# Add Sub K vs Kodable Basics

The clearest difference is review sentiment: Add Sub K at 100% against Kodable Basics's 55%. Add Sub K also leads on in-app purchases (none vs 7) and iOS requirement (10.0 vs 15.0). Kodable Basics's advantage is rating (4.7 vs 3.0) and update cadence (every 3 weeks vs every 10 months). On price and ads there is nothing between them.

Kodable Basics holds the better App Store score, 4.7 against 3.0.

Written reviews complicate that: 100% of Add Sub K's written reviews are positive against 55% of Kodable Basics's, so the app with the better star average is not the one people write more warmly about.
