Verdict
The clearest difference is in-app purchases: Sigma Mini at none against PermitLog's 1. Sigma Mini also leads on iOS requirement (11.0 vs 18.0). PermitLog's advantage is rating (4.5 vs 4.0) and update cadence (every 2 weeks vs every 2 months). On price, ratings volume, ads and monetization model there is nothing between them.
