Verdict

The call

The clearest difference is review sentiment: iCalc Triangle Calculator Pro at 100% against GeoGebra Geometry's 55%. GeoGebra Geometry's advantage is monetization model (free vs paid) and rating (4.0 vs 3.6). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

GeoGebra Geometry holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: GeoGebra Geometry has 76 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 55% of GeoGebra Geometry's written reviews are positive against 100% of iCalc Triangle Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GeoGebra Geometry ships an update monthly, iCalc Triangle Calculator Pro every 19 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
