Verdict

The call

The clearest difference is in-app purchases: Stamp Duty at none against sked's 1. Stamp Duty also leads on device support (3 vs 1) and iOS requirement (12 vs 17.0). sked's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price there is nothing between them.
