Verdict
The clearest difference is in-app purchases: Ultra TRF at none against Radio Code Master's 2. Ultra TRF also leads on ads (none vs shown). Radio Code Master's advantage is update cadence (every 5 weeks vs every 3 months). On price, device support and iOS requirement there is nothing between them.
