Verdict
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.
