Verdict
The clearest difference is in-app purchases: Trail Happy at none against CalcuSplit's 1. Trail Happy also leads on rating (5.0 vs 4.7) and iOS requirement (15.2 vs 18.0). CalcuSplit's advantage is update cadence (every 3 weeks vs every 6 weeks) and ratings volume (21 vs 3). On price, ads and device support there is nothing between them.
