# Triangle Solver vs Geometry!!

The clearest difference is in-app purchases: Triangle Solver at none against Geometry!!'s 2. Triangle Solver also leads on ads (none vs shown) and review sentiment (75% vs 67%). Geometry!!'s advantage is rating (4.5 vs 4.2) and update cadence (every 7 months vs every 21 months). On price, ratings volume and device support there is nothing between them.

Both are free to download. Geometry!! sells 2 in-app purchases, starting at $0.99 per year. Triangle Solver asks for nothing beyond the download.

Geometry!! holds the better App Store score, 4.5 against 4.2. Both are backed by a comparable volume of ratings — 31 and 56 respectively. Written reviews complicate that: 75% of Triangle Solver's written reviews are positive against 67% of Geometry!!'s, so the app with the better star average is not the one people write more warmly about.

Triangle Solver ships an update every 21 months, Geometry!! every 7 months. The most recent releases landed on October 3, 2026 and September 28, 2026 respectively.
