Verdict
The clearest difference is in-app purchases: Quick Key at none against Grade Grid's 1. Quick Key also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 13 months). Grade Grid's advantage is iOS requirement (13.6 vs 17.0). On price and device support there is nothing between them.
