Verdict
The clearest difference is price: Carbon at Free against Bar Path's $4.99. Carbon also leads on rating (4.8 vs 3.0) and review sentiment (80% vs 50%). Bar Path's advantage is in-app purchases (none vs 9) and iOS requirement (11.0 vs 16.6). On ads, chart position and device support there is nothing between them.
