Verdict
The clearest difference is review sentiment: LingoFlow at 100% against Charging Engine's 52%. LingoFlow also leads on in-app purchases (none vs 12) and rating (5.0 vs 4.8). Charging Engine's advantage is ratings volume (11K vs 2) and iOS requirement (12.0 vs 18). On price, ads and device support there is nothing between them.
