# C vs WAVZ

The clearest difference is rating: WAVZ at 5.0 against C's 4.5. WAVZ also leads on in-app purchases (none vs 11). C's advantage is ratings volume (2.3K vs 2) and update cadence (every 6 weeks vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.
