Verdict
The clearest difference is review sentiment: Unit Circle Calculator at 83% against Volume and Geometry's 20%. Volume and Geometry's advantage is rating (4.6 vs 3.4) and ratings volume (178 vs 8). 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. Volume and Geometry sells 2 one-off in-app purchases and Unit Circle Calculator sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Volume and Geometry holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Volume and Geometry has 178 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 20% of Volume and Geometry's written reviews are positive against 83% of Unit Circle Calculator'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 3 weeks. The most recent releases landed on August 6, 2026 and August 26, 2026 respectively.
