113 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 50% of Arc+'s written reviews are positive against 63% of Trigonometry Calculator.'s, so the app with the better star average is not the one people write more warmly about.
Arc+ ships an update every 4 months, Trigonometry Calculator. every 2 weeks. The most recent releases landed on September 22, 2026 and October 9, 2026 respectively.
