Verdict
The clearest difference is in-app purchases: Meridian at none against Impact protocol's 7. Meridian also leads on rating (5.0 vs 4.7) and update cadence (every 6 days vs monthly). Impact protocol's advantage is ratings volume (32 vs 3). On price, ads, device support and iOS requirement there is nothing between them.
