Verdict
The clearest difference is in-app purchases: Parentu at none against Grammatisch's 6. Parentu also leads on ads (none vs shown) and iOS requirement (12.0 vs 18.0). Grammatisch's advantage is update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.
