Verdict
The clearest difference is review sentiment: Kmap at 100% against LogicGate's 0%. Kmap also leads on rating (5.0 vs 3.0) and in-app purchases (none vs 2). LogicGate's advantage is update cadence (fortnightly vs every 128 months). On price, ratings volume, ads and device support there is nothing between them.
