Verdict
The clearest difference is in-app purchases: Glo at none against ShadowCalc's 3. Glo also leads on iOS requirement (15.1 vs 26.0). ShadowCalc's advantage is ratings volume (23 vs 1) and update cadence (weekly vs every 3 weeks). On price, rating, ads and device support there is nothing between them.
