Verdict

The call

The clearest difference is in-app purchases: Triangle Solver at none against Geometry Calculator lite's 1. Triangle Solver also leads on ads (none vs shown) and review sentiment (75% vs 42%). Geometry Calculator lite's advantage is update cadence (every 5 weeks vs every 21 months) and rating (4.5 vs 4.2). On price, ratings volume and device support there is nothing between them.
