Verdict
The clearest difference is rating: Arc+ at 4.6 against Triangle Calculator's 3.7. Arc+ also leads on monetization model (free vs freemium) and ratings volume (113 vs 3). On price, update cadence, ads and in-app purchases 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. Arc+ sells 1 one-off in-app purchase and Triangle Calculator sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Arc+ holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Arc+ has 113 ratings behind it against 3, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on September 22, 2026 and October 7, 2026 respectively.
