Verdict

The call

The clearest difference is review sentiment: ConvertPilot at 100% against PDF Expert's 45%. ConvertPilot also leads on in-app purchases (none vs 10) and rating (5.0 vs 4.7). PDF Expert's advantage is ratings volume (217K vs 1) and update cadence (fortnightly vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
