Verdict

The call

The clearest difference is in-app purchases: FL Chart at none against Runestone Text Editor's 1. FL Chart also leads on rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.0). Runestone Text Editor's advantage is ratings volume (2K vs 1) and update cadence (every 2 weeks vs every 6 weeks). On price, ads and device support there is nothing between them.
