Verdict

The call

The clearest difference is in-app purchases: Physical Constants at none against GCP's 2. Physical Constants also leads on iOS requirement (12.0 vs 15.0). GCP's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 9 months). On price and device support there is nothing between them.
