Verdict

The call

The clearest difference is review sentiment: Scarlet at 92% against Breadpad's 34%. Scarlet also leads on rating (4.5 vs 3.9) and chart position (#16 vs #124). Breadpad's advantage is price (Free vs $2.99) and update cadence (fortnightly vs every 3 months). On ratings volume, ads, in-app purchases and device support there is nothing between them.
