Verdict
The clearest difference is in-app purchases: Color Encoder at none against SmoothKey's 3. Color Encoder also leads on device support (3 vs 1) and iOS requirement (11.2 vs 16.0). SmoothKey's advantage is update cadence (every 2 days vs every 8 months). On price and ads there is nothing between them.
